Hi,

it's possible to erase and rewrite page0 from internal program ? I disable before all IRQ, after erase the page0 and rewrite it. But after erase, the program crash (jump to unknow address) . There is a special way to do this ?

Sorry for my english

I'd imagine you'd want to relocate the vector table, and any active code into RAM, and once you have that running, then you could erase the FLASH pages. I'm not sure ''disabling the interrupts'' is going to be adequate.
