I wander, if I could ask you a question Wolfgang.

Of course you can. You just did.

I am trying to load uboot 1.1.4 directly into a parallel flash on a board similar to 91rm9200ek. I have written a driver, and the loading to flash occurs perfect without errors. However, I have a problem, after the board resets. Once uboot 1.1.4 loads, it crashes. I believe that the Environment variables are being saved and overwritten by uboot. I am experiemnting with settings, but I don't know the solution yet.

U-Boot does not automatically write to flash memory, only on behalf of user commands.

Here is what I do:

Load uboot into ram Execute uboot from ram Load uboot into flash

This is a different image of U-Boot, one configured correctly (i. e. for booting from flash)? Otherwise see the FAQ: http://www.denx.de/wiki/view/DULG/CanUBootBeConfiguredSuchThatItCanBeStarted...

Reboot Uboot loads to prompt and crashes

Well, debug the code. Obviously your port / configuration is broken.

Sorry to bug, but I don't have anywhere else to go,

Well, you *also* posted on the mailing list.

Best regards,
