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 -----Ursprüngliche Nachricht----- Von: Ahmad Fatoum <a.fatoum@xxxxxxxxxxxxxx> Gesendet: Freitag, 7.

After the update at Boot nothing happens.. no output on serial. > Devicetree and Configuration (barebox.config in ptxdist) looks fine...got anyone suggestions for me? 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!
