OpenOCD uses a server-client architecture, it is therefore recommended to operate at least two concurrent terminals to the board, e.g. one UART Console and one SSH, or 2x SSH.
Open a third console for interactive debugging to monitor the UART between MCU and Linux.
Take MCU out of reset
The MCU may be kept in reset by GPIO1_IO5 of the Host. Release it:
| Code Block |
|---|
# check status of control gpios (reset, power)
gpioget -c /dev/gpiochip0 5 6
"5"=inactive "6"=active
# release reset
gpioset -c /dev/gpiochip0 5=1 |
Start OpenOCD
