Thank you very much.

Hi @kelejichi ,

Thank you for your interest in Infineon's products and for the opportunity to serve you.
I think I need more information about the issue prior to sharing advice directly, so I hope you can clarify the following inquiries.
1) Has this function ever worked well?
2) What has changed recently？ （Software or Hardware）
3) What kind of types of the Trap happens?
4) Can you introduce the environment you test with? like hardware platform, demo code, etc.
Looking forward to your feedback.

BR,

Jeremy

Hi @kelejichi ，

Thanks for your reply.
In the ASCLIN_UART_1_KIT and ASCLIN_Shell_UART_1_KIT demos, they also call the Ifx_Fifo_write() function without triggering any traps. Maybe you can try.
Back to your issue, I'd highly recommend you follow the application note (AP32568) to locate the assembly instruction that triggered the trap, meanwhile, find out the difference in assembly instructions of this function between the ADS and BIFACES IDEs.

Hi @Jeremy_Zhou,

Thank you for your reply.

I run  the demo ASCLIN_Shell_UART_1_KIT  in local,  it's sure that they also call the Ifx_Fifo_write() function without triggering any traps.

I will check the difference in assembly instruction of this function.

one question: I can't find the  application note (AP32568) could you send it to me? this link can't find it.
