- Rebuilding u-boot for Cyrus
- The Cyrus defconfigs are Cyrus_P5020_defconfig and Cyrus_P5040_defconfig.
- They currently disable size optimization in order to avoid a relocation
- bug in some versions of GCC. As the output size is a constant, the size
- optimization is not currently important.
- Cyrus boots off a microSD card in a slot on the motherboard. This requires
- that the u-boot is built for the Pre-Boot Loader on the P5020/P5040.
- In order to reflash u-boot, you must download u-boot.pbl, then write it
- onto the card. To do that from u-boot:
- > tftp 1000000 u-boot.pbl
- > mmc write 1000000 8 672
- If you want to do this via a card reader in linux:
- > dd if=u-boot.pbl of=/dev/sdX bs=512 oseek=8
