The difference is caused by ENDIAN issue. Anyway, I will
consider it
carefully.
Oops? Can you program your flash for exanmple with a BDI200?
Hardware issue. I can program it with BDI2000, PowerTAP and UsbTAP under CodeWarrior. Any suggestion?
Please explain. When the BDI can program the flash, the CFI driver should be able to do the same. What exactly is the problem?
mpc7448 processor is BIG ENDIAN, while the tsi108 bridge connects the flash chip by little ENDIA mode. When I set __LITTLE_ENDIA in the cfi_flash driver, everything seems OK, but the written bytes are swapped (see the following log). Now, It seems that if I define CFG_FLASH_USE_BUFFER_WRITE in my config file, this issue can be solved. I will do more test on my board. While, how can I set __LITTLE_ENDIA mode for cfi_driver file in a BIG ENDIA system? Thanks.
