I have been following the Customize BeagleV-Fire Cape Demo and it has been very helpful. Thank you for the work that has gone into it so far.
I am running into a few problems following along:
-
Using the gateware/main branch, my device trees aren’t working like I would expect. If I load a shipping bitfile such as “default”, “robotics” or BVF-0.4.0-27-g7078de9 the devices show up in
/sys/like I would expect i.e. with pwmchipx```.beagle@BeagleV:~$ find /sys/class -iname "*pwm*" 2>/dev/null /sys/class/pwm /sys/class/pwm/pwmchip32 /sys/class/pwm/pwmchip0 /sys/class/pwm/pwmchip16 beagle@BeagleV:/sys/bus/i2c/devices$ ls -al total 0 drwxr-xr-x 2 root root 0 Sep 19 16:50 . drwxr-xr-x 4 root root 0 Sep 19 16:50 .. lrwxrwxrwx 1 root root 0 Sep 19 16:50 1-0010 -> ../../../devices/platform/soc/2010b000.i2c/i2c-1/1-0010 lrwxrwxrwx 1 root root 0 Sep 19 16:50 1-0050 -> ../../../devices/platform/soc/2010b000.i2c/i2c-1/1-0050 lrwxrwxrwx 1 root root 0 Sep 19 16:50 i2c-0 -> ../../../devices/platform/soc/2010a000.i2c/i2c-0 lrwxrwxrwx 1 root root 0 Sep 19 16:50 i2c-1 -> ../../../devices/platform/soc/2010b000.i2c/i2c-1If I build the same “default” or “robotics” cape with no changes using the
build-bitstream.pyscript the drivers don’t load and I see empty folders.beagle@BeagleV:~$ cd /sys/class/pwm beagle@BeagleV:/sys/class/pwm$ ls -al total 0 drwxr-xr-x 2 root root 0 Sep 19 16:50 . drwxr-xr-x 52 root root 0 Sep 19 16:50 ..I double checked the device tree and it does not show the
overlaysdirectory I expect.beagle@BeagleV:/proc/device-tree/chosen$ ls boot-hartid name stdout-path -
To fix that issue I was thinking that I need to build with the CI pipeline as it suggests in a later step. To do that I need to fork the Gateware repo. Unfortunately, the “Fork” option for the Gateware repo is greyed out and disabled.
Should it be available to all users? Or should I request access?
I can click on the number beside the “Fork” button and a new window with a new green “Fork” button shows up. I can add my details, customize the repo name, etc but when I click “Fork Project” it errors out with an unhelpful description.
Thank you again for the help.
