It would be extremely helpful to see how semihosting and itm works with this crate

[DoumanAsh]

For example semihosting with log https://docs.rs/cortex-m-log/0.6.1/cortex_m_log/log/index.html

For Itm you'll need registry block https://docs.rs/cortex-m/0.6.1/cortex_m/peripheral/struct.ITM.html
and then cortex_m_log::printer::itm::InterruptFree::new(cortex_m_log::destination::itm::Itm::new(<itm registers>))

[teburd]

This is only part of the example though, how do you take advantage of the Itm logging with say gdb and openocd attached? There's some other stuff that needs to happen right? I'm not that familiar with Itm, mostly familiar with RTT and UART style logging

[DoumanAsh]

It depends on how you configure gdb

E.g. https://github.com/DoumanAsh/2B/blob/master/scripts/.gdbinit is the script I was using to log semihosting output in opencd's stdout

For details for semihosting: https://docs.rs/cortex-m-semihosting/0.3.5/cortex_m_semihosting/
For ITM you need to run:
monitor tpiu config internal itm.fifo uart off 8000000 in gdb or in init script

OpenCD will log output into file itm.fifo
