LS1043A: symmetric multiprocessor boot fail

TatsuyaSUZUKI — Wed, 08 Jun 2022 10:15:54 GMT

Hi,

I am trying to boot VxWorks 7 on our custom board based on LS1043ARDB.

I have already succeeded in booting VxWorks 7 kernel that is built in uniprocessor (UP) configuration

from nxp_layerscape_a53 BSP from u-boot using LSDK21.08.

However, the error occurs when I try to boot VxWorks 7 kernel built in symmetric multiprocessor (SMP) configuration.

I doubt this cause of error is failure of PPA boot process, because u-boot output log shows “CPU: 4 cores online”.

Does anyone know this reason and how to solve this problem ?

The following is the error log…
