I bought the OSD from following vendor :
Had problem connecting the OSD v2.0 to PC via FTDI cable. I supplied 5V to the FTDI connector and 12V to video side. After connecting to PC, the PC can recognize the OSD at the COM port, but after clicking READ in the configuration tool, the error message says “FAILED TO TALK TO BOOTLOADER”, though I pressed the RESET button, it did not help.
I have had 6-7 Minim OSD V1.0 and enough experience to configure V1.0, but this is the first time I try V2.0. The OSD board works fine when connected to APM (with default setting shown on monitor).
Pls advise what did I miss?
