I've tested this patch on a mx51 boards as well and it worked fine there.
Fine, thanks, this saves me time - I will not test it on that SOC.
For testing purposes, can you see if this change helps any? Perhaps the rom isn't loading all the code, and this will load a little more.
I had the same feeling.
In fact, increasing artificially the size with the zdata1 section helps. It boots. There should be an error by computing the total length of the image.
Best regards, Stefano
Oops, my previous test patch was after bss instead of before. With this patch

And those extra 0x100 bytes are garbage, not from the eprom.
