Writing data from UART with DMA in a new Array

[12914A]

Hi all,

I receive the data, but the problem is, that the CITER value from the ELINKNO register doesn't match with the value I got, when I write the registervalue in a variable.
Additionally the data in the recv_buf is not written from zero or the same field than in Msg.
I attached the DMA init and the code for the UART IRQ handler.

Please help me.

Hi @12914A,

Have you read the register's value by debugging?

You can also test the example included with the example projects, which is based on the code in AN5413: S32K1xx Series Cookbook.

Best regards,
