CC3220SF: CC3220SF

Part Number: CC3220SF
Other Parts Discussed in Thread: UNIFLASH

Hello,

        I am using TI controller CC3220SF for the development purpose. When I flash code through the Uniflash 6.3.0 in production Mode.

the controller behaves properly. but when i want to debug the application code in CCS 10.2 in debug mode gets the following Error.

Error connecting to the target:
(Error -1170 @ 0x0)
Unable to access the DAP. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK).
(Emulation package 9.3.0.00032)

I tried to flash the code in Development mode from the Uniflash software. and then tried to debug the code from the CCS 10.2 but the same Error Persist. 

I have configured the Target configuration for cJTAG (1149.7 ) 4-pin standard mode. with default frequency 5.5 MHz.

ANY solution to resolve this issue will be appreciable.

    Hi,

    Error -1170 is expected when device is at production mode (JTAG is locked from security reasons). For debugging from CCS need to be device at development mode. This can be done by Uniflash. Was you able to switch device into development mode via Uniflash? Do you use own hardware or LaunchPad? In case of you are using own hardware, was your design revised by TI (e.g. proper connection of SPI flash and JTAG, etc.)? Do you have set correct SOP mode?

    Thanks Jan,

    Yes I am using my own hardware for developing Application. As per the suggestions I tried switching to Development Mode for CC3220SF 

    in Uniflash also flash application and service pack in Development in Uniflash. programming of Both was successful. but when i debug from 

    CCS 10.2 it gives the Error -1170. Don't know where Issue lies.

    Also SOP pins are configured for using JTAG 4 wire connections. 

    I am using the XDS110 Debug Probe for Debugging.

    Hi,

    It is likely a some design issue with your hardware. You should continue with hardware review - SIMPLELINK-WIFI-DESIGN-REVIEWS. But if you meanwhile insert here part of your schematic with JTAG and how XDS110 debug probe is connected, I can quickly check it.
