Stuck with Flash write and erase (R32C153)

Hi Frens,

I am still trying to perform the flash write and erase in R32C153 controller.

I learned from the forum that the E8a debugger should be in  Debugging of CPU rewrite mode to do so.

But when i use this option these message pops up..

Fatal error: Unknown exception in driver (#E11) 

Please help me to correct this .. I have also tried the other options of E8a debugger, but the the flash erase and write are not working.. There are no errors.

Thanks
