Hi, I'm using the Mass Erase command on the Flash from a bootloader running in RAM. There are no errors reported, and the Erase Verify command also gives the appropriate 'Erased' feedback. However, the Flash content remains unchanged!?!?
 
If I use the same sequence of instructions via the BDM, it works as it should. Are there timing issues that are not listed in the data sheets?
