Hey,
today i followed yout recommends with git bisect.
I've found the offending commit.
It is Commit : [b0348d677bb47bdbd368983603b3e9604528d4ed] ARM: Compile with -fPIE
If I remove the Compilerflag (line 145) :
CPPFLAGS += -fPIE
from arch/arm/Makefile , then every Barebox Version (include v2020.01.0) compile and run fine on phycard imx27.
Whats the impact if I remove this flag? Does imx27 not support this option?
Regards
Holger

Try finding the offending commit with git-bisect:
git bisect good v2019.01.0
git bisect bad v2020.01.0
# build, flash, run barebox
git bisect good # if it works
git bisect bad # if it doesn't work
There have been 1004 revisions between the two tags, which means, a binary search will find the offending commit in 10 iterations.
When you've found the commit and need to take a more thorough look (printf-debugging), you can add low level UART debug support to your board.
Keep us updated!
Cheers
Ahmad
