Error DMA SPI

Hi, 

So I have a driver for the spi that is similar to the driver offer by the nxp and it works perfectly using interrupts to send and receive data, right now I'm having this issue when i try to use the dma do handle the writing and copying of the data from the spi registers. I realized that after i set the RSER bits to generate the spi request in tx and rx (the same way as done in the nxp drivers) as soon as i write the RSER register an error is raised to the tx channel the tx Source address and some configurations are also changed and I have no clue on what it is raising the error.

 

 

Kind regards, 

Ailton Lopes
