[U-Boot-Users] AT91RM9200 Dataflash op error with U-Boot1.1.4

[KylongMu]

Dear Groups:
	My board contains: AT91RM9200 DataFlash:AT45DB642 (without nand
flash)
	Crosstool: ELDK4.0 for arm
	UBoot:     Get from www.denx.de with git, and update to most recent
code.
	UBoot Config file: at91rm9200dk_config

	At fist, I compiled the uboot with at91rm9200dk config, but it halt
after boot and without prompt. It's work after I add some definition in the
file include/configs/at91rm9200dk.h like this:

----------------------------------------------------------------------------
#define CONFIG_ENV_OVERWRITE	 
#define CONFIG_SKIP_LOWLEVEL_INIT
#define	CFG_ENV_IS_IN_DATAFLASH
----------------------------------------------------------------------------
	I think this is very confuse for a uboot user, it waste me many time
to find out the correct way to make it work, I think it should be with a
simple define to make sure if you boot from dataflash.
	The good message is my board can show uboot prompt now, the bad
message is when I try to erase the DataFlash, it shows error like this:

	Does anybody know how to solve with this?
Thanks a lot!

Perhaps, this patch will help you:

Dear Andrey,
	Thanks for your answer. I patched these two files one by one, or
both of them, but all failed, and the error is still.
Thanks a lot!

Oops... My mistake. I've replied without carefully reading your 
question...
Right answer (I hope): you dont need to erase dataflash. AFAIK, 
dataflash erasing is performed by driver when you write into dataflash.
So, for example, to download binary into c0042000 dataflash "virtual" 
address, you can use simple "cp" command, without issuing "erase" 
command first, like this:

loadb 21000000
<sending image 0x12345 bytes long by kermit>
cp.b 21000000 c0042000 12345
