No reverse protection. Apply 12V or 24V when the label says 5V, well, bye

Look down.

Gerald

If you are interested in an *Altium* version, there is a version for the
original A5B board they can be found at Altium A5B
<https://github.com/CircuitCo/-BeagleBone-Black-RevA5/blob/master/BeagleBoardBlack_RevA5_Altium.zip?raw=true>.
These files are provided *AS IS* with no support.

If you are interested in an *Mentor* version of the A5C board they can be
found at Mentor A5C
<https://github.com/CircuitCo/-BeagleBone-Black-RevA5/blob/master/Mentor_BBB_A5C.zip?raw=true>.
These files are provided *AS IS* with no support.

Mentor has also recently released a PADS version of the board at PADS
BeagleBone Black <http://www.pads.com/reference-designs/bb-bblk-000>.

You can find the Solid Works and 3D PDF files provided AS-IS at 3D Models
<https://github.com/lgxlogic>

A GitHub repo is available with all revisions of the documentation -

Re: [beagleboard] How to Identify My BBB

[Gerald Coley]

The labels have pictures in the SRM describing what they mean as well, for
those that are not afraid of documentation.

Re: [beagleboard] Working links to blank-EEPROM flasher image?

[Gerald Coley]

Take a real BBB and copy the contents if you need to. EEPROM data varies
with serial number and revision data. But the EEPROM data is described in
the SRM, is still valid and is not stale or old.

Just make sure you ground the Write Protect pin on the EEPROM.

Re: [beagleboard] BBB P8/P9 GPIO pin availability

[Gerald Coley]

Definitely can add a lot of parts around it. Then again the board would
cost more and everyone would pay for that feature, whiter they used it or
not..

It would be less expensive to just add it to the cape on an add needed
basis  and not on every single pin.

 If you are concerned, use the bus-isolation /transmission-gate  chips,

 I suspect it was done deliberately to help with the "don't drive the
 rest of the pins" issue.

 A little 5V to 3.3V regulator to power your LVC "input" IC will work
 nicely.
 Provided that it is powered at the same time the BBB is.
 That is, use VDD_5V if powered from the power jack.

 Relative to power appearing at the power jack:
 SYS_5V is delayed 50 ms.
 VDD_3V3B is delayed 100 ms.
 SYS_RESETn is delayed ~130 ms.

 I have not measured power supply sequencing when powered by USB.

 Or if you are dealing with both I and O on the boot pins, use something
 like
 a 74CBTLV3126 bus switch / transmission gate to  isolate your circuitry
 from the BBB while it is booting.  Just make sure the bus-switch /
 transmission-gate
 is powered while the BBB is booting.

 This issue only comes up about once a week here on the forum.  :-)

Re: [beagleboard] Damaged Beagle Bone Black (neither boots nor supplies VDD_3V3B)

[Gerald Coley]

Without knowing what exactly the damage is, I can't tell you what caused it.

My suggestion is to send it in and let us figure out if we can what
happened.

Re: [beagleboard] SPI and I2C port use?

[Gerald Coley]

EEPROM is in I2C0 which does not connect to the expansion headers. I2C2 is
a shared bus. As long as no tow devices have the same address, you are
limited to 255 different devices on an I2C bus.

SPI has a dedicated CS line. You can and that with a GPIO pin and create
more CS signals if you like.

CODECS typically uses I2S which is a totally different animal. But there
are SPI and I2C CODECs out there.

Re: [beagleboard] Re: operating temperature range of Beaglebone Black

[Gerald Coley]

It should not be. But you need to capture what the failure is by monitoring
the terminal output continuously...

It could be the power supply. Current rating?
Is it in a box?
Is it running from a SD card?
What is the connectivity method, RJ45? WIFI?
Is there a cape?

More information will help.

 In SRM Rev A5A I see that the AM3359 processor is rated for -40 to 90
 degrees C.  Micro's page
 http://www.micron.com/parts/nand-flash/managed-nand/mtfc2gmtea-wt says
 mtfc2gmtea-wt is rated for -25 to 85 degrees C. I suppose there might be
 tighter constraints from other components.

 I have made a procedure in which the user presses a combination of

 runs the system(shutdown -h now) command in my C++ program.

 Is a shutdown procedure required for the BBB or will just pulling

 I have read in some sites that the eMMC could get corrupted causing

 Please advise

Re: [beagleboard] RAM 1GB option

[Gerald Coley]

From a schematic and PCB standpoint we can go up to 128GB, after the first
of the year. Assuming we have enough powernobody gripes about ti not
working on USB...and people are willing to pay.and the SW can support
it, it should be doable.

  what DAC do you use? How much eMMC storage do you need?

 I have yet to select the DAC/CODEC. Some TI part, most likely. I need to
 drive small speakers, so it'll probably be one without an integrated amp. I
 also only need mono, but to make the cape a little more capable (lulz), I'm
 going to try to make it stereo with an amp bridging option.

 As to how much, it's an open-ended question that would depend on cost. 16
 GB? 32 GB? 64 GB? More is always better, but cost is a limiting factor. I
 do know the current 4GB isn't enough, but 8GB would be enough to store the
 library of content that inspired my project.

[beagleboard] Re: BeagleBoard.org Approved accessories

[Gerald Coley]

Approving accessories is a little tricky. No revision control and no source
control. We see this all the time on Wifi modules. Different revision
silicon and different silicon all together.

You would need this to be a direct relationship with the supplier of the
accessories. And we woudl need to find a away to test hem and stay in step
with the suppliers on any changes. We also have the case where the Linux
kerenl gets updated every now and then which can lead in some cases to an
accessory no longer working.

This will take some hard resources to do this correctly.

  I've been bugged quite a bit lately for permission to use the

  applied the BeagleBoard Compatible logo (http://beagleboard.org/logo)
  on packages and this is a no-no. That logo is only meant for people
  doing interesting board spins of their own where they engage Robert
  and myself to make sure the default software image still runs on their
  board and they pay a license fee into the Foundation to hopefully help
  us fund open development and sponsorships.
 
  Anyway, I'd like to try to provide some kind of logo people can use
  for accessories (capes, cases, peripherals, etc.). There is already a
  list, mostly maintained by Gerald, on the wiki at
  http://elinux.org/Beagleboard:BeagleBone_Black_Accessories. This is a
  great place to start and I'll import all of the items listed there if
  people believe this is a useful exercise (and back annotate as well).
  However, making some sort of page on BeagleBoard.org backed by a logo
  people can put on their products and web pages seems like a good next
  step. I'm open to the thought that this is a bad idea or needs
  tweaking, so please review and respond.
 
  http://beagleboard.org/approved/
 
  Here's my first attempt at how to get approved:
 
  There's no charge for being BeagleBoard.org Approved, just a
  verification that needs to happen. There's no promise your product
  will be approved, but we want people to know to use your product if it
  is of good quality and compatibility.
 
  First, you'll need to send samples of your product to Robert, Gerald
  and Jason at a minimum so that they can test compatibility. Jason will
  send you shipping addresses and you can find his e-mail address on
  http://beagleboard.org/about. The product won't be returned because it
  will be used in testing future compatibility as well.
 
  Second, if any software is required to support your product, you'll
  need to make sure it is in the default images built by
  http://bit.ly/beagle-image-builder.
 
  Finally, you should wait to get a confirmation e-mail from jkridner at
  beagleboard.org with a vector PDF of the logo for inclusion on your
  website, package or product.

Green is the Seed Studio $39 special.

It will cost more. If Jason approves the cost increase we can make it
happen on a Rev D board.

X15 with 4GB would be nice. Try $40 more! I just want to see the 2G working

Re: [beagleboard] BeagleBone Black doesn't sometimes start. Only Power LED is on

[Gerald Coley]

3,3V and 5V shorted together would most certainly have been something
undesirable. Pity that the FTDI only puts out 5V on that header and not a
voltage level that is the same as the signal level.

The purpose of the buffer which was to prevent current coming from the the
FTDI signals and powering the processor when power was off and the FTDI
cable was still plugged in. It actually made it worse when we tried a
pullup. So the weak pulldown was a compromise.

If we ever do another revision, which is doubtful with all those clones out
there, I would consider adding a pullup on the other side of the buffer
again and see if we can get it to work.

You could create a pullup by using  a voltage divider between the 5V rail
and ground and connecting your pullup to that.

Or you can add look at adding pullup via SW on the RX pin.

 I just took a look at Rev C schematics and there is a 100K pulldown on the

 pull up is what you want - that at least is idle state on a serial line
 (from what I recall). My gut feel would be to use around a 3K resistor
 would should allow plenty headroom for hooking up a serial monitor if you
 ever wanted to - its a real pity that there is no convenient 3V3 on the

 I'll chime in again too - we originally tested our 3v3-rx jumper with a
 direct connection, but then decided it might be nice to keep the ability to
 use the serial debug port.  Right now we've got a 470 ohm resistor pulling
 rx up, which seems to allow communication over serial still.  We also tried
 values of 220 through 1kohm and were still able to send characters to
 uart0.  100 ohm was too low to send anything over serial.  I've not done
 extensive reboot testing yet with each of these, but we will likely settle
 on either 470 or 1kohm.

 If you probe the RX pin of the BB with nothing attached, we find 0v.  The
 TX pin (both on the BB and on the FTDI board we attach to the BB) is at
 3.3v by default, and we've also noticed that the problem never occurs when
 we're hooked up to uart0 with our FTDI chip adapter.  That made pulling the
 line up rather than down an attractive option.  We did try pulling RX down
 to ground at some point, but the very first test I did after that resulted
 in power LED on but no boot.

 We still haven't done a mass deployment, so for now I'm taking our smaller
 testing runs and experiences like Ivan's to guide us.  Sidenote - yes, we
 have noticed eth0 not showing up as well, although it's not critical for
 our application.

 this pin is pulled low (which I still think is wrong polarity) on rev C

 In addition, we have physically blocked off the PWR button and only
 expose the reset button via a small pin hole in our enclosure.

 Hi Robert,

  Please confirm which kernel your running

 3.8.13-bone71 (updated beginning of last June)

  There's a big thread on this list, where a bunch spend about 2 weeks
 bisecting the v4.1.x kernel to find the cause of the random reboot..

 I don't have an issue though with random reboots - the reboots are
 initiated on purpose by my application (because of the eth0 problem) - but
 as described 2 in 30,000 reboots failed.

 Cheers,
 Ivan

Re: [beagleboard] RAM 1GB option

You need to ask the President as to his plans. Considering the fact hat the
cost of the board will jump in price, most likely not.

I will be producing boards in the future with this option.

Re: [beagleboard] Re: BBB DPLL boot problem

[Gerald Coley]

Sounds like a shorted I/O pin on the processor. When it does not boot it it
is because the PMIC is shutting down due to excessive current. Sounds like
you are squeaking by and the PMIC is not shutting you down. 600 mA is too
high.

 I tried to google the error message and had no success finding a solution

 Does anybody have any idea on what might have caused that error? Any idea

Yes. It is called the AM3358 Technical Reference Manual for the processor.

The design information on the board itself is found on the link I sent

Re: [beagleboard] GPIO activation during startup

[Gerald Coley]

Add a pullup or  just use a GPIO that defaults to high. Nothing is faster
than that.

 Hi,

 I need to set a GPIO output high as early as possible during the startup
 and keep it active until the system shuts down. What I did so far:

 - Use GPIO 0.7 for testing
 - Set GPIO0.7 high in python script automatically after startup - GPIO
 becomes high approx. 24s after power-on
 - Modify device tree to set GPIO0.7 high - GPIO becomes high approx. 9s
 after startup
 - Set GPIO0.7 high in u-boot scipt (/boot/boot.scr) - GPIO becomes high
 after approx. 3.5s, but becomes low again after approx. 6s

 My problem now is that the GPIO becomes low for approx. 3s after it was
 set by u-boot and before the device tree. I guess I need to understand the
 kernel boot process a little bit better. Any suggestion, where to start or
 any hint where to look at?

Re: [beagleboard] Re: shutdown procedure required for beaglebone black ??

By doing this you can get corruption. Linux requires that you unmount the
drives before powering down.

There is also a Linux shutdown command that can be used.

 485 network using appropriate drivers).

 I have almost developed the hardware and the software using Eclispe C++
 IDE.

 As I am not using any batteries or other power backup devices for the
 BBB, Do I have to implement a shutdown procedure for my users ??

 I have made a procedure in which the user presses a combination of keys
 to get the shutdown option on the LCD, selecting the shutdown option runs
 the system(shutdown -h now) command in my C++ program.

 Is a shutdown procedure required for the BBB or will just pulling out
 the +5V power jack be sufficient.

 I have read in some sites that the eMMC could get corrupted causing
 startup issues

 Please advise

 Hi.
 Sorry for the delay, attached is a pdf with the schematic. I tried to
 take some pictures of my wiring and also to triple check the connections,
 but the lab was closed for fumigation.

 Some other points are:
 - I am using both PRUs to read some encoders and generate four PWM
 signals (10bits @ 12KHz). In this schematic only the encoder inputs are
 complete.
 - I am powering this cape with a switched industrial grade power
 supply. When I power up the board from the DC jack I am using a cheap
 adapter (also switched).
 - If I power up from usb and after the board boot process I connect the
 power to the extension cape, then I can read one encoder (have not tested
 the others but they should).

 Thank you,

Re: [beagleboard] Question about applying voltage to an unpowered BBB.

[Gerald Coley]

I know it is a bit confusing. If you do, it will blow up the processor. It
is a function of the processor.

I suggest you read the datasheet on the processor as it relates to power
sequencing.

http://www.ti.com/product/AM3358/technicaldocuments

Until the 3.3V rail comes up, nothing on your board can be powered up.Even
if it is from the same source. Again, it is a matter of power sequencing.
All the rails must come up and power down in a particular sequence. Violate
that sequence, then you are asking for trouble.

Power your circuit off of the VDD_3V3B rail or use the VDD_3V3 rail to
enable the power on any external circuitry that connects to a pin on the
processor.

 Alright, I know that there are a lot of discussions on here about this
 topic, and I have read through them, but I am still a bit confused about
 this line in the manual:
 NOTE: DO NOT APPLY VOLTAGE TO ANY I/O PIN WHEN POWER IS NOT SUPPLIED TO
 THE BOARD. IT WILL DAMAGE THE PROCESSOR AND VOID THE WARRANTY.
 NO PINS ARE TO BE DRIVEN UNTIL AFTER THE SYS_RESET LINE GOES HIGH.

 I am working on a project that will involve me using multiple sensors with
 the BBB that are powered from another source. One of those sensors is a GPS
 that spits out data as long as it is powered, but the others only send data
 after they have received a request. Here are my questions:

 1. Based on that statement, it is my understanding that if the GPS I'm
 using is powered and the BBB is not, then the BBB will be damaged. Is this
 accurate?
 2. What if the board and all the sensors are powered from the same source
 controlled by a single switch? Will this damage the board when I flip on
 the switch?
 3. What if I power all the sensors from the board itself so that it is
 impossible for them to receive power before the board does? Will this
 damage the board?

 Background: I’m developing a complicated prototype and I am new to

 beginning to understand that, like any device, more capability comes with
 more complexity and vulnerabilities. I still see the BBB as an amazing
 opportunity for inventors overall and realize that I need to learn more to
 use it properly.

 I cannot point to one circuit that caused the damage to
 the BBBs because I am trying different arrangements to integrate multiple
 devices. However, if you could answer some basic questions on design
 strategy, that could help.


 *Here’s what I need to accomplish:*

 I need to power 4 accessories: (1) a small stepper motor through the
 Pololu DRV8834 driver board. It consumes about 200 – 300 mA at 5 volts, (2)
 an IC chip via pulse wave modulation – it requires about 620mA at 1.55V,
 (3) a small DC motor which consumes about 40 mA at 3V (either by PWM and
 a relay or straight from a 3.3 V source) and (4) a small cooling fan –
 consumes about 120 mA at 5 V.

 I need to control turning all these on and off by a clock function.

 I need to read a GVS digital sensor:  consumes less than 10 mA at 5 V.

 I need to read a GVS analog input:  5V input, output  1 volt.

 I need to read DC voltages (analog): (1) on a pin on the DRV8834 driver
 board (0-1 volt range), (2) on a sensor with special input requirements –
 it needs both (+) 5 volts AND (-) 5 volts inputs to power it. The (-)
 voltage is derived from (+) 5 V using this inverter ICL7660A, which I have
 found to be about 91% efficient at converting DC (+) to DC(-) for this
 application. Sensor output max about 1.2 volts.

 Finally, I need to add and read a real time clock (RTC) such as the
 Chronodot (Adafruit) – requires I2C bus SDA, and SCL, as well as GND and
 (+) 5V.


 *What do you think of these strategies:*

 (1)Use the BBB-GVS board (http://beagleboard.org/project/BBB-GVS/).
 This board appears to provide a layer of protection from the sensor voltage
 inputs and power outputs for the BBB. The problem is they may not be a
 reliable supplier and I cannot tell if this board will accomplish all these
 tasks.

 (2)Use the BBB only for logic and supply all the power from an
 independent (probably 5V cell phone charger power pack) source with voltage
 regulator, using PWM and relays to regulate the voltages lower than 5 V and
 relays to control intermittent power needs. Would this be safer for the BBB
 i.e. not using power directly off the BBB while trying to read sensor
 output at the same time? It seems dangerous to me tying all the grounds
 together (analog, digital and power) that would be required to get both
 power out of the BBB and signal into it.

 (3)Power the BBB via a 3.7 volt backup battery through TP5 and TP8
 to prevent abrupt cessation of power should a system failure occur. Seems
 like it would be possible to write code to give the “sudo shutdown –h now”
 command when the power went down. This would allow the PMIC time to do an
 orderly shutdown.



 I suspect that the sensors may be putting voltages on the BBB pins
 before they are powered up as part of the problem, but I am not sure how to
 prevent this. Is there a way to power up the sensors after the BBB has
 properly booted and to shut them down before the PMIC does its shutdown
 sequence? Any other external wiring or devices that could help safeguard
 the BBB? Any advice you can offer on any of this or other ways to protect
 the BBB would be appreciated.

 not sustain the power button nor boot up.

 This seems to be a repetitive theme on this forum. I am losing faith in
 the BBB ever functioning in a real world environment if it is this fragile.
 Is there any way to protect the BBB processor (or whatever is blowing) with
 external circuitry or power?

 Appreciate any help. I'm now out over $200 with these boards and I cannot
 identify anything that should be damaging them. Considering changing to
 another system at this point. Although I am impressed with the capability
 of the BBB, I would not call it a robust system.

 I had a similar problem- my power LED would just continue blinking

 First, I checked if my BBB was still alive. To find that, I connected my

 normally. Then to make sure that everything was properly, I ran some
 program as given in the BB website
 http://beagleboard.org/getting-started.  I was happy to see, the
 programs on the website worked just fine on my board. Thus, I was able to
 conclude that strangely, my BBB board didn't like 5V external power 
 source!

 was
 also a GPS module attached to one of the UARTs and a probably power 
 hungry
 USB wlan stick that I'm trying to get to work, so a power hungry setup.

 I was ready to declare it dead, it remained just flashing once after
 repeatedly unplugging and reattaching the power supply.

 However I noticed the single power led flash would also happen if I
 pressed the power button (leaving the 5V plug in). Doing that repeatedly
 seems to have revived the board, will see if new problems occur. For now 
 it
 behaves normally.

 Is this expected behaviour?

 Does the DM3730 boot ROM code do that?

Re: [beagleboard] Xray Safe, is it?

[Gerald Coley]

TI devices are not approved for use in medical devices. There are XRAY
machines that are used to XRAY PCBs. I doubt those qualify as medical
devices..

 I have to admit. I have never taken an Xray of a BBB. It should not be an
 issue. However, to be sure, I suggest you take the BOM and contact each

Re: [beagleboard] BB X15, any status?

These boards are what we call the Beast. Any issues that may show up will
be based on any added SW that can bring them out. This board is very over
designed and we have been working on it for 20 months. It has been run
through the ringer. SW is the big question.

Re: [beagleboard] BBB powers from USB but not from 5VDC, cape powers only with 5VDC

[Gerald Coley]

Sounds like the board has been damaged and needs to be repaired.

 I gather the BBB can be powered either by USB or by 5VDC, but not both.

 So I don't understand. My BBB does not power up at all with 5VDC
 connected. As soon as I connect USB, however, it boots right up.

 Meanwhile, I have a cape (CBB-Relay) that requires 5VDC. It doesn't work
 unless I then connect both USB and 5VDC.

 As I've read more than once, it can be powered either by USB or by 5VDC.

 But what am I supposed to do when I need to power it by 5VDC to get the
 cape working, /and/ I want to be able to use the USB connection for
 development?

 If I've fried my BBB while trying to figure this out, why would it work at
 all with both 5VDC and USB connected (realizing that it can be powered
 either by USB or by 5VDC, but not both)? It works just fine, and in fact
 the only way it works, is if I connect both 5VDC and USB.

 What am I missing?

Re: [beagleboard] Beaglebone Black rev C color problems (Debian Wheezy 7.8)

[Gerald Coley]

You cannot do 24b and say 1920x1080 resolution. There is not enough memory
bandwidth. That is why it is 16bits instead of 24bits on the BBB.

If 24b is that critical, then you need to cut the resolution back. Also,
the pin mapping is different for 24b vs 16b. All the colors get scrambled.
You can look at the TRM for some delightful reading if you need more
details on that. IF you set the processor for 24b mode, the colors are all
wrong on the BBB.

  Sorry the NXP HDMI adapter used on the BBB only has 16 physical lines

I defer to the creator of BoneScript to answer that. I assume that if the

 I have two theories:

Re: [beagleboard] Industry Standard?

[Gerald Coley]

Beagle board has no money so no chance we can go bankrupt. We are what is
called a non-profit.

Everything is open source so you can always build it yourself. People do it
all the time.

Re: [beagleboard] Pin Acting Odd

[Gerald Coley]

Take a look at the schematic. GPIO3_21 is connected to the output of a
clock generator. To use it you must disable the Oscillator.

*Oscillator can be disabled via SW*
*for power down modes or if*
*GPIO3_21 needs to be used*

My suggestion is to pick another pin to work with. Less headaches.

Gerald

 Hey all,

 I am pretty new to the BBB and I came across something pretty odd that I
 have been trying to figure out for a few hours now as I was creating a push
 button circuit:

 P9_25 is a GPIO pin.  I set it to input but noticed that it would not
 respond to my button.  After some digging I realized that the pin itself
 was acting funky, so I isolated it to run some tests with BB's Bonescript
 tutorial on GPIO digitalWrite().  I ran this code below (apologies for the
 sloppy picture) with the adjacent circuit configuration shown as well.
 Obviously, the LED should turn off, but it doesn't:



 https://lh3.googleusercontent.com/-UVZwTNBSR00/VZ3RjMNpQiI/AGM/mjWtyKl5LTw/s1600/20150708_212210.jpg
 https://lh3.googleusercontent.com/-lmn1_9_NGTM/VZ3PwVv6MLI/AF4/-yVeDLNf7fY/s1600/20150708_212158.jpg


 I then tried the same tests on other pins, such as P9_26, and it worked
 perfectly, so that's where I'm startled.


 I have two theories:


 1)  I messed with P9_25 in the past, and it is reconfigured in a weird
 way; if someone has this hunch, could you please perhaps inform me how to
 reset the pin to its original glory?


 2) The pin is busted.  Fingers crossed for #1.


 If anybody has run into something similar, or has any idea what I should
 do, please let me know!


 Thank you for you time.


 -Joe

Re: [beagleboard] Can you switch I/O pins from SPI0 to GPIO?

[Gerald Coley]

The AM3358 does not support tri-state on GPIO pins.

Gerald


On Mon, Jul 6, 2015 at 4:24 PM, drhunter1...@gmail.com wrote:

 Hello All,

 I've have a BeagleBone Black connected with SPI0 to an FPGA and also to
 it's configuration flash memory device on a cape we are developing.   On
 power up, the FPGA will configure correctly from the serial.  (SPIDEV0 is
 not enabled in the device tree).   I can also reprogram the flash with SPI0
 at this point.  The idea is that either the BBB or the FPGA will talk to
 the flash and the other will be tri-stated.

 I'm using the Adafruit_BBIO driver to communicate with the FPGA over SPI0
 (using Python).

 The issue I have is that when I exit the Python program, the SPI0 pins are
 still configured for SPI (even after using the SPI.close() function in the
 program).  I'm looking at the cape manager slots after the program exits
 and SPIDEV0 is now loaded.After that, I'm not able to re-configure the
 FPGA because the SPI lines are being driven by the BBB.

 The question is:  Is it possible to tri-state the SPI0 lines or switch the
 SPI0 lines back to GPIO inputs before I exit the python program?

 Any insight is appreciated.

 Thanks,
 Dave

 application code on U3 will be to program an external FPGA for which we
 plan to use LOGI BONE V2. Programming interface may be a serial interface.

 This is a small learning exercise that we want to do for future

 Now I want to enquire the following:-

 1) If we consider only BBB and LOGI BONE V2, whether BBB will be able to
 program through Serial Interface the Spartan 6 FPGA on LOGI BONE V2? Has
 some one done the same or some idea on this? I can see SPI1 interface
 coming on the expander of BBB.

 2) Can I connect BBB, My Cape and LOGI BONE V2 together? What can be the
 cares that may have to be taken apart from a slightly messy mechanical
 attachment? I can power Logi Bone V2 through a separate supply and may be
 only connect the pins such as ground and Serial Interface for programming
 and remove header where my cape clashes with Logi Bone V2. Any more hints
 or ideas?

 Any help in this will be highly appreciated...

 Hi,

 I want to use MUX1 or MUX2 XIP Boot Mode, 16 bit Address Data

OK. The fix it in Starterware. Be sure an enable the reset function in eMMC
and set the reset line.

Re: [beagleboard] Re: GPMC Parallel NOR boot using BeagleBone Black.

[Gerald Coley]

I meant eMMC can be disabled.allowing for the use of those pins as required
for use with NOR or NAND devices.

And yes, they can be soldered and physically removed as well.

Gerald

 emmc card can't be removed. Did you mean SD card has to be removed?

 Sysboot will ensure that BOOT-ROM will setup the peripheral/pinmux rightly
 to boot from that medium. But after the OS starts it might have its own set
 of pinmux which needs to be set rightly to access that medium.

 cheers,
