Nissan LCN1 - dump of front panel flash memory

**Thinner** · 31st May, 2017, 01:05 PM

Hi,

is there anybody out there who can give me a full dump of Spansion S29GL064 flash on the backside of the front panel pcb of Nissan LCN1 unit?
I would prefer a dump of unit 7 612 830 076 with main software version E603, but all other dumps are welcome too, the more the better.
Maybe someone can give me both dumps, from main pcb (S29GL512) and front panel pcb (S29GL064) of the same unit.
I know there is a JTAG header on the front panel pcb and i've figured out the pinout (see picture below), but i have no practical experience with JTAG nor i have the equipment.
Any help is highly appreciated.

I have 7 612 830 094, I'll try to read later.

Sorry, the panels are different

Hi dmitr511,

thanks for your efforts, your board is version 0420G01-LA6, same as mine.
Only real difference i can see is missing ADV7181C, so what do you mean?
Even JTAG header is in the same place. Please give it a try.

What's the problem? Maybe I have 3 units here. but no Adapter to read the Flash on the Front-Panel. IF you really need it, i will do it by soldering to an adapter-board.
Often, the BGA have bad solderings on these units. Maybe this is your problem, not the software.

Hi,

thanks for your answer. I don't have a hardware problem, my LCN is running fine

But i'm really interested in the firmware and to get the whole picture i need the front panel dumps. So, if you could provide some dumps, you are welcome

But only if it's not too much work for you. Maybe it can be done by JTAG without desoldering, but my hardware knowledge is very limited.
