RT1020/1050 DMA memory to peripheral

I am looking for some example of source code for RT1020 or RT1050, with DMA, Memory to Peripheral, or Peripheral to Memory, using several GPIO ports.


In the SDK there are examples using DMA for Memory to Memory, Memory to Serial Port (SPI, UART, I2C...),  and Serial Port to Memory, but I need to Read or Write several GPIO ports by DMA.

Can anyone provide an example of source code Memory to Peripheral or Peripheral to Memory with several GPIO ports, or is there a User Manual about it?

Best regards.
