AFAIK nobody (either Atmel) uses u-boot stored at the beginning of the flash (as many others ARM board producers do), but AT91 uses a pre-bootloader. FYI, I have ParallelFlash: AT49BV1614A DataFlash: AT45DB642 Any help will be appreciated TIA

As with every ARM based board, ok I wondered why Atmel used a so tricky boot methos instead of using only u-boot ;-) YEAH ! Now is perfect (except for a weird CRC error message: U-Boot 1.1.3 (Sep 30 2005 - 15:33:58) U-Boot code: 21F00000 -> 21F172AC BSS: -> 21F1B968 RAM Configuration: Bank #0: 20000000 32 MB Atmel: AT49BV1614A (16Mbit) Flash: 2 MB DataFlash:AT45DB642 Nb pages: 8192 Page Size: 1056 Size= 8650752 bytes Logical address: 0xC0000000 Area 0: C0000000 to C0007FFF (RO) Area 1: C0008000 to C001FFFF (RO) Area 2: C0020000 to C0027FFF Area 3: C0028000 to C083FFFF *** Warning - bad CRC, using default environment In: serial Out: serial Err: serial U-Boot>

Wolfgang, thank you for answering. I have done as you suggested, but now the board don't boot (I am going to install the old u-boot) I don't understand why the default configuration for at91rm9200dk is don't work on my board, after 3 days I'm still unable to use 1.1.3 :-( BTW the u-boot.gz I am sending here is created with gzip-ping u-boot.bin These are the commands I've done: Uboot> loadb 20000000 ...SEND BOOT.BIN... ## Ready for binary (kermit) download to 0x20000000 at 115200 bps... ## Total Size = 0x00002908 = 10504 Bytes ## Start Addr = 0x20000000 Uboot> cp.b 20000000 10000000 5fff Copy to Flash... done Uboot> protect on 10000000 10005fff Protected 3 sectors Uboot> loadb 20000000 ...SEND U-BOOT.GZ... ## Ready for binary (kermit) download to 0x20000000 at 115200 bps... ## Total Size = 0x0000b9a9 = 47529 Bytes ## Start Addr = 0x20000000 Uboot> protect off 10010000 1001ffff Un-Protected 1 sectors Uboot> erase 10010000 1001ffff Erase Flash from 0x10010000 to 0x1001ffff Erasing sector 8 ... ok.
