Other Parts Discussed in Thread: UNIFLASH
Hello Community,
I am using CC3220SF on a custom board. The UART commands are sent with UNIFLASH CLI from PC via USB to UART converter to CC3220SF on pins 55 and 57 of UART_Tx and UART_Rx respectively.
The reset on the custom board is controlled with the switch.
To test the UART connection I have used the command for UniFlash Cli flashing
dslite.bat --mode cc32xx project program --name cc3220sf_out_of_box_tirtos --project_path C:\SLImageCreator\projects --port COM21 --dev
After sending a break signal, I reset the device using the reset switch but no response was received on the Tx line of CC3220SF. I am expecting 0xCC here on the line.
I used a logic analyzer to see if the chip is getting a break signal and reset signal, whereas on pin P57 Rx line I could see the break signal and reset signal on the reset line.
I am not sure what is going wrong here, I want to see if the chip is responding at all.
How should I proceed in testing my custom board here to see if Chip is functional or not ?
Thanks and Regards,
Neil
