THANK YOU Tom, i know this document "Adding Flash Devices to an EPPC Flash Programmer",i had read it. But in the flash programmer of codewarrior IDE version 5.9.0 ,there is S29GL256N in flash configuration page. so, i think it needn't add flash device for S29GL256N. i want to know whether improper initialization file result in this error "Initialization Failed". i used the init file: "8349ITX_init.cfg". in the board of 8349ITX, there are two flash chips, 8M&16bit. but in the board of my, there is only one flash chip, 32M&16bit. another different of two board is the type of SDRAM: 8349ITX is DDR, my board is DDR2. i only modified the flash module in the init file,SDRAM module have not modified. did this result in this error? i must modified all of the different modules in the init file?
THANKS!
look forward to you help!
