MIN protocol not working properly on TI MCUs but works on STM about min HOT 2 OPEN

It sounds like you have a concurrency control problem: if interrupts get locked out for too long or tasks take to long to run then UART hardware buffers will lose bytes, and then of course frames will be dropped.

Have you tried a minimal system with no other interrupts and no locking out of interrupts? This might be hard if you have other software you don't have control over that locks out interrupts.

Hi kentindell thanks for the reply.
No, I haven't tried to run a minimal system yet, I will generate a new project with HalCoGen soon.
How can I be sure that I'm having concurrency control problems?

I toggled pins on the RM41L232 in the main loop every x and y millisecond and tested the pulse with an oscilloscope to check for timing issues, but no issues were found.

Moreover, I developed a C# app to echo MIN frames from the MCU and found that is just the RM41L232 MCU Rx side frames that were being lost.

something that is worth to mention is that with the STM I don't get back MIN_ID = 0xFF ACK frames, it just receives the packets and executes what's on the min_applicartion_handler()

Do you have a tip?
thanks
