[eusebiudapatech]

Hello,

I am getting a BusFault at the following generated line:

eusebiudapatech_0-1744479144916.png

The function is called in StartOs() function and it write the STM0 control register.

The code is generated from Tresos using the RTOS and RTD plugins.

I have checked the address and it's the correct STM0 control register address.

Hi @eusebiudapatech,

Is the STM0 clock enabled?

MC_ME PRTN1_COFB0_STAT[29]

Thanks

Thank you for the hint. I didn't call the Mcu_SetMode API to switch to RUN mode where STM0 is enabled. That solved the problem.
