Hi,
Using the WTCDB tool, I am able to program the 8269 board, access flash etc. But, on setting SWB SP successfully
(set swire master speed: tcdb sp 10
set swire slave speed: tcdb wc b2 10
TC32 EVK: Swire OK
Total Time: 0 ms),
the tdebug window shows NO USB DEVICE. Please suggest the possible reasons for the same.

It means the burning evk is not connected with PC, you can change a usb port or PC. If every time is the same problem, may need a new wtcdb tool.

I am able to program the device in wtcdb tool. The device not getting detected issue happens in tdebug and BDT tools.
