uClinux Boot problem

Hi hippo,

Thank you. But now, I want to implement booting uClinux under IDE, then I will try to do it under Linux. I will ask you question later.

I retry booting without U-Boot, just follow Microtronix's Quick Guide, it is OK.

Next, I try with U-Boot. I follow the step

Build U-Boot and download to flash 0x0

Use vmlinux.bin -> mkimage(not gzip) -> bin2flash(location=0x50000) -> download

Use romfs.bin -> bin2flash(location=0x200000) -> download

Run
