I have a G120 module on a custom board and earlier today the G120 module lost all the application and seemingly too, the firmware and would only boot as a serial port device.
I am using Tera Term to reprogramme Tinybooter but I get a FileTransfer Finished Successfully and the BL Is shown in the output window. The online docs indicate that this is an error.
No matter how many times I try to update Tinybooter it will not work.
This was the same file I used the other day to update the same module.
What else can I check?
