Hello, I have a problem uploading the firmware (VDAPFUL_V3_64.ROM) to VNCL1-1A
1. I use UM232R and Vprog software.
2. Should I connect CBUS0 (VNCL1) to TXD or RXD (UM232), and CBUS1 (VNCL1) to TXD or RXD (UM232)?
3. And the same with RTS and CTS!!!
4. I have tried the all options but I got no results
5. I have connected Prog (VNCL1) to CBUS2 and Reset (VNCL1) to CBUS3
6. Do I have to use Mprog to change any setting of UM232R ??
What is the wrong I did? please help
Sami

    There's a completely different technique for updating the firmware. You download the "reflash" version of the firmware to a USB memory stick, rename the file as described on page 14 of the firmware manual, and insert the memory stick in the device while it's powered.
