On NXP reference board based on LS1043A SOC we are not able to secure boot using Bank 4 (selected via CPLD). It fails and shows that it is in non secure mode (when reading status registers). But the same procedure works fine and we are able to successful secure boot from Bank 0.
We do have a system requirement to be able to sometimes boot from the alternate Bank 4.
Is this a limitation of the CPLD/reference board or LS1043A SOC? Or is there something that may not be documented in the NXP documentation?
