I have a Cygnal C8051F300 part in which I have used some FLASH space to store adj variables. Since then, I can't download a new program.

1) CDE Message: -> Attempt has made to write to protected bla bla... I select OK to proceed.

2) CDE Message: -> Part or all of memory is protected. This operation will erase... again OK

then comes up 1) again as forever loop

Besides the Target comment shos a C8051F000 instead of F300

PS. I tested with both IDE1.71 and 1.80 and the FlashutilCL without success.

PPS. I also posted this topic at Cygnal.
