Which is your arm-none-eabi-gcc version?

vyrus001 commented 5 years ago

gcc version 8.2.0 (Gentoo Hardened 8.2.0-r2 p1.2)

iceman1001 commented 5 years ago

Looks like the new gentoo arm toolchain creates a too large bootrom image. Stack_chk_guard .. Under the wiki https://github.com/Proxmark/proxmark3/wiki/Gentoo-Linux it states another arm toolchain. Tried it?

fabled commented 5 years ago

I had the same issue. It is because gcc generates PIE executables by default. Add -no-pie to CFLAGS to fix it. And stack protector. So -fno-stack-protector too.

iceman1001 commented 5 years ago

@fabled where do you add this? the bootrom & armsrc makefile? -fno-pie -fno-stack-protector

...ok, tested to add it.
