you can also compile Qt on the target although it will take insane amount
of time. But it will be 100% operational

[beagleboard] android bbb

Hi!

Does anyone know where I can find sources for rowboat android for BBB while
gitorous is dead? I need to compile Android myself but all free
instructions have links to gitorous, which is "migrating" and that
migration continues for ages

Re: [beagleboard] BBB based design w/TPS65217C - Any issues switching between AC and USB inputs if no Battery used?

2015-11-24 Thread Maxim Podbereznyy

you will definitely have random reboots like regular BBBs have it. There
are hundreds of posts here and I am not sure that the issue was solved in
the current kernel. You can't enable 3 power sources at TPS65217
simultaneously, only two of them. You can switch off Vac input, but Vbat is
always enabled. I suppose random reboots will not take place if you
physically disconnect Vac and USB0_VBUS.

Re: [beagleboard] miniPCIe+SIM cape

2015-11-20 Thread Maxim Podbereznyy

it depends on what device you want to insert into a miniPCIe slot. As far
as I know all such form-factor GSM modems are usually USB devices and PCIe
has USB lines

 Yikes ! And my bad I had not realized. Too bad so many of us suckers
 feel compelled to use Windows in the first place. I've been using MS OSes
 since DOS 5, and now . . . I couldn't say what OS I'll be using passed
 Windows 8. For the desktop that is.

Hey guys!

Does anyone know which benefits this sdk provides? I used to use building 
scripts from Robert Nelson, but this SDK seems to offer more flexible tool

 If so that looks like the mmc port is not being probed correctly as it
 is not defined. You should at least get some activity on mmc to try and
 read the type of sd card on this bus. This should identify as a wl12xx
 and then load the drivers when you insmod wlcore_sdio

Re: [beagleboard] Camera solution for industrial use.

It is strange but Google searching works for me:

 Ok, i work over a project about color sorting into food industry with less
 cost.

 I have decided to use Beaglebone Black.
 In order to do the color sorting i will use OpenCV.
 The problem that occurs is the hardware part - the camera.

 As far as google can tell me my only option is a webcam - via usb. (lot of
 options for R-Pi though)
 The program will only take snapshots.
 Than means the time it takes for a snapshot has to be minimum and same,
 every time.

 Could you suggest the best and affordable option?

 Welcome,

 As for the beggining i would like to say tha im new to BeagleBoard

 I`m really curious if it is possible to use external USB hard drive (with

 I tried to follow up those instructions :

Re: [beagleboard] TLV320AIC32X4

I think these regulators are not necessary because you supply them in
hardware anyway. Using dummy regulators is sufficient.

These are the problems to solve:

Re: [beagleboard] Re: RAM 1GB option

The Green is cheaper and it will be the main reason to sell them a lot.
HDMI? Who needs it?

2015-08-19 18:47 GMT+03:00 Maxim Podbereznyy lisar...@gmail.com:

I'm almost sure that 90% of users will be happy staying at 512M without
paying extra 15 dollars for questionable advantage of 1GB. I even doubt the
majority of hobbyists need 512M. If you don't use Xorg then tons of console
applications are happy with 256M of RAM

2015-08-19 18:40 GMT+03:00 Philip Polstra ppols...@gmail.com:

I would like to see the price difference. It would be nice to have a
cheaper board and perhaps a premium board for some things. The upgrade
from 2GB to 4GB on the board doesn't do anything for me since my OS is much
larger than that, but yet only the more expensive 4GB boards are
available. Would hate to see something similar happen with the RAM. The
only reason the BB Green is at all attractive to me is not because it has
the Grove connectors, but because it is cheap and I could use it for my
hacking drones. For the times that I need more RAM the 1GB boards that are
already available are nice.

Re: [beagleboard] Re: RAM 1GB option

Jason,
I just list low-volume prices from Avnet, available without a project
registration. Pretty sure you have a better deal with Micron :)

2015-08-19 18:51 GMT+03:00 Jason Kridner jason.krid...@hangerhead.com:

William,

That sounds like some fuzzy math to me. I don't think a BOM increase
of $15 is a wash with removing the HDMI---and I didn't think removing
the HDMI was even an option to consider for the BeagleBone Black
itself. I do, however, feel Maxim's numbers are for fairly low-volume
purchases and I'd hope we could do better than that.

Regards,
Jason

It will cost more. If Jason approves the cost increase we can make

on a Rev D board.

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

Re: [beagleboard] Re: BBB intermittently rebooting.

2015-08-11 Thread Maxim Podbereznyy

probably you used a wall adapter with integrated monitoring chip which does
not allow to overcurrent 500mA. You should use a dumb version of such
device when it simply supplies as much power as it can :)

2015-08-11 14:42 GMT+03:00 William Hermans yyrk...@gmail.com:

 *you can power a board by USB but from a special wall adapter with an
 integrated USB socket. As an option*


 Yes, and we tried it. It was not enough power. It is also my understanding
 that powering the BBB in such a way can not give more than 500ma. It was
 not enough power. the canbus would not function at all part of the time. As
 soon as I applied power via barrel jack. Then problem went away.

 Hi Maxim,

 The reason why we did this is that the board in question was mounted to
 a piece of wood, that is screwed into a wall. So grounding Vbus would not
 have been easy. Vusb for us was really easy. Solder the outside pins on a
 USB A socket to the outer shielding, then plug a MALE A to mini B cable to
 the socket, and BBB. Took a total of like 5 minutes . . .

 Normally I do not worry about any of this, and use USB power. Except
 this time for this project we needed the canbus running, and powering via
 USB cause the canbus to be less than reliable.

 I was going through this forum to resolve my current problem with custom
 board copied from Beaglebone Black for our company's specific need.
 We are using AM3352 TI cpu and Alliance AS4C256M16D3 MEMORY chip set which
 has tCK 2.5 min 3.3 max.

 Hence, I board memory leveling though CCS 6.1.0  for DDR2, The following I
 noticed
 1/ Jtag initialise and connect cortex A4 memory test seems to succeed
 2/ When I try to set break point hard at s_init() CCS does NOT get set
 breakpoint
 3/ Using Assembly code stepping system reach to following stage

 U-Boot SPL am335x (july 27 2015 16:46:16)
 Incorrect Magic Number (0x) in EEPROM
 Could not get Board Id.
 Unknown board, cannot configure pinmux. ERROR ## Please RESET the
 board 

 AND system hung permanently.

 After setting message and enumerated my structure am335x_baseboard_id
 in the function read_eeprom() the program fall out from lack of magic
 number while reading MLO file
 AS I noticed there were no values in the am335x_baseboard_id header
 structure.

 The question IS this check can be by passed?  Including all EEPROM info
 board name serial SKU etc

 I ran diff on the provided link for the board.c which exists on git repo
 am335x/board.c I did not found any difference.

 If you please shed some light on this problem I am stuck on this almost a
 week.
 Much appreciated for your  help.
 Thank you,

 Imran K

  The board console seems to be /dev/ttyUSB1.

 Your answer is right 

 So you 'cloned' a BB, did you also set the internal eeprom id?
 Probally not..  So rebuild u-boot and bypass this check, for what
 you've actually installed on the board for memory.

Re: [beagleboard] BBB intermittently rebooting.

You can disable in software Vac or Vusb, but not the battery source, that
is why so much trouble

 Because of the reason that BBB is a universal enthusiast's board all three
 power sources are left floating, which contradicts with tps65217
 architecture. We figured out that if the most of users use only a barrel
 connector or USB then Vbat input should be grounded. I don't know if this
 solution fixes the random reboot issue but at least it complies with the
 TPS65217 architecture. Probably anybody should try to ground the Vbat input
 and see how the board behaves.



 I was reviewing the TPS65217 datasheet and I think this may be the area of
 concern (from section 9.3.9.1):

 The linear charger periodically applies a 10-mA current source to the BAT
 pin to check for the presence of a battery. This will cause the BAT
 terminal to float up to  3 V which may interfere with AC removal detection
 and the ability to switch from AC to USB input. For this reason, it is not
 recommended to use both AC and USB inputs when the battery is absent.

 Since the battery is absent for most BBB users, TI recommends using AC or
 USB power, but not both.

 Furthermore, the TPS65217 has internal sinks on the AC and USB inputs, so
 it should not be necessary to short either input to ground when it is not
 used as long as the input sinks have not been forced off by the software.

 9.3.9.4 AC and USB Input Discharge



 AC and USB inputs have 90-µA internal current sinks which are used to
 discharge the input pins to avoid false detection of an input source. The
 AC sink is enabled when USB is a valid supply and VAC is below the
 detection threshold. Likewise, the USB sink is enabled when AC is a valid
 supply and VUSB is below the detection limit. Both current sinks can be
 forced OFF by setting the [ACSINK, USBSINK] bits to 11b. Both bits are
 located in register 0x01 (PPATH).



 NOTE [ACSINK, USBSINK] = 01b and 10b combinations are not recommended as
 these may lead to unexpected enabling and disabling of the current sinks. 9


 Perhaps someone can check if these are being set to something other than
 00b.

I could in my archive messages:

I can confirm that the pulsing detected by PMIC on USB_DC signal is the
probing from USB-OTG.



After I disabled the USB-OTG in the kernel, the system has never rebooted.
Btw I also re-loaded Angstrom image (3.8 kernel) and Andrew's Android image
(with 3.8 kernel). I did not observe USB-OTG probing pulses on the VBus. I
believe in the 3.8 kernel, the USB-OTG has not been implemented/enabled.
That might be reason why it seems that 3.8 kernel doesn't have the random
reboot behavior.

 http://www.deutronic.com/products/power-supplies/ac-adapter/esc15g-15-watt.html
 Average reboot number of each BB-B was each about 3 per day.

 After reading this thread, I simply connected a USB cable from the front
 side Type-A to the back side Mini-USB and since then the number of reboots
 drastically decreased, within the last 12h I saw in total just two.
 Other systems under my control but not located in my lab are showing the

 Robert:

 I can also confirm the behavior of rebooting on +5V Barrel power, and no
 reboots when on USB power.
 Same hardware, same OS/Software, running on +5V barrel input reboots about
 three times per day,
 randomly.  Same-same on USB power (iPhone 1A charger, no USB activity) has
 been running without
 reboot for almost two days, now.

 I can also confirm that this reboot problem does NOT exist in 3.14. I have
 Debian 8.1/kernel 3.14
 that have been running for multiple weeks on +5V barrel power, without
 reboot.

 There have been some significant recent changes to USB power that allow
 tablets to both push
 power out of a connector to power thumbdrives, etc, as well as take power
 in the SAME connector
 for battery charging.  It is a kludge of a system if I have ever seen
 one.  You might want to see if
 any of this new USB power code has affected things.

Re: [beagleboard] BBB intermittently rebooting.

2015-07-20 Thread Maxim Podbereznyy

As far as I remember how the Vbus issue was described in details, hope I'm
not mistaken:
Vbus connects to both CPU and PMIC. CPU has a charge-pump circuit to detect
OTG devices (inject some power and track USB signals for incoming events)
and it injects 5V periodically into Vbus line. Sometimes PMIC detects this
5V on the Vbus input as a good voltage and turns inner power switch to Vbus
where in fact no 5V with sufficient current. Next power failure and
immediate reboot occur

 You never said what you were trying to do with the BBB, and why you need
 Debian 8.1/kernel 4.x.x.
 As you have seen, it is temporarily broken, but is being worked on. This
 is a test release, and not recommended for active use, unless you like
 adventures, like you are having.

 If you need the capemanager, consider Debian 7.8/kernel 3.8

 If you don't need the capemanager, but need some other benefit of Debian
 8, then use Debian 8.x and kernel 3.14.

 Both of these options are solid, do not reboot by themselves, and don't
 care whether it is powered from the 5V barrel connector or USB.

Re: [beagleboard] My BBB does not work anymore

It should not get damaged because PMIC should handle voltage up to 20V as
written in its manual.

 Not knowing what is damaged, I would say replace the processor. If the LED

 Or you can request an RMA.
