Hi Felix,
Can U-boot be burned on 460EX based board (using BDI3000) without configuring DDR controller? The BDI configuration file for Canyonlands board on Denx site http://www.denx.de/wiki/view/DULG/Appendix#Section_13.1. has no DDR setup, but also doesn't work on Canyonlands (fails on flash erase). The configuration file from AMCC site does work, but it contains full DDR setup.
It should be possible.
A BDI2000 configuration file flash section looks something like this:
; ================================================================= [FLASH] CHIPTYPE MIRRORX16 ;Flash type: Spansion S29GL256N 32MB CHIPSIZE 0x2000000 ;The size of one flash chip in bytes BUSWIDTH 16 ;The width of the flash memory bus in bits ; (8 | 16 | 32 | 64) ;WORKSPACE 0x1000 ;workspace in DDR RAM FILE u-boot-1.3.1.bin FORMAT BIN 0xfe000000 ERASE 0xfe000000 ;erase sector 0 (128kB sectors) ERASE 0xfe020000 ;erase sector 1
Make sure to comment out WORKSPACE, and the BDI should be able to program the board flash without needing DDR configured.
Cheers, Dave
