Hello, I am debugging my custom board with J-link debugger. The board has nRF52832 as MCU and the power supply is 2.5V. When I debugged the nRF52832 with J-Link, it failed and the error showed " Vtref = 0.000V". But I check the Voltage on the debug port and the voltage is 2.5V. I followed the manual and use the 20-pin connect cable.
Pin 1 connected to VCC on board. SWDIO connected to Pin 26 of nRF52832, SWCLK connected to Pin 25 of nRF52832, and GND to GND on board.
The error is shown below.
How can I debug the problem? Thanks
