build firmware on RPi4

[OJthe123]

After installing litexcnc, litex and oss-cad-suite I am not able to get the builder running.
I installed litex and oss-cad with the '--user' option

Which command did you use to install the tool chain. Could it be the 32 bit version is installed, while bookworm is 64 bit?

just
litexcnc install_toolchain --user

https://github.com/YosysHQ/oss-cad-suite-build

there it is said, that arm64 is supported

EDIT: stupid me....raspberry os is not like "regular" PC...i downloaded the linux-arm64 package from the release page and now it works 😄
