Hi
Im new to U-boot and need help. I am using U-boot-2009.10 and a MPC8548 board with 512MB DDR and 128Mb nor Flash(using cfi)
I am booting the board using a BDI2000 by loading my u-boot.bin file to the bootregion in my memory map (FFF80000) and running from the reset vector. Uboot starts up and works fine. I am able to unprotected the flash ( confirmed with flinfo) and can erase sectors other than the bootsector. I have placed the output below.
UBoot=> protect off all Un-Protect Flash Bank # 1 UBoot=> erase fff80000 ffffffff .. done Erased 2 sectors UBoot=>
When I look at the erased memory using md the u-boot image that was loaded into memory by the bdi is shown at the bootsector address fff80000 UBoot=> md fff80000 fff80000: 00300030 552d426f 6f742032 3030392e .0.0U-Boot 2009. fff80010: 30312d30 30323236 2d673663 36653034 01-00226-g6c6e04
if i reboot the board not using the BDI the bootregion shows the old uboot image and was not erased.
I think the sram is mapped over the flash boot region and when i try to erase and cp to the bootreagion the commands and date gets lost. Can anyone help me find the problem? thanks Hendrik
