Part Number: TDA2SX

Hi team,

Using the TDA2XX processor, hang uart3 on A15 (MPU0) using official routine tests. The test is as follows:

1) Data can be received and sent normally using polling.

2) Based on the first point, when a customer reference routine configures the serial port into interrupt mode, the serial port interrupt cannot respond and no data can be received. The interrupt configuration is as follows: 

Reference routine: 

And made the following modifications:

Could you help check is there anything need to taken care of? Thanks.

Best Regards,

Cherry

    Hi,

    The customer found that the uart3 code was properly interrupted on IPU0, but not on A15 during test. What is the interrupt initialization flow for URAT3 on A15? Or could you help share the other peripheral interrupt initialization flow for A15? 

    Thanks and regards,
