I am using OpenOCD with Raspberry Pi 4 to flash the PineTime dev kit. It worked for a day properly. I tested bluetooth and LCD example code using Zephyr RTOS. But all of the sudden it stopped working.
What I noticed when connecting SWD wires the LCD backlight turns on and also when putting the back cover (no SWD connection) the motor starts vibrating. Is it short-circuit? What should I check? Investing the OpenOCD debug log (below) it seems chip is not getting acknowledged.
