Linux Compile Notes

grymoire · November 17, 2023, 1:01pm

I was able to download and build the firmware under Linux. Some notes which might be useful to others… After downloading the repo, I typed

  cd BusPirate5-firmware
  mkdir build
  cd build
  cmake ..

There were some compile errors - “Illegal Character” in the *.pio files.
These files had <carriage return><line feed> terminations (Windows format).
I solved this by typing

  sudo apt install dos2unix
  dos2unix *.pio
  make

And it compiled with no errors.
I then held down the bootloader button, plugged in my BP, and copied the *.uf2 file, and success. I connected to my BP by typing
screen /dev/ttyACM0 11520
The firmware revision was identical to the zip file the bot posted.
Thumbs Up!

Thanks for the info! I’m glad you go it going.

I pushed an update to the line endings in pio files. I’m surprised it didn’t cause issues on the build server - it is ubuntu.

Git client can be configured to change line ending between \r\n and \n. Perhaps in CI/CD their client is just properly configured

I compiled on 2 Ubuntu PCs and I didn’t have any errors either!!! Thank you @grymoire

Hi @grymoire

Do you see something incorrect there?

It looks very similar to my build. I have an older GCC compiler (GNU 10.3.1) and I have a warning you do not have. I haven’t tested a lot yet. are you having trouble using the firmware?

Drakelive · December 7, 2023, 8:08pm

No, no problem, I have updated my BP5 several times by compiling like this and I am enthusiastically testing it step by step.
I was amazed that there were problems that I hadn’t noticed and that the compiler didn’t point out.
I posted the compilation step just to be safe in case someone saw something wrong with it.

grymoire · February 8, 2024, 1:24pm

I updated from the Git and in build, when I type make, I get

That is a pico function in “hardware/dma.h”, which is included in scope.c.

I pulled main and make clean without errors. Maybe cmake needs to be run again? Also, check cmakelists.txt to ensure hardware_dma is included with the stdlibs.

Hmm. hardware_dma is there. These are the steps (it’s repeatable)

 git pull
 mv build build0
 mkdir build
 cd build
 cmake .. 
 make

And these are the errors and warnings I saw

I get a similar error during make bus_pirate5_rev10

I don’t see the string dma_channel_cleanup anywhere except for the file build/CMakeFiles/bus_pirate5_rev10.dir/display/scope.c.obj
Perhaps it’s a library issue? I’m running Ubuntu 22.04.3 LTS

HI @grymoire grymoire
Are you sure you are in the main branch? Maybe you have some changes made but not released?
Last night I repeated the compilation on my Ubuntu 23.10 PC to verify what you described.
I downloaded the repository again to have a clean project but I didn’t have any problems:

git clone https://github.com/DangerousPrototypes/BusPirate5-firmware.git
cd BusPirate5-firmware
mkdir build
cd build
cmake …
make

No problem

If you’re having errors about busy wait, maybe it’s your SDK or environmental variable pointing to SDK? The build server is also Ubuntu 22 LTS, I don’t recall any tricks to get it going (unlike windows…).

grymoire · February 9, 2024, 12:07pm

This is what I did, with a fresh clone. I suspect one of my libraries is out of date.

grymoire · February 9, 2024, 1:13pm

Hmm. I’m using the lastest pico-sdk (1.5.1) from github, and PICO_SDK_PATH
is set to that location.The missing library is there, but it doesn’t seem to be in the BusPirate build.

grymoire · February 9, 2024, 1:52pm

I think I found the problem… Rebuilding.

ian · February 9, 2024, 2:04pm

Great! Please keep us updated.

grymoire · February 9, 2024, 2:08pm

Fixed. I had thought pico-sdk was installed correctly. My mistake.
I needed to also do (in pico-sdk)
git submodule update --init
to update the tinyusb library.

Glad you got it going. Thanks for sharing the solution.
