Im afraid that this test is hiding another errors, because its testing the whole DDR range. And in post/tests.c the flag POST_ROM is set, but
I don't think so. I thiunk you're just misusing the test.
booting from NOR flash SPI we are in DDR since the beginning.
In case it is not obvious: you cannot run a memory test on the memory you are running from. You must make sure to run the POST memory test _before_ relocation to RAM.
So, is there an easy way to fix it when booting from NOR flash SPI? I thought only enabling it in the config file was enough.
I changed POST_ROM to POST_RAM in post/tests.c, but I dont know if this is secure. In the past we executed mtest in the middle of DDR.
Our company says that is mandatory the DDR test in initialization...
Best regards,
