Re: [beagleboard] Ethernet LED constantly on and it doesn't boot
Thanks for the tip Gerald. Although it doesn't work. I downloaded the latest flasher image (BBB-eMMC-flasher-2013.09.04.img) put it on a SD card and tried holding down the boot button. But if I hold the button down, no user LEDs turn on. Just the power led. If I leave the SD card with the flasher image in and power the BBB up, 3 of the 4 user LEDs light up and nothing happens. Any more ideas? Or do I just own a fancy black paper wight?

[beagleboard] Directly writing to the eMMC through the expansion header?
tl;dr After trying to get my BBB to update or boot from the microSD card, I mistakenly attempted to remove the MLO file from the eMMC partition, thusly bricking my device. I want to attempt to use the exposed eMMC pins in the header to directly write to it and reimage the flash. Possible? I have been trying for the past couple weeks to get my BBB to boot from the uSD slot, doing a variety of button holds (boot, reset+boot, etc), using a variety of power supplies (initially tried usb, upgraded to beefy 5V10A), and a variety of images (Angstrom, Ubuntu, Debian, both flasher and boot). After unsuccessfully getting it to boot into the uSD card, I attempted one forum post which suggested renaming the MLO so that it would force it to use the uSD. Unfortunately, that has not worked, and now I am left with a brick. Debug serial is a dead line, and it will not boot to anything. Before I give up on it completely, I want to try one more thing: using a second micro, writing a hardware imaging script which will interface to the eMMC directly, reflashing it back to a default state. My questions are this: Will this interfere or cause problems with the processor? Is the eMMC locked by the processor, requiring the use of the password bits to enable write mode? Before I start down this road, what are the means for booting from the serial or USB connections? -James -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] Re: BBB boot when connected to other devices
Do you have a schematic you can share? I suspect that you are clobbering the eMMC pins as they share the GPMC signals. You may want to take a look at the schematic and see what else is connected to those pins.You will also need to boot form the SD slot in this mod as the eMMC is not longer usable. This is just a guess. I f I could see the schematic, I could be bale to tell for sure.

Re: [beagleboard] Directly writing to the eMMC through the expansion header?
The processor connects to these pins, so that will be an issue. The eMMC is not locked by the processor. I would not attempt this as it is likely to damage the processor. The reflashing process that we have on the support Wiki should reflash it. You need to make sure you follow all the steps exactly. http://www.elinux.org/Beagleboard:Updating_The_Software There is a USB and serial boot mechanism, but currently there are no tools available to support this. Gerald On Wed, Nov 13, 2013 at 7:27 AM, James McIlhargey jgm.req...@gmail.comwrote: tl;dr After trying to get my BBB to update or boot from the microSD card, I mistakenly attempted to remove the MLO file from the eMMC partition, thusly bricking my device. I want to attempt to use the exposed eMMC pins in the header to directly write to it and reimage the flash. Possible? I have been trying for the past couple weeks to get my BBB to boot from the uSD slot, doing a variety of button holds (boot, reset+boot, etc), using a variety of power supplies (initially tried usb, upgraded to beefy 5V10A), and a variety of images (Angstrom, Ubuntu, Debian, both flasher and boot). After unsuccessfully getting it to boot into the uSD card, I attempted one forum post which suggested renaming the MLO so that it would force it to use the uSD. Unfortunately, that has not worked, and now I am left with a brick. Debug serial is a dead line, and it will not boot to anything. Before I give up on it completely, I want to try one more thing: using a second micro, writing a hardware imaging script which will interface to the eMMC directly, reflashing it back to a default state. My questions are this: Will this interfere or cause problems with the processor? Is the eMMC locked by the processor, requiring the use of the password bits to enable write mode?

Re: [beagleboard] Ethernet LED constantly on and it doesn't boot
Well, if the MMC is corrupt, it's corrupt. There are no buttons you can press to solve that problem: you have to reflash. Holding down the reset button only prevents corruption in the future.

Re: [beagleboard] Re: BBB boot when connected to other devices
OK. It is confirmed. You are using the pins that go to the onboard eMMC. 1) Disable eMMC in the UENV.TXT file 2) Only boot from uSD. 3) Make sure the FPGA does not drive those pins until cleared by the processor, after the eMMC has been reset.

Re: [beagleboard] Re: BBB boot when connected to other devices
Good. So make sure you pres the boot button to force the uSD boot. You have stuff hanging off the eMMC that is most likely confusing the processor. Even if you disable it, it still tries to boot from eMMC because until l the SW is loaded and running it cannot put the eMMC into reset per the uENV.txt file. This is why I said to hold off driving those pins until after the SW is running. In addition the lower part of P8, that is the boot pins. DO not interfere or use or drive those pins until after the processor has booted. It will mess up the boot order. Do not enable the FPGA until after the processor has booted.

[beagleboard] Re: DT overlay for GPIO output pin -- default state=on / init-high
I am also having problems setting an outpit pin HIGH, even though
everything else is working.
Here is an extract of my DT overlay:
...
fragment@1{
target = pruss;
__overlay__{
status = okay;
pinctrl-names = default;
pinctrl-0 = pruicss_pins;
pins_1{
pin-names = PRU:pin_11, PRU:pin_12,
PRU:pin_13;
gpios = gpio2 13 0
gpio1 23 0
gpio3 4 0;
};
You will notice I have pin-names instead of gpio-name. It all appear
correctly when I am printing the /sys/class/gpio. However, nothing changes
when I try adding *init-high;*
Please let me know if you have found a solution.
On Thursday, October 10, 2013 2:55:02 PM UTC-4, smith.wi...@gmail.com wrote:
I have created a device tree (DT) overlay file based on the examples in
/lib/firmware for a GPIO pin to be used to control a relay that powers a
peripheral. As long as the GPIO is output/high the relay is closed and the
peripheral has power, So consequentially, I need the GPIO pin to have a
default state of high as soon as possible after BBB is powered up.
Everything seems to work (after disabling HDMI!), but I don't seem to be
able to get it to set the pin state to high by default. I'm loading the DT
overlay via the uEnv command line, but it seems that until I manually go
and export the GPIO pin and set the direction to high in /sys/class/gpio,
the initial state of the pin stays low until explicitly set high.
I handle the pinmux as follows:
fragment@0 {
target = am33xx_pinmux;
__overlay__ {
my_gpio_pins: pinmux_my_gpio_pins {
pinctrl-single,pins =
/* the gpio pin(s) */
0x0B4 0x0F /* P8 42 GPIO2_11: lcd_data5.gpio2_11 | MODE7 | OUTPUT */
;
};
};
};
And add it as an OCP as follows:
fragment@2 {
target = ocp;
__overlay__ {
my_gpio {
compatible = gpio-of-helper;
status = okay;
pinctrl-names = default;
pinctrl-0 = my_gpio_pins;
/* declare your gpios */
my_relay {
gpio-name = my_relay;
gpio = gpio3 11 0x00; /* gpio3 is gpio2 */
output;
*init-high;*
};
};
};
};
Shouldn't the init-high cause the pin to go high as soon as the DT
overlay is loaded? If not, how do I accomplish this? I realize I can
write an rc script to export the gpio and set direction=high, but we're
probably talking 10 seconds after power up before that happens.
I have also tried using default-state=on in the my_relay{} section which
doesn't do anything either.
Finally, a question -- the gpio-name of my_relay, what is this for? I
kind of assumed it would be an alias in the /sys/class/gpio tree to gpio75,
but I don't find any references to my_relay anywhere in the /sys/class
tree (or even in dmesg output for that matter).
Thanks!

If anyone is having a problem with their audio cape quality try applying

Hi,
Darren has been working on restoring support for the audio cape, this
is done by reworking the HDMI support patch. There is nothing wrong
with the audio cape or the support for it in mainline 3.8, it is the
patch that adds support for HDMI on the beaglebone black that was
implemented in a way that didn't take other audio peripherals into
account. Darren has reworked this and sent an updated HDMI patch that
restored audio support, but he wanted to do some more work on it
before considering it done. Haven't heard since then, I'll ping him
and check if he is still working on it.

Hi Rowland Up to now you did not tell us that you use 9V for motors that consume maybe much more power than a BBB. If you Project is a little Segway or robot car where it is okay when the battery is down after 20 Minutes or so, then go ahead with the 7805. You can solder this together even without PCB.

[beagleboard] Re: musb_host flushing issue
Okay, I realize that this is tricky and a bit of a unique issue, so I understand if there aren't solutions out there. More basically, then: how can I find the drivers/usb/musb/musb_host.c source file? Maybe I'm thinking about this wrong, but if that's throwing a warning, why can' tI find it anywhere in the file system to troubleshoot?

If I reboot the BBB, I can send the command and get the expected response back, but, again, only once. Other USB issues I've seen discuss power, and my device is bus-powered, but I don't think it's a power issue, as I found the following in dmesg, which doesn't seem to relate to power (this message appears after the first time sending a command to the device, and every time thereafter): WARNING: at drivers/usb/musb/musb_host.c:125 musb_h_tx_flush_fifo+0x35/0x5c() Any ideas on how to troubleshoot this?

Re: [beagleboard] Unable to access PWM from userspace on BBB
Neils, I completely agree with your comments on there needing to be a C/C++ equivalent to the bonescript. With beaglebone 3.8.13, I am able to successfully control a PWM actuator following Mark Yoder's example: (http://elinux.org/EBC_Exercise_13_Pulse_Width_Modulation), almost exactly the procedure Michael Vernier posted above. However, it will only work after I run a bonescript analogWrite() on the PWM pin. It took some digging to reverse engineer the \bonescript-master\node_modules\bonescript\index.js::analogWrite() to determine what it is doing that afterwards allows me to successfully use the PWM device. The analogWrite sets the PWM polarity to zero during the configuration of the PWM: fs.writeFileSync(pwm_test+'/polarity', 0); A similar operation from my C++ side resolved my issue and allowed me to use the PWM device successfully: system(cd /sys/devices/ocp.2/pwm_test_P9_21.14; echo 0 polarity); -Shaun On Friday, May 3, 2013 4:27:20 PM UTC-5, nne...@gmail.com wrote: Thanks a lot.

[beagleboard] Re: Can't get BeagleSNES to work on BBB
Hi Andrew, thanks for responding. 1. Yep, about 800mb, got the full image. 2. Yep, on my 32bit Win 7 system using 7-zip to extract. 3. With the imaged card in the BBB, nothing mounts, at all. I get lights dancing, but nothing. 4. I tried with and without the boot button down, multiple times. I felt like I was being safe about setting this thing up too. I have an anti-static mat at my bench and everything. It is new and this is one of the first things I'm trying with it. I just tried to run android and that did not work either (BBB_JB_Android_3_8_13.img). Now I'm wondering if the board is busted. The steps seem very easy and clear to me. Something just isn't working. I'd rather not spend another $45 to find out its software or my setup. If I have the image written to the card, plug it in the BBB, and try booting it with the default setup, what will the screen look like on the TV? What will happen if I boot without the controller attached? Will booting work with and without the boot button held down at power up? When should I be letting go of the boot button at startup? Thanks again for taking anytime to address my questions.

We can use I2C-tools and file I/O thru /dev/i2c but the read speed is disappointingly slow. We only read the 3x gyros and 3x accels (each one byte at a time plus the 2 byte temperature reading) and it takes ~2msecs. My estimate of the I2C bus cycles for a block read suggests this should take ~160 bus cycles or .38msec on a 400MHz I2C bus. You are running at 400kHz, not 400MHz, right? I2C doesn't do 400MHz. The distribution includes the Invensense driver inv-mpu6050.ko but there is no indication that reading through /dev/i2c invokes it. This is a very popular IMU and Invensense widely distributes the driver over many Linux platforms. The driver source includes “successful installation will create two directories under /sys/bus/iio/devices” and lists the files there (aka functions). I can never get these to show up. I can “insmod /lib/modules/3.8.13/kernel/drivers/iio/imu/inv_mpu6050/inv-mpu6050.ko” and “echo inv-mpu6050 0x68 /sys/class/i2c-adapter/i2c-1/new_device”.

I have some specific needs, did some google searches but couldn't find anything useful so I decided to ask here. 1. I have a Python application that access and reads some data from a HID device (Tested, works) 2. I need to simultaneously flicker 2 LEDs (15-16Hz, not much) through GPIO using transistors 3. I may need to use the PRU for offloading the LED part if Python + switching LEDs hog the CPU (Which was sometimes the case in Raspberry Pi) 4. I don't need HDMI or any other physical capes. 5. (Problem*) I need scipy which needs BLAS and ATLAS. Those libraries needs a fortran compiler but no fortran compiler is available in angstrom repositories. Any suggestions? Is this use-case OK for another distro with much more packages like debian or ubuntu? Are they stable enough?

Re: [beagleboard] Hardware info on USB A port

However, my point is that I ran the same software on both a normal computer and the BeagleBoard. On the normal computer everything works fine while on the BeagleBoard-xM the device starts to oscillate. Back to the normal computer, it works fine again. Now assuming that all LS/FS/HS USB specifications are the same, how can this happen? Any suggestion on what I can be missing that is not the same ? Please try an oscilloscope. That's a good suggestion. Have to find one. hvn Well, between a normal PC and a BeagleBoard, the only things that change are: the compiler, the processor's architecture, the processor's clock speed, the memory interface, the caches, the peripheral's connection to the processor and the interrupt architecture. If you are expecting no influence from those changes, you need to wake up. :-( :-( Oh, I'm wide awake and do know it's a RISC board and thus different. But despite that, an ordinary mouse, keyboard and webcam work well. if you consider Sparc (RISC as well)...not an ordinary computer either, but mechanical devices are proven to work. So being different in architecture doesn't mean it can't or won't work. Still looking for an oscilloscope.
