[U-Boot] u-boot-2010.06-rc3 to AT91rm9200dk

[Rajeesh.R]

Hi,

I have compiled Uboot version u-boot-2010.06-rc3  and I got bin file .

I tried it to download bin file to at91rm9200dk board it stops after
some time witth error .
I think this is due to insufficient of SRAM capability ie 16KB SRAM
uboot size is 107KB
How to download this uboot directly to flash ...location  any other
configurtion in uboot for this . . Wherther Romboot is required ..?


With Thanks

How did you try to load the file to your device?

I think you have chosen the BOOTROM based upload via xmodem cause you
talk about SRAM size which does not matter if you boot from NOR flash on
CS0.

Use an JTAG ... as recommended by Wolfgang
(http://lists.denx.de/pipermail/u-boot/2010-June/073191.html)

You can do it with some effort ... You may tinker an first stage
(bootstrap) loader to initialize your SDRAM and NOR flash which is
sufficient to load the U-Boot via xmodem to write it in NOR flash.
Another requirement for that part of software is to be small enough to
fit in SRAM.
Some people did this before, search google for "at91rm9200 xloader" or
"at91rm9200 bootstrap" but I also recommend to get an JTAG and flash
your NOR that way.

I have answered all these questions previously. Please re-read my
previous postings.
