hello!RL78/F13 debugging connection E1 prompts an error as shown in the figure. After rewriting the flash memory without permission and disconnecting E1, it is found that the target MCU is not working. Can you please explain the reason? E1 connection did not enter debugging mode and the option to rewrite flash memory was not enabled
Hello,
There is was not a loaded image in your message, please attach it.
Have you tried to connect with Renesas Flash Programmer ?
Can you clarify what you mean by ' After rewriting the flash memory without permission and disconnecting E1' ?
Hello, as shown in the picture
Can you check your 'Permit flash programming option' on debug settings ?
The option to allow flash programming can be turned on, but it will erase the flash memory. I need to read back the flash memory. The problem is that the chip seems to have been erased before debugging
There is not a read operation for flash on RL78 devices so reading back the flash contents is almost impossible for security reasons.
Only chance is to read back the binary symbols and that is only under certain circumstances. Please see below:
