Linux+freeRTOS for rpi4 - Error: junk at end of line, first unrecognized character is `1'

[landgraf]

Tried to build using arm-gnu-toolchain-11.3.rel1-x86_64-aarch64-none-linux-gnu and arm-gnu-toolchain-12.2.rel1-x86_64-aarch64-none-linux-gnu. For whatever reason "linux" expands as "1" and fails to build

@landgraf, sorry for the delay in the response, and thanks for raising this issue.

I believe the issue here might be due to the fact you are using the "GNU/Linux target (aarch64-none-linux-gnu)" toolchain instead of the "bare-metal target (aarch64-none-elf)" one. Could you check if switching the toolchain solves your issue? Or if you have come up with some solution, describe it here?

@landgraf any feedback?

gcc binary is not part of the aarch64-none-elf but make expected to see one:

@landgraf Once again, sorry for the (huge) delay. I can't tell what is happening, as I'm sure that makefile uses the full triplet binary name (i.e., aarch64-none-elf-gcc) as long as the environment as the correctly defined CROSS_COMPILE either with the /path/to/toolchain/bin/aarch64-none-elf or just aarch64-none-elf if the toolchains bin directory is in your PATH environment variable. Actually, the makefile just assumes the latter if CROSS_COMPILED is not defined in the environment or passed as a make argument.

I used an older version of Arm GNU toolchain (gcc-arm-11.2-2022.02-x86_64-aarch64-none-elf), and it worked.
