Hello guys! Still I dont read it, has a mcu R5F. First I want to power up, because I dont have the exact km (about 27000) and for test in the bench. Somebody has the connection of +30, +15 and GND?

I have the electrical wiring for the previous version. I attach the pdf in case someone needs it.

Thanks!

Hi all! Today I read the MCu, ia R5F10DPEJ, without any problem. Buy When I want to write the MCU, give "error erase". The connection of VVDI is correct. What could be the problem?

Try to use the read_secured option.

I read with the secured option. Read, and delete the data, and now I cant write the mod file or the oribinal!

:winky: If you can delete then you can also write. Did you tried to put a 2.2kohm resistor between tool0 and vcc?

Yes..... Is very extrange. I put the 2k2 resistor between vcc y tool0. Read perfect, but dont write, gives this error when erase before write, but erase the memory when I read secured option. Search in the forum and any user haves this problem. In a few hours, I put a picture of the connection.....

This is the answer of the xhorse distribuitor:

Hello, please try more times and check the connection diagram all the same like diagram in software
if still the same error
it is not support your type to erase
