Hi, I succeeded in compiling and running redboot on my lomx-board with an additional AT45DB041B Dataflash. I had to modify my atmel bootloader so it - supports my small dataflash device, (quite simple, changes available at request if someone is interested) - loads redboot at the correct address (0x20001000), (I corrected this value and suddenly it just worked) - and uses the correct PLL settings, but now it works. (you get funny characters on the serial console if the clock settings are not correct and you try to boot linux.)
I used the gcc version of the atmel bootloader (from teest.com, version 1.01). You seem to use version 1.02 of the bootloader. Do you use the ADS compiler or is there also a gcc version of it ? (I use the ecos gcc for the bootloader, too.) I also noticed that the default frequency setting in redboot is at 184MHz. (CYGNUM_HAL_ARM_AT91RM9200_CPU_CLOCK). I thought the CPU would always run at 180MHz ? At least the current AT91RM9200 errata (page 2) says the PLL is limited to 180MHz. I get some timeouts when I use tftp when downloading big files, but not too many. I can not boot the linux delivered with my board, as this uses a ramdisk and thus would require the redboot exec command. I can run it via "go", but of course then I get a kernel panic. But this is not a problem to me as I do not want to use linux here anyway.
