Function Documentation

◆ dma_smartdma_install_fw()

void dma_smartdma_install_fw ( const struct device * dev,
uint8_t * firmware,
uint32_t len )

install SMARTDMA firmware

Install a custom firmware for the smartDMA. This function allows the user to install a custom firmware into the smartDMA, which implements different API functions than the standard MCUX SDK firmware.

Parameters
devsmartDMA device
firmwareaddress of buffer containing smartDMA firmware
lenlength of firmware buffer
