HI, I have been having trouble getting the RTTT windows tool up and running with a WL1801 on our test board. I can connect and see the below:
But when I try to load the .bin and .ini, it gets ~75% through, seems to poll the Mac FW, and then fails, giving me a Calling_GetFW_Version() returned -13108. And the logs look like this:
I have some questions to help me debug. I am using a 3V3 UART-USB converter with 3V3-1V8 level shifter and all the data looks ok at each point in the system. I can see data coming from the WL1801 back to the UART-USB, but for whatever reason this is not being read correctly. Any ideas?
I have pulled the IRQ line high via a 10k resistor to power up the WL1801 in debug mode. Is this enough to initiate the debug funcionality?
And since I can connect to the unit, should I assume my UART-USB coms bus is working ok and that this is a chip side issue, or is it possible the bus is working for simple commands and falls over at more complex ones?
Any insight you would have here would be much appreciated.
