Function Documentation

otp_program()

int otp_program	(	const struct device *	dev,
		off_t	offset,
		const void *	data,
		size_t	len )

#include </__w/bridle/bridle/workspace/zephyr/include/zephyr/drivers/otp.h>

Program data to the given OTP memory.

Parameters

dev	OTP device
offset	Address offset to program data to.
data	Buffer with data to program.
len	Number of bytes to program.

Returns

0 on success, negative errno code on failure.

otp_read()

int otp_read	(	const struct device *	dev,
		off_t	offset,
		void *	data,
		size_t	len )

#include </__w/bridle/bridle/workspace/zephyr/include/zephyr/drivers/otp.h>

Read data from OTP memory.

Parameters

dev	OTP device
offset	Address offset to read from.
data	Buffer to store read data.
len	Number of bytes to read.

Returns

0 on success, negative errno code on failure.
