Issue when built using cmd "make snowy"

[kchinnasamy]

When I try to build the os, I was getting the below error,

System details

No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 19.10
Release: 19.10
Codename: eoan

Please note I'm running window linux subsystem

it looks the arm-cs-tools is out date, not sure.

Yeah, 4.7.2 is truly ancient. Try using gcc-arm-none-eabi from apt, and then use the defaults rather than overriding PEBBLE_TOOLCHAIN_PATH in localconfig.mk?

[ishotjr]

@kchinnasamy the apt version is likely ancient too - I haven't used WSL in a while, but here's my notes from a previous time I set it up:

Manually installed ARM toolchain:

cd ~
wget https://developer.arm.com/-/media/Files/downloads/gnu-rm/8-2018q4/gcc-arm-none-eabi-8-2018-q4-major-linux.tar.bz2
mkdir -p "${HOME}/opt"
cd "${HOME}/opt"
tar xjf ~/gcc-arm-none-eabi-8-2018-q4-major-linux.tar.bz2
chmod -R -w "${HOME}/opt/gcc-arm-none-eabi-8-2018-q4-major"

I tend to have to use a bunch of different versions for different projects so I will often end up just doing e.g. export PATH="${HOME}/opt/gcc-arm-none-eabi-7-2017-q4-major/bin:$PATH" as needed. Anyway, LMK if that doesn't fix it - I have a bunch of Windows machines that I've used for this in the past and a bunch of notes about how I got it working...

Thank you both.

I'm new to Firmware development,

after installing the gcc-arm-none-eabi now I'm getting the below output

% make snowy
VERSION build/version.c
[snowy] CC build/version.c
[snowy] LD build/snowy/tintin_fw.elf
4796 bytes of CCRAM available.
30056 bytes of RAM available for heap.
568156 bytes of flash unused.
OBJCOPY build/snowy/tintin_fw.bin
[snowy] PBZ build/snowy/snowy.pbz

Just wanna make sure if this means the build is successful.

and also I'm trying to run the firmware using make snowy_qemu,

% make snowy_qemu
make: *** No rule to make target 'Resources/snowy_boot.bin', needed by 'build/snowy/fw.qemu_flash.bin'.  Stop.

Am I missing something ?

It looks like you are missing the qemu resources.

If you wish to run the firmware in qemu, copy the resources necessary into Resources/. Take a look at Utilities/mk_resources.sh for more information on that.

Also you will need the fpgas if you don't have them already

You need the snowy_fpga.bin and chalk_fpga.bin files to compile on their respective firmwares. They can be found on the #firmware channel in the Rebble Discord.
