UBoot Config file: at91rm9200dk_config At fist, I compiled the uboot with at91rm9200dk config, but it halt after boot and without prompt. It's work after I add some definition in the file include/configs/at91rm9200dk.h like this: ---------------------------------------------------------------------------- #define CONFIG_ENV_OVERWRITE #define CONFIG_SKIP_LOWLEVEL_INIT #define CFG_ENV_IS_IN_DATAFLASH ---------------------------------------------------------------------------- I think this is very confuse for a uboot user, it waste me many time to find out the correct way to make it work, I think it should be with a simple define to make sure if you boot from dataflash. The good message is my board can show uboot prompt now, the bad message is when I try to erase the DataFlash, it shows error like this: ---------------------------------------------------------------------------- *--------------------------------------* DataFlash[15Mhz]:AT45DB642 Nb pages: 8192 Page Size: 1056 Size= 8650752 bytes Logical address: 0xC0000000 *--------------------------------------* 1: Download Dataflash [addr] 2: Read Dataflash [addr] 3: Start UBOOT [C0008000 => 20000000] *--------------------------------------* Enter: Load UBOOT from dataflash[c0008000] to SDRAM[21f00000] PLLA[180MHz], MCK[60Mhz] ==> Start UBOOT U-Boot 1.1.4 (May 8 2006 - 20:12:59) DRAM: 64 MB Atmel: Flash: 0 kB 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> erase c0020000 c0027fff Error: start address not on sector boundary U-Boot> ---------------------------------------------------------------------------- Does anybody know how to solve with this?

Right answer (I hope): you dont need to erase dataflash. AFAIK, dataflash erasing is performed by driver when you write into dataflash. So, for example, to download binary into c0042000 dataflash "virtual" address, you can use simple "cp" command, without issuing "erase" command first, like this: loadb 21000000 <sending image 0x12345 bytes long by kermit> cp.b 21000000 c0042000 12345 -- With best regards, Andrey Vasilyev ^ permalink raw reply [flat|nested] 4+ messages in thread
