The embedded linux on ebony(440GP) saga continues: - ELDK in place (check) - kernel compiled (check) - u-boot compiled (check) - ebony in place (check ... dip switch settings confirmed) - BDI2000 in hand (arrived this morning)
OK, I'm trying to program flash with u-boot (I'm using u-boot.bin). I am using the 440GP config file provided by abatron, plus the [FLASH] parameters from the example in the bdiGDB users manual for programming flash on the 405. It looks like the memory map as it pertains to flash as well as the part (AMD29F040) was consistent from the 405 --> 440, so it seemed logical to use these FLASH values. The 440GP config file provided does not have any FLASH parameters set, which is why I made this change. Well, I successfully erased the flash from 0xfff8000 - 0xffffffff and checked the locations after the erase ... they were all 'F's. I then tried to program the flash with my u-boot.bin and got the following: ===== start of bdi clip ===== BDI>prog 0xfff80000 u-boot.bin bin= Programming u-boot.bin , please wait .... # Programming flash memory failed at 0xfff80000 BDI>prog 0xfff80000 u-boot.bin bin Programming u-boot.bin , please wait .... # Programming flash memory failed at 0xfff80000 BDI> ===== end of bdi clip ===== Any ideas why this failed. Attached is my config file. I'll just attach the [HOST] and [FLASH] sections to make it a little easier on the eyes. For anyone familiar with BDI sample 440GP confile file, you will see that it is this file with the [FLASH] additions I mentioned above. Actually, after looking at the file, I remembered that I also trimmed information in the [HOST] section ... specifically stuff that was presuming path to Windows information. My host is Linux. ===== start of config file ([HOST] and [FLASH] sections) ===== ;bdiGDB configuration file for IBM 440GP Reference Board -- cut -- [HOST] IP 172.16.77.151 ;Linux host ;FILE u-boot.bin ;FORMAT BIN ;START 0x200000 LOAD MANUAL ;load code MANUAL or AUTO after reset DEBUGPORT 2001 DUMP dump.bin ;Linux: dump.bin must already exist and public writable [FLASH] CHIPTYPE AM29F ; flash part = AMD29F040B CHIPSIZE 0x80000 ;The size of one flash chip in bytes (0.5MB) BUSWIDTH 8 ;The width of the flash memory bus in bits (8 | 16 | 32) WORKSPACE 0x000040000 ; RAM buffer for fast flash programming FILE u-boot.bin ;The file to program FORMAT BIN 0x00000000 ERASE 0xFFF80000 ERASE 0xFFF90000 ERASE 0xFFFA0000 ERASE 0xFFFB0000 ERASE 0xFFFC0000 ERASE 0xFFFD0000 ERASE 0xFFFE0000 ERASE 0xFFFF0000 -- cut -- ===== end of config file ( with cuts) ===== -- Brian ** Sent via the linuxppc-embedded mail list.
