I am using xmc1300 boot kit CPU-13A-V1 with DAVE 3 for my target board with XMC1302 (infineon) microcontroller.
On some of the boards connectivity is proper and debugging is possible.
However in some boards there is a connectivity issue.

No device found on SWD.
No device found at all. Selecting JTAG as default target interface.
I took the following steps(with same result):
1. Took out the jumper from USB supply and gave a separate 3.3V to the target. There is a provision for this on the boot kit. This eliminates the possibility of overloading of USB supply by target.
2. A fresh processor was soldered on the target.
3. All components were removed from target board except for the uC with SWD interface.
SWDIO and SWDCLK trace lengths are very short. ( No problem with signal integrity)
I am considering purchase of J-link (debug probe). Would this eliminate the problem?
As per Section 1.6 of user manual " Having the intelligence in the firmware leads to improved stability and higher performance."Could this be the cause of SWD communication failure?
Would the J-link probe work with DAVE 3?
Thank you.
