Hi,
I've ported u-boot to my PXA270 board and have it working as a network boot loader. I'm now trying to get flash programming working so I can flash the kernel and root file system. Our board has two Intel 512Mib P30 flashes on it configured as 32-bit memory. The 512Mib parts are actually two 256Mib parts on the same die so u-boot should see two banks of 32-bit memory with two flash devices in each bank.
After booting flinfo shows that u-boot has found four devices but the addresses seem to be wrong. It has
bank 1 0x00000000 - 0x03ffffff bank 2 0x04000000 - 0x07ffffff bank3 0x00000000 - 0x03ffffff bank 4 0x00000000 - 0x03ffffff.
Any ideas where I might have gone wrong? The relevant portions of my board header file are below.
Regards, Justin.
