Problem:
I had a problem with the xhorse vvdi prog. It failed to read Range Rover velar 2018 Renesas V850 D70F33506 mcu and gave error try frequency failed.
Solution:
1.Follow the wiring diagram here to make a connection. Connect a 1Kohm resistor between RTXD and VCC
2.If fails again, change frequency and try again.
