ID mismatch error

Hi All!

I'm using Flasher 5 rev3 in order to program Renesas chip M30291FC.

I wrote a simple program and downloaded it into chip. But when i try to program the chip second time i get :

"Error 31: ID mismatch".

What is the problem?

Hi,

Renesas bootloader (target CPU) requires the correct ID. Without it,
you will be unable to access, read out, clear, or program the contents
of the flash memory. The requested ID depends on ID previously written
into the target CPU. For more information, please refer to the section
ID code check function of the CPUs users manual.

Regards,
Til

Hi Til!

But i didn't set any ID, in "Options" > "Passcode" - it's all zeroes.

Regards.

This is also an valid ID. Sometimes when flashing of a device is interrupted you have unpredictable data in flash and also an unpredictable ID code in flash (this is why I don't like the ID code). Please try as ID code the "00 00 00 00 00 00" and "ff ff ff ff ff ff". Some Renesas devices have also a special ID code which tells the device to erase the flash, please have a look in the specific Renesas cpu manual.
