[U-Boot-Users] Flash erasing problem

[Takács Áron]

Hi,

first of all I wish you all a happy new year!

I am using a PXA270 based board with u-boot 1.1.2. I'm trying to write an ext2 
filesystem image to flash (I want to mount it read only). First I erase the 
sectors, and I get no error messages. But when I try to copy the image into 
the flash, I get the error message:
Copy to Flash... not erased at 00480000 (ffff0000).
Could anyone please help me in solving this problem? Thanky you very much!
