Use FreeMASTER with i.MX8M-Plus

The platform support for FreeMASTER

https://www.nxp.com/design/design-center/software/development-software/freemaster-run-time-debugging...

doesn't mention the Cortex-M of i.MX8M-Plus.

Can FreeMASTER be used with it?

Hello,

unfortunately, we do not have any out-of-box example demonstrating the FreeMASTER use on i.MX8/9.

However, running the code adopted from any Cortex-M device such as MCXN947, i.MX-RT1060 or any Kinetis/LPC device shall be quite smooth. The only what needs to be done is to configure pins and UART clocks.

In case you use the MCUXpresso SDK for the CortexM development, it shall be even simpler as the initialization code will be very similar.

Regards,

Hi @MichalH 

I have a lot of applications running on M7 core of iMX8M-Plus.

Based on what I saw, printing on the UART is too slow to be non-intrusive (the baud rate of UAERT is too slow). At the moment, UART printing is the only way for me to debug, but with a lot of limitations.

FreeMASTER seems promising because I see in the picture that it supports JTAG/SWD.

But I learnt that using JTAG/SWD on M7 of iMX8MP is a little bit tricky.

Do you know if this works?
