I am having a problem writing with MC loader to a 18f4331 with 20 MHz boot loader. I can write once or twice with no problem then I get the message. a problem occurred trying to write to the following program location. address $000153 , what do you want to do? Cancel. It happens with several addresses. In some cases I can reset and the programmer first erases and then programs a few more times otherwise I can no longer write.
I built the hardware with 16f877 and never saw this problem. Any ideas?
