We have using renesas part R5F100FE in our product from long back.
We have received complaint from different sites regarding units is not working.
After our investigation, we found the Code flash is corrupted in "R5F100FE" controller.
Same complaint we have received from different 3-4 site.
After reprogram .hex file unit working fine.
We have read the code flash from Faulty unit with healthy unit and found some area of Code flash is corrupted.
Please give some solution for the same.
Were you able to determine what's causing the memory to be corrupted? What kind of product or application did you use the R5F100FE?

As FrankL said
"Yes, if the emulator session is started the emulator issues a reset to the device and start debug initialization. In this initialization debug information is being programmed. as described in the RL78/G13 manual. Most important, the reset vector is rewritten for the monitor software. So after connecting the emulator the application cannot be used anymore."
You stated that on the boards you are having problems with they reset into a debugging session. Is it possible that these units had an emulator session opened after they were flashed?
