MCU-PLUS-SDK-AM243X: TI_auto_init functions executed twice again during start up

Dear TI Community,

we have done further investigation regarding the related linked question.

We found out, that the init functions of the controller are executed again, after our own software is already in it's startup/init phase.

This causes the ISR callbacks to be reseted to default values (0x00000000) instead of the actual ISR callbacks. 
Because of this we see the behavior described in the related thread (https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1159558/am2434-am2434b-enet_lwip_icssg-stucks-in-hwip_irq_handler_c?tisearch=e2e-sitesearch&keymatch=HwiP_irq_handler_c#). 

Do you have any Idea what could cause this behavior?
Is it possible that some kind of reset is occurring during our init phase where we initialize e.g. the ETH Phys and the LWIP stack.

If my questions is not clear, please tell me what information to provide Slight smile

Thanks in advance, Best Regards
Robin
