Thanks for confirming that u-boot is not in MMC. This provides one more step on my path of discovery to writing some raw code to inject into kindle RAM and execute with USB/HID mode.
Well, I didn't confirmed that u-boot isn't at MMC. And I'm not confirming it now. I've just provided one relevant fact.

Also, I think that i.MX50 boot ROM couldn't be reprogrammed. It's a ROM. And I didn't found anything about boot ROM reprogramming at i.MX50 Reference Manual. Boot ROM supports ROM patching, but it's a runtime mechanism, not one-time reprogramming.

Besides, Kindle u-boot size could be not the same as typical u-boot size.
