Resetting readout protection blocks SW programming.

We have set readout protection in a computer, and now we want to reprogram it via SW. Even though we have set the Cortex target driver setup to Erase Full Chip, it will no longer allow us to write to...

Flash Programming Error in Block: 0x00000 - 0x00000

I've put together a very simple circuit using a uPSD3433EV and am trying to program it for the first time with minimal code using the ULink adapter. It seems to pass the Flash+PLD/ACR erase stages but...

I am using a P89C51Rd+ from Philips. I have been testing my software in this microcontroller.But last night with no apparent reason it stoped to erase the block 0 of the FLASH.It simply does not erase...
