I bought a V2.0 Minim OSD from the following source :--
I had problem connecting the OSD to my PC via FTDI cable. Tried 2 configuration tools (minim OSD Extra and Arducam), both did not work. I have owned 6-7 Minim OSD V1.0 , and very familiar with connection to PC.
I applied 5V to the FTDI connector and 12V to the video side. After connecting the FTDI cable to PC, the PC can recognise the OSD, but "FAILED TO TALK TO BOOTLOADER" .
Can anyone help. Thank you in advance.
