Will no longer compile for Micropython

ilium007 commented 1 year ago

I know this probably isn't the right place to ask but I would like to do some prototyping in Micropython using an RP2040 / MCP251863 on a custom PCB I am designing (to control over 70 clock faces using stepper motor boards). I have no need for the canhack code and wondered if I can modify to remove all the canhack stuff.

kentindell commented 1 year ago

Yes, there's a build option to cmake choose what to include. Have a dig through the cmake file.

ilium007 commented 1 year ago

Great! I'll check it out!

I have spent a few hours here this morning trying to compile on MacOS... Micropython v1.18 blows up on mpy-cross make:

I'll build a linux VM and try there.

Micropython v1.18 didn't compile on Debain 12 either:

This could be related to the version of gcc:

gcc --version
gcc (Debian 12.2.0-14) 12.2.0

I can't even build the stock Micropython firmware (step 4 in this repo's build instructions):

You have to get a recent Arm gcc, and you have to do that by downloading directly from Arm (they removed their repo from which you could install via a Debian package manager).

Yes... tried that!!

I built a new Debian 12 VM and performed steps below. I can now get all the way through to building the CANPico firmware but hit this same error (I can now build stock firmware on this machine):

Aside from the compile issues I have, I'm still unsure how to compile without the canhack toolkit:

"The CANHack toolkit is a proof-of-concept toolkit of different CAN protocol attacks, showing the viability of low-level bit-banging attacks on the CAN protocol itself."

I would like to make use of the CAN library for sending canbus data without any need for the canhack code (I'm trying to use as little memory as possible) and I am trying to design a RP2040 based board using the MCP251863 with integrated CAN controller and transceiver to lower component count.

I had a look at the CMakeListys.txt as directed but I can't see how to remove the canhack code altogether.

The code below seems to include it by default when running: cmake CMakeLists.txt -DCAN=1 -DCANPICO=1

if(CAN OR CRYPTOCAN)
    list(APPEND MICROPY_SOURCE_PORT
        ${PROJECT_SOURCE_DIR}/canis/canhack.c
        ${PROJECT_SOURCE_DIR}/canis/rp2_canhack.c
        ${PROJECT_SOURCE_DIR}/canis/rp2_can.c
        ${CANDRIVERS_SOURCE_LIB}
    )
    list(APPEND MICROPY_SOURCE_QSTR
        ${PROJECT_SOURCE_DIR}/canis/rp2_canhack.c
        ${PROJECT_SOURCE_DIR}/canis/rp2_can.c
    )
endif()

This was after changing /home/xx/micropython/ports/rp2/machine_pin.c (mcp2517fd_irq_handler has been changed to mcp25xxfd_irq_handler) due to the error below:

I have a build for v1.20 of MicroPython (with Pico W WiFi support) and I'll push it out to here shortly (I'm hoping to roll the new CAN FD drivers in to it - they're written but need testing).

ilium007 commented 1 year ago

I am keen to know how you compiled it! I still can't get v1.18 to build!

kentindell commented 1 year ago

I found the git submodules to be awkward: it's trying to keep many things in sync, and the Pico C SDK has its own TinyUSB. And I found some irritating USB header problems as a result. Can you get v1.20 to build? It's a twisty maze of cmake files, but it should build (on Ubuntu for me).

ilium007 commented 1 year ago

Thanks for looking at it. No, I wasn't able to get v1.20 to build either.

ilium007 commented 1 year ago

No luck on building yet...

any updates on the latest version @kentindell ?

I got one to build with the master branch of micropython, but my c is a little bad so i would prefer an official version.

kentindell / canhack

Will no longer compile for Micropython #21
