This is the purpose of CFG_MEMTEST_SCRATCH.
Please, please read the README, which says:
"- CFG_MEMTEST_SCRATCH:
Scratch address used by the alternate memory test
You only need to set this if address zero isn't writeable"
The last statement implies that you DO need to set
CFG_MEMTEST_SCRATCH if address zero ISN'T writeable.
No need to change any code at all.
Cheers
Anders
