Hallo. I have this problem with primary flash programming (IAP procedure). When i erase the flash and start programming it, when i am finished, in about random time some breakpoint in code occures (which cannot occure logically in any way) , and the meory i see is filled with 0x67,0x27 bytes - entire memory. Flash document show this as error flag on - erase timeout occured. But if i do step by step - the erasure and programming occurs correctly. And after it gets finished - in some timeout (5 min?) , the same scenario occures... Perphaps anyone could have a guess? Thank you.
