RL78F12 Reflash issue with E1 Emulator

I have a board with Micro RL78F12 and I am using the E1 Renesas emulator to program it with the software.

I found that first time I flash the board while it is empty (No SW), the erasing and the flash are OK. Unlike when I try to reprogramm the board a second time, it does not work and I got the following error message.


A framing Error occured while receiving data.

I dont know exactly what is the issue because I should be abla e to flash or reflash the Micro using E1 emulator from renesas?

I tried to change the baudrate of the LIN and any others options but still same issue!
