i want to wite an IAP bootloader  for K20(refer to an2295sw). I can erase program flash sector and wirte a long word into program flash sector. but if i sequentially write several long bytes. it will cause Resetting the chip. In fact, when i earase a program flash sector ,it cause resetting too.

 

(I operate FCCOB registers using Program Section Command and Program Longword Command)

 

Thanks in advance,

yuting.
