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

dev	smartDMA device
firmware	address of buffer containing smartDMA firmware
len	length of firmware buffer
