We have designed a custom board using the STM32F103R8 processor. It uses the SWD pins for connecting to the debugger. We have a Ulink2 debugger. We are able to connect the Ulink2 to the USB port but the constant message is TARGET NOT FOUND. We have tried a number of things that we have read about on the net. But nothing seems to work. Could someone please help?
We start with the STM32CubeMX to create the basic application. It is set for SERIAL WIRE DEBUG and the Target IDE is the KEIL uvision MDK 5. We can see the code in the HAL area saying NO_JTAG_SWD. But we get the same error. Even when we write the test software in KEIL, we get the same result. Getting desperate now! Please please help!!!
Tough to answer, as this is a customized board.
1. Make sure that your ULINK2 is fine, by:
- following this Troubleshooting Guide: www.keil.com/.../ulink2_trblshooting.htm
2. See and compare the ULINK2 Target Connectors:
