My board is very similar to at91rm9200ek but using a 8MB cfi flash AT49BV642D. When barebox started, the flash info as blow: # devinfo cfi_flash0 CFI conformant FLASH (16 x 16) Size: 8 MB in 135 Sectors AMD Standard command set, Manufacturer ID: 0x1F, Device ID: 0xD6 Erase timeout: 8192 ms, write timeout: 256 us Buffer write timeout: 64 us, buffer size: 4 bytes Sector Start Addresses: 10000000 10010000 10020000 10030000 10040000 10050000 10060000 10070000 10080000 10090000 100A0000 100B0000 100C0000 100D0000 100E0000 Barebox said the device id is 0xD6, But it should be 0x1D6. Because of this wrong ID, In function drivers/nor/cfi_flash_amd.c:flash_fixup_atmel() the erase region were reversed. So I can't erase the first few sectors I think it should use read8 or read16 according the portwidth like u-boot does. Am I right? -- Best Regards, zzs _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
