Context uninitialized assertion failure in xlat_tables_core for ZynqMP

by Michał Kruszewski

Hello, I want to boot Linux on ZynqMP (XCZU15EG). I follow the standard procedure. I have generated FSBL using Vitis. I have compiled bl31 (tag: xilinx-v2025.1). I have a standard boot.bif configuration looking as follows: the_ROM_image: { [bootloader] fsbl.elf [pmufw_image] pmufw.elf [destination_cpu = a53-0, exception_level= el-3, trustzone] bl31.bin [destination_cpu = a53-0, exception_level= el-2, load = 0x10000000] images/u-boot.bin } However, the bl31 reports the following error during the handoff to u-boot: ASSERT: lib/xlat_tables_v2/xlat_tables_core.c:788 BACKTRACE: START: assert 0: F_FUNCTION: 0x2880 1: F_FUNCTION: 0x4cac 2: F_FUNCTION: 0x2628 3: F_FUNCTION: 0x36e0 4: F_FUNCTION: 0x108 5: F_FUNCTION: 0xfffcd8e8 BACKTRACE: END: assert This is an assertion for context being uninitialized in the mmap_add_region_ctx function. /* Static regions must be added before initializing the xlat tables. */ assert(!ctx->initialized); Does anyone have any idea what might be wrong?
