Problem:
I’m trying to write Nec RENESAS V850 D70F3632 with xhorse vvdi prog after Erased and Unlocked. Config and P-flash writing with no problem, but D-flash I can’t write, give me Write Error (00). If I try to write an FF dump, all writing is good. I can change only the first 4bit, and write. Tool VVDI-prog. 5.3.2.
Does possible to write this Nec after unlocking?
Solution:
VVDI Prog can only read MQB NEC35XX RENESAS V850 D70Fxxxx mcu, cannot write mcu.
Same as RH850 mcu, vvdi key tool plus can only read, cannot write.
