Skipping TinyUSB dual examples

[approxdec]

g'day.
why - having done git submodule update --init for the sdk
do i get this? in particular the TinyUSB available at ...
but then Skipping TinyUSB dual examples, as TinyUSB hw/mcu/raspberry_pi/Pico-PIO-USB submodule unavailable

this apprently makes \pico-examples\build\flash\program\flash_program.uf2
not work

regards
joe

no reason why that should be. Pico-PIO-USB is a submodule of the TinyUSB submodule, so you have to initialize that separately (better than doing a full recursive init of TinyUSB which is huge)

cd into lib/tinyusb and do a git submodule update --init hw/mcu/raspberry_pi/Pico-PIO-USB

but then as I say this should have nothing to do with flash_program

[kilograham]

I think this is solved

[Sod-Almighty]

This is not solved. I got this same error today, and git submodule update didn't fix it :(

The problem is in the CMakeFile.txt:

if ((NOT CMAKE_C_COMPILER_ID STREQUAL "GNU") OR CMAKE_C_COMPILER_VERSION VERSION_GREATER_EQUAL 11.3)

[kilograham]

What compiler are u using; previously you had

The C compiler identification is GNU 10.3.1
-- The CXX compiler identification is GNU 10.3.1

Right now, the Pico-PIO-USB code doesn't compile cleanly on GCC 11.3 or above. This will require a bump of both Pico-PIO-USB and TInyUSB to fix.

[kilograham]

by solved, i meant the issue was known, but re-opening so we can track getting this fixed upstream (the GCC version issue)

I'm running on Alpine Linux, because I'm a masochist I guess. I had to install gcc and g++ explicitly.

[kilograham]

yeah, i mean the workaround for now is to use GCC 11.2 or earlier

[Sod-Almighty]

But GCC 12.2.1 does compile the code. If you fix the error in src/pio_usb_device.c that is.

(Missing #include "pico.h")

[kilograham]

yes, but that it is the project Pico-PIO-USB which is a dependency of TinyUSB, which is a dependency of the SDK... we can't just fix it; we have to wait for it to be fixed upstream.

[Sod-Almighty]

Seems kinda an inefficient state of affairs. I wonder how anything gets done at all!

Personally, I'd clone the upstream repos, fix the problem, do a pull request – and if it wasn't actioned in a sensible amount of time, put the working files into my project directly instead of having a dependancy.

[Sod-Almighty]

At the very least, I'd put a note on the front page saying "edit this file, add this line and it'll work". You know, rather than the current situation, where anyone running an operating system newer than a certain date is completely screwed.

[holmbuar]

@kilograham where can we track the issues upstream?

[holmbuar]

For anyone struggling with this issue, I made this work by combining the solutions from both contributors in this thread.

1. Go to tinyUSB directory

cd <PICO DIRECTORY>/pico-sdk/lib/tinyusb

and do a

git submodule update --init hw/mcu/raspberry_pi/Pico-PIO-USB

2. add the line #include "pico.h" in the file

<PICO DIRECTORY>/pico-sdk/lib/tinyusb/hw/mcu/raspberry_pi/Pico-PIO-USB/src/pio_usb_device.c

[lurch]

where can we track the issues upstream?

I'd assume you want to look at https://github.com/hathach/tinyusb/issues and https://github.com/sekigon-gonnoc/Pico-PIO-USB/issues

[kilograham]

Pico-PIO-USB is already fixed and included in TinyUSB master, however TinyUSB master is otherwise broken atm on RP2040
(I made hathach/tinyusb#2151 which needs to be merged)

Once that is done we need a small fix here to pick up a new change from hathach/tinyusb#2150, and at that point develop/ branch of pico-examples/pico-sdk should work if you also upgrade the TinyUSB sub-module to master, or use PICO_TINYUSB_PATH to point at your own local copy.
