We want download the hex file to MCU through USB-I2C/LIN-CONV-Z Evaluation
Boards(you have sent us).
After we connect the evaluation board to the computer usb port and our module ,
we start the I2CWSD(download from your website) software in the computer .
After press the START button in the I2CWSD software, it says that "Please
connect the Dongle to I2C" or "communication timeout".
Could you tell me what reason will cause this happen and what flow should we
follow to download hex file to the 7020?
1) Check h/w connection
2) check if (0x14)=0xffffffff
