Up to Date Documentation? #83

Open McNugget6750 opened 3 years ago

McNugget6750 commented 3 years ago

Not a software bug in general - but you could call it a documentation bug in general.

I am trying to get the BBB into service, I have never worked with it before, only during the last month or so. After many days/weeks of research I have Python, I2C, and some very basic GPIO working. Why does it take me so long? Because the BBB Debian was changed so much since its release that no tutorial writer could keep up. Every single example about every single device in the BB, doesn't work. There are seemingly no current tutorials. The Adafruit libraries are all deprecated. TI abandoned pasm. Code does not compile for PRUs. Simply blinking an LED takes days of research.

Okey, enough venting. I realize, maybe I'm simply looking in the wrong spot and don't use google well enough for BBB. Where can I find good starting points for the latest BBB image? I'd like to get into PRU coding, I'm experimenting with I2C, GPIO, SPI, and other devices.

Kind regards, Timo

Example, straight from the PRU Cookbook: https://beagleboard.org/static/prucookbook/#_blinking_an_led

@McNugget6750 , that should be fixed via:

sudo apt update 
sudo apt upgrade

if not, please run:

sudo /opt/scripts/tools/version.sh

This is the udev rule that set's that up..

McNugget6750 commented 3 years ago

Thanks for the quick reply, Robert!

I'll try sudo /opt/scripts/tools/version.sh

I know it's not solved by updating. I do that almost every day before I start any work on the BBB.

Cheers Timo

McNugget6750 commented 3 years ago

Unfortunately, it doesn't help. I also tried rebooting after executing the script. Still the same error during compile.

RobertCNelson commented 3 years ago

@McNugget6750 sudo /opt/scripts/tools/version.sh doesn't do anything, it just reports the install setup..

I wrote it for debugging user install, please attach the output..

McNugget6750 commented 3 years ago

I don't know for sure but it looks like beaglelogic is attached to a PRU. I never succeeded installing BeagleLogic, the installer just won't succeed and as a result I wasn't able to capture any data. But here it does look like uboot loads the beaglelogic pru core? Do I have to get rid of that first? How?

1:

bootloader:[eMMC-(default)]:[/dev/mmcblk1]:[U-Boot 2018.03-00002-gac9cce7c6a]:[location: dd MBR]

Let's fix that ^...

sudo apt update
sudo apt install bb-u-boot-am335x-evm
cd /opt/u-boot/bb-u-boot-am335x-evm/
sudo ./install.sh
sudo reboot

2:

kernel:[4.19.94-ti-r42]

Fix that ^

sudo /opt/scripts/tools/update_kernel.sh
sudo reboot

3:

uboot_overlay_options:[uboot_overlay_pru=/lib/firmware/beaglelogic-00A0.dtbo]

Fix that ^

in /boot/uEnv.xt:

Change:

uboot_overlay_pru=/lib/firmware/beaglelogic-00A0.dtbo

to:

uboot_overlay_pru=AM335X-PRU-RPROC-4-19-TI-00A0.dtbo

and reboot...

Then you'll be back to "default"...

McNugget6750 commented 3 years ago

Great support, thank you! I'm a bit surprised because apart from my cape installation for BeagleLogic, this is a fresh installation from the beaglebone website. So all the kernel updates should have been done already. Maybe there is something to be updated in the documentation.

Summary: Your suggestions all worked with no errors and the example compiles now.

@McNugget6750 OK to close this issue?

treedy commented 2 years ago

Resurrecting this bug/FR. I would say, no, it isn't ok to close. Documentation is still severely out of date or incorrect. Even the instructions in this bug have errors. For example, the errors at the end of update_kernel.sh. Is this project active or should the community move on to other alternatives?
