20 years agoHi lucky,
This is very strange -- I've been using u-boot for quite some time without any major problems ... so a few more questions ... I'm sure we'll eventually figure this out: 1. Where did you get the u-boot source code, and when? 2. Did you enable the JTAG UART in u-boot? i.e. -- are you using the JTAG UART for both u-boot and the kernel ... or are you using a serial UART for u-boot and the JTAG UART for the kernel? Also, please try the following with an uncompressed u-boot image file: -- Program the image to flash as you normally do: @ 0004_0000 -- Post the output of u-boot command: ==> md.l 00400040 8 -- Tell us what happens when you try this from the u-boot prompt: ==> go 00040040 This will jump directly to the kernel entry point in flash for an uncompressed image file (the u-boot header is 0x40 bytes long; the kernel binary immediately follows the kernel. Doing this will force the kernel to relocate itself. Regards, --Scott
