This version doesn't have E2lite and by using uart connection i receive Error(E1002006) : Invalid Signature reading.

RE: MIB2 hardware fault NEC70F3488A
Update is not writing whole full NEC content as i know just a part.

you need read full content of the original NEC (it is read protected) but its possible to CRACK the NEC the protection to read it over programmer wink

RE: MIB2 hardware fault NEC70F3488A
Bootloader part is written 1:1
He only need that part to get this running.
Normal software update will cover the app part later.

As i said use vendor supplied tools like Renesas CS+, this way you will have 100% success.
Using third party tools like Orange5 or whatever will only make the task harder.

Regards.

RE: MIB2 hardware fault NEC70F3488A
So far i downloaded and installed every tool from Renesas that i could find.

With cs+ i couldn't find a way to send the bootloader through Uart or E2 lite. RFP v3 doesn't have V850 in the list and RFP v2 is giving signature error. I'm starting to think that E2 lite programmer is useless for what i need.

RE: MIB2 hardware fault NEC70F3488A
E2 does not support V850.
No successors to E1 for V850、78K0R、78K0 or R8C* Family MCU Users
So you need either E1 or ... Orange 5 with V850 extension, i have never used the latter.

PG-FP6 also is an option. But all this stuff costs more than the unit is worth. Unless you are going to be fixing this stuff regularly otherwise forget about it.
That said, I can use an MMX board donor....

RE: MIB2 hardware fault NEC70F3488A
After a week of struggling to programm this chip using Uart connection I give up and order Orange5 (is the cheapest option, and probably i will not use this interface any time soon).
Does anybody have a dump for MIB2 Harman V850?
I have to convert V850Bolo from .bin to .hex in order to flash it and i don't really trust this conversion.

RE: MIB2 hardware fault NEC70F3488A
I'm unlucky with this device.... 
I bought Orange5 and is showing the chip as 40f3000. If i try to read or write it i receive errors. 
Bought 2 chips from this seller, both of them showing 40f3000, now i asked for a refund and order another chip.
I attached a screenshot from Orange5:

RE: MIB2 hardware fault NEC70F3488A
Are you trying to program it while it is soldered in the unit? I'm pretty sure the Orange5 will have problems with overriding pull-up/down signals from the rest of the circuit. May have to lift some pins like RESET.

RE: MIB2 hardware fault NEC70F3488A
Yes is soldered because i need the motherboard oscillator crystal for programming and RESET pin is not connected to the motherboard.
