Cc3220sf & Fatal: CS_DAP: Error connecting to the target: (Error -1170 @ 0x0) unable to access the DAP.

Hi,

I was using my cc3220sf and it was working fine but when I changed a few wires connected to the board while it was working and tried to upload the code (using energia), it gave me this error:

Fatal: CS_DAP: Error connecting to the target: (Error -1170 @ 0x0) unable to access the DAP.

 

Ps1. I have another program on sFlash and when I pluged the usb I didn't wait for that to start working and I just uploaded the new code.

 

Ps2. I didn't change the sop configuration and it's still 010. The device manager can see Both XDS110 class application UART and auxiliary Data port.

I tried to reset the board this ways:

1. Put SOP as 000. Unplug the usb. Press switch 1 and while holding it, plug the usb back. 

2. Put SOP as 000. Unplug the usb. Press switch 4 and while holding it, plug the usb back.

Any recommendations would be appreciated. 

What can I do to fix this?

Thanks 😊
