Thanks!

For SDRAM part, do you recall the detail? For example, which register did
you change? Is it SDRAM configuration register (SDRAM0_CFG)?

BTW, a very tough situation I have to deal with is that I don't have a
debugger. I made some software debug tool and tested it on evaluation board
and they all work. I believe the program stopped at early_init() in
head_4xx.S.

Best regards,
Frank
