Once I start using sam7 util, the bootstrap code has not been executed which means the SDRAM has not been initialized. I'll have to added the lowlevel init to do that, which I might try if nothing else works.
You don't understand:
- flash all arm9load & u-boot
- loady <address> u-boot-mod
- go <address>
I'm tying this method. I had to go to kermit because I never had suscess loading serially with minicom. I had problems with kermit in the past but couldn't remember what it was... until now. I've always had fatal errors after a few bytes are transmitted. I get some error, then it tries to resend but had too many errors. I'm not really sure how to get past this as I'm configured the serial line accordingly. Is this a common "user error" problem with ckermit? I've double checked my config option with uboot docs.
I have used "minicom" a lot when downloading to the AT91RM9200, but I use the special downloading program which I found somewhere and included in the U-Boot-1.1.2 found on buildroot.uclibc.org.
Did you try programming from Windows using SAM-BA?
