Function Documentation

pi_dma_read_data()

void pi_dma_read_data	(	void *	src,
		void *	dst,
		size_t	length )

Perform a DMA read operation from the PI (Peripheral Interface).

Parameters

src	Source address.
dst	Destination address.
length	Length of data to read.

pi_dma_write_data()

void pi_dma_write_data	(	void *	src,
		void *	dst,
		size_t	length )

Perform a DMA write operation to the PI (Peripheral Interface).

Parameters

src	Source address.
dst	Destination address.
length	Length of data to write.

fatfs_fix_file_size()

void fatfs_fix_file_size

(

FIL *

fil

)

Align the file size to the SD sector size to prevent partial sector load.

Fix the file size in the FAT filesystem.

Parameters

fil	Pointer to the file object.

fatfs_get_file_sectors()

bool fatfs_get_file_sectors	(	char *	path,
		uint32_t *	address,
		address_type_t	type,
		uint32_t	max_sectors )

Get the file sectors in the FAT filesystem.

Parameters

path	Path to the file.
address	Pointer to store the address of the file sectors.
type	The type of address (memory or PI).
max_sectors	Maximum number of sectors.

Returns

true if an error occurred, false otherwise.
