How to rollback my BOOTCFG register ?
I am using LM3S9B92 microcontroller. In one of my application I have committed BOOTCFG register to some pin to access Rom bootloader. According to stellaris documents, if BOOTCFG register is committed once, I can only go back to previous setting using "Recover Locked Device" sequence. Is there any easy way to uncommit this register or is there any provision in LM flash programmer so that I can roll back my BOOTCFG register (NW bit in BOOTCFG reg) to previous setting. I have gone through Recover Locked Device" sequence in LM3s9b92 datasheet, but didn't understand it properly.
A Debug Port Unlock, under the 'Other Utilities' tab, in LMFlash performs this sequence for you.
Give that a try.
Sorry for late reply...I have tried what u said...and now its working fine...Thanks :)
