Dear Ramesh, i am running last u-boot (pulled yesterday) on a coldfire m5307 and a SST 16bit flash, erasing works fine.
>From your debug trace seems the correct erasing command (0x30) is sent. But the function you mentioned detect that flash is not erased. Are you using a 16bit port for data connection to the flash ? First check i would do is an "erase" test. Try to erase some sectors with "erase" command, something like # erase 40000 4ffff Then dump the memory, (to be sure also with BDM eventually), to see if it has really been erased. Also, these are some settings i am using in my config, maybe they can be useful: /* * Start addresses for the final memory configuration * (Set up by the startup code) * Please note that CONFIG_SYS_SDRAM_BASE _must_ start at 0 */ #define CONFIG_SYS_SDRAM_BASE 0x00000000 #define CONFIG_SYS_SDRAM_SIZE 16 /* in MB */ #define CONFIG_SYS_FLASH_BASE 0xffc00000 #define CONFIG_SYS_TEXT_BASE 0xffc00000 #define CONFIG_SYS_MAX_FLASH_BANKS 1 #define CONFIG_SYS_MAX_FLASH_SECT 1024 #define CONFIG_SYS_FLASH_ERASE_TOUT 1000 /* * CFI FLASH driver setup */ #define CONFIG_SYS_FLASH_CFI #define CONFIG_FLASH_CFI_DRIVER #define CONFIG_SYS_FLASH_USE_BUFFER_WRITE ... Let us know if you find something. Regards, Angelo _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
