Compile on raspberry pi

[dorinilut]

Hello,

Just tried to do a compile of this on a raspberry pi.
System Information is:
pi@rasptv:~/openthread-r21 $ cat /etc/os-release
PRETTY_NAME="Raspbian GNU/Linux 11 (bullseye)"
NAME="Raspbian GNU/Linux"
VERSION_ID="11"
VERSION="11 (bullseye)"
VERSION_CODENAME=bullseye
ID=raspbian
ID_LIKE=debian
HOME_URL="http://www.raspbian.org/"
SUPPORT_URL="http://www.raspbian.org/RaspbianForums"
BUG_REPORT_URL="http://www.raspbian.org/RaspbianBugs"

Followed the instructions and all seemed to be in good working order until running the build. There I got the following message:

`pi@rasptv:~/openthread-r21 $ sudo bash script/build.sh

Am I missing something?

There is no Tooelchain yet to compile the firmware on arm. You will have to compile the RCP-Firmware on x64 for now

[Haerteleric]

hey i just had a look on the available ARM toolchains for the M0+.

Sadly there is only a toolchain for 64Bit ARM Corsscompiler. What version of Pi are you running ?

[dorinilut]

I can switch easily to a 64 bit version. I can do that as soon as I am home. I am on 32 bit version now. I will do that and retry and come back with an update. thank you for taking the time.

[Haerteleric]

I have not pushed the arm64 toolchain yet, cause i dont have hardware to verify at hand atm. Maybe wait till tomorrow or compile it on your main machine (or a x86_64 based VM).

[Haerteleric]

So i updated the bootstrap.sh script to check for the arch of the compiling Host.

I validated on a rpi3 running 64Bit RaspberryPi-OS.

you will have to delete the "gcc-arm-none-eabi" and "out" Folder and rerun the bootstrap.sh before the build.sh.
(Or start from scratch)

sorry for the delay in update. thank you for the update. it did install. now there seems to be a new issue:

any pointers will be greatly appreciated.

It seems like your Debugger is not detected correctly. What kind of Debugging-Tool are you using ?

[dorinilut]

I would very much like to answer your question but unfortunately I cannot say. I think i'm going to wait till there is an official release. unfortunately I was hoping this would be a pretty straight forward process. I can find my way in Linux, but I am not an advanced user, so instead of you guys wasting your time with me it's better if you focus on your development. I'll do some more research on my own.

As far as I can tell I have the openocd as per instructions in the build and it is confirmed to be at the latest version.

I have the same issue as you on an x86 ubuntu VM on proxmox, with my conbee 2 with USB passthrough.
