build openocd on cm4:

sudo apt update sudo apt upgrade -y sudo apt install git build-essential libtool autoconf texinfo libusb-1.0-0-dev libftdi1-dev libhidapi-dev pkg-config -y sudo apt-get install pkg-config libjim-dev -y

git clone https://github.com/openocd-org/openocd.git cd openocd

./bootstrap ./configure --enable-bcm2835gpio --enable-sysfsgpio make sudo make install

test read/write nrf54l15 - does not work yet

sudo openocd -f ./raspberrypi-swd0.cfg -f target/nordic/nrf54l.cfg -c "init" -c "reset halt" -c "mdb 0x00000000 2" -c "shutdown"
