The error is literally in the screenshot you posted. "Cannot open .../npk_sh7051" . You specified a bad

there might be some other problem. The path I indicated I copied and checked

It is not so important. SH7051 I have read. In two different ways. The dump is correct. But I can’t find the right xml in order to parse this dump

@ Micharl2831

There are multiple errors, did you not read them ?

1-

Code:

Invalid device, see list with "setdev ?"

setting proper device will be necessary for reflash. Also convenient for dumping , means you don't need to specify ROM size since nisprog will know.

2-

Code:

nisprog> setkeys 0x7B472BD1
Now using SID27 key=7B472BD1, SID36 key1=8F7577FC
nisprog> 0x7B472BD1
Unrecognized command. Try "help"

You formatted the setkeys command wrong. So of course SID27 fails and it falls back to the "slow" dump method.

I tried to give it another SID KEY , in which case the kernel is recognized, but slow reading continues. Subsequently, the rom reader does not recognize the kernel

the filename you've shown is "npk_sh7051.bin" . That is not the same as "npk_sh7051".

This is a npk file, just ported to a more usable command line

In the event that you have a more suitable 7051, I would be very grateful.

Hello.
Got Nissan Leaf JDM ZE0 2011. For short drivings. It's fully electric powered car.

ECU is Hitachi SH705828. Rom readed by Nisprog with "slow dump" method.

Nisrom gave me SID keys:

With setkeys command, Nisprog started the kernel)
I was able to fast dump my rom.

But, with test write... Errors ((

I don't know how much clearer I can make nisprog's "practice mode".

It says right there,

Code:

reflashing (dry run). Note, some harmless write verification errors WILL occur if there are modified blocks

Oh, sorry about that :oops:

I was just afraid to brick my ecu, if it will be really erased, never tried Nissan flashing.

SergArb · **Posted:** Tue Jul 18, 2023 5:19 am

Flashed successfully, thank you for that great tool!

To the statistics on double 7051 cpu . Today, the full UMPUL dump successfully flashed in the y34 neo vq30det ecu. AG901 TO AG900.

Can anyone help me understand what it is im supposed to do with npkern, ive found the github repo and my understanding is you download/copy all the files/directories to you pc and then run combineall.bat but i dont see a way to copy everything without going thru amd doing it one at a time im on a chromebook so im using linux terminal but I also have wine to run .exe programs(but i dont believe that allows me to run a windows command window, or im just a newb and dont know how)
