Petalinux 2018.2; picoZed-7020; Linux kernel unable to bring up second CPU (SMP is enabled). Kernel log:
The same thing was with pz7020_fmc2_2017_4.bsp. Ready binaries from this bsp is unable to bring up second cpu on my pz7020 board. Is there way to fix this problem?
The second CPU is working on zedboard 7010 but not on microzed 7020 after kernel 4.xx! Avnet please fix that bug, I need the second core too!
For some reason bit 7 in the efuse status register is set. Highly likely this is AR65240 case. Older versions of kernel does not check this bit.
I don't think this is the root cause of the problem, this topic says it meet the efuse criteria: http://zedboard.org/content/efuse-integrity
Did anyone observe this on the 7010, or only on 7020?
