I was able to run the HSM demo project HSM_Demo_TC37A (with Gnu Config for TC and ARM) on the Lite Kit board, and generated a bridge interrupt from HSM to Host, encrypt and decrypt.
But when I add on the Aurix side a simple GPT12 interrupt (as per aurix code example GPT12_Timer_Interrupt_1_KIT_TC375_LK) it doesn't work, the GPT12 interrupt never fires.
If I comment out IFX_USE_SW_MANAGED_INT, the GPT12 works but the HSM bridge IRQ doesn't.

How can I keep both working ? Can the HSM interrupts work without IFX_USE_SW_MANAGED_INT ?
