Dear chi l,

What is the purpose of the _POST_WORD_ADDR variable in include/post.h? How should I define the value of that variable?
See post_word_load() and post_word_store() [both in include/post.h] how _POST_WORD_ADDR gets used. You need a persistent (across resets of the CPU) non-RAM memory cell.
Also, I try to run the post_memory_test in normal mode, before relocation ( the test verifies only small 4Kb regions of RAM around each 1Mb boundary). That seems to work. But when I tried to change the value of the regionfrom 4K to 8K, it does not work anymore. Does anyone have a clue on that ?
You are aware that you must not (under no circumstances) be executing this code from system RAM? It can only be run rom a memory device that is not currently being tested (parallel NOR flash, SRAM, OCM or such).
Best regards,
