I guess that's the confusing part. When I run with debug on I get the following log. Halfway down it reports "Now running in RAM - U-Boot at: eff89000", but there are still initcall's to lower memory after that. So I'm thinking lower memory is still used at that point. Am I wrong? I did try a mem test starting at the lowest address and it worked, but I would like to understand why the initcall's to low-mem after relocation. The mem test essentially erases those addresses, so initcall's to those addresses are suspect at that point.

I think the mx53 has internal sram, which is why we were able to run fully from there before, since we had set CONFIG_SKIP_RELOCATE_UBOOT. I tried setting CONFIG_SKIP_LOWLEVEL_INIT, but nothing works with that set. -- View this message in context: http://u-boot.10912.n7.nabble.com/Memory-test-post-relocation-tp196088p196196.html Sent from the U-Boot mailing list archive at Nabble.com.
