The RL78 family MCU is being debugged using E1 or E20 in the CS+ environment.
When downloading of programs is started, the following message is displayed and downloading is interrupted.
[Direct Error Cause]
Writing to the on-chip debug reserved area is prohibited (address:0x****) (E1203124 or E0204001)
Since "address: 0x****" in this message indicates the address at which the area used by the debugger overlaps that of the user program, the area to which the user program is to be downloaded should be re-examined.
The area used by the debugger can be confirmed from the following:
"E1/E20/E2 Emulator, E2 Emulator Lite Additional Document for User’s Manual (Notes on Connection of RL78) " -> "3.3 Securing of area for debugging"
