Start by reproducing the failure on the cvitek duo256m using the master version and compare it with the standard build, which reportedly works. Use the shown boot log and rtthread.elf with addr2line to investigate the reported instruction and load page faults. Done means the smart build boots without the nested trap or page-fault shutdown.
