tstellanova / itm_en.rs
Created March 13, 2020 21:30 — forked from richardeoin/itm_en.rs
Enable ITM output over the SWO pin for STM32H7 parts. The output is manchester coded and can be received by a debugger - eg. blackmagic probe
/// Enables ITM
///
/// If swo_enable is true, then the SWO output pin will be enabled
fn low_level_itm(dbgmcu: &stm32::DBGMCU, swo_enable: bool) {
// ARMv7-M DEMCR: Set TRCENA. Enables DWT and ITM units
unsafe { *(0xE000_EDFC as *mut u32) |= 1 << 24 };
// Ensure debug blocks are clocked before interacting with them
dbgmcu.cr.modify(|_, w| {

tstellanova / STM32H7_SWO_Output_Solution.py
Created February 7, 2020 00:27 — forked from mofosyne/STM32H7_SWO_Output_Solution.py
This generates codes that enables SWO output for STM32H7 and was tested on NUCLEO-H743ZI2. This is required because stm32h7 changed the registers that OpenOCD expects for SWO output.

Best to use 400Mhz, tried lower... but had issue with getting stable uart output
