Hi,
I have a problem with IAP for ST72521. I am using the IAP driver available from ST site. I always get ''Operation Failed'' status flag from ECMD. Initially through inDART i am setting option bytes as ''Disable read out protection'' I am using a External Chip Oscillator of 16 Mhz and my Fcpu is 8 Mhz. I am following the below sequence with watchdog disabled: RASS Disable (56 & AE as keys) Sector Erase (sector 1) Toggle a port pin if successful Infinite loop Could someone throw some light what could be the reason for this? Thanks in Advance, Sarav2005-01-29 10:09 PM
I wanted to clarify a few points regarding my previous problem.
I have the probelm with Flash Erasing(sector 1) itself. St72521 is a HD flash device. I have verified that my device is not damaged due to overcycling , by writing some test code into sector1. I am attaching my Metrowerks project for reference. I have configured my device with option bytes ''7D B7'' through inDART. I am using ST662A charge pump on my board.2005-01-29 10:16 PM
