J-Tag Unlock RH850 - Community / Debugging - Lauterbach Support

0
i'm using RH850F1L, I have locked the J-tag, i know the 16Bytes of J-tag key, if i use SYStem.Option.KEYCODE it's not unlocking, i'm getting Debug port fail. i used key in the form of Big-endian method.
Example, J-tag Key 01020304 01020304 01020304 01020304
SYStem.Option.KEYCODE 04030201 04030201 04030201 04030201

i'm using LPD4 method 14Pin J-tag connector, and i tried to change the Debug port method LPD4 to J-Tag also, still the same error.
