Dev notes

CubeIDE recomends user to enable the ICACHE for maximum perfomance.
OpenOCD does not yet support the H5, ST maintains a fork with support.
OpenOCD does not come with udev rules for the new ST-Link V3, here's the required line:

# STLink v3
ATTRS{idVendor}=="0483", ATTRS{idProduct}=="374e", MODE="660", GROUP="plugdev", TAG+="uaccess"
