Does anybody knows how to erase the dataflash which is connected to the SPI? U-Boot1.1.2 > erase c0000000 c001ffff Error: start and/or end address not on sector boundary
Hi, U-Boot does not support dataflash erase. You can emulate an erase by overwriting with FF (yes, it's possible, see below).
The copy of images with "cp.b" to this flash seems to work properly, even without erasing the flash before.
Thats because the Atmel dataflash does not need any explicit erase (see the datasheet for more details).
