Function Documentation

dump_hex()

void dump_hex	(	uint32_t	start_addr,
		uint32_t	count
	)

Dumps memory content in hexadecimal format.

This function dumps the content of memory starting from the specified address in hexadecimal format. It prints the hexadecimal values of memory contents and ASCII characters corresponding to printable characters.

Parameters

start_addr	The starting address of the memory region to dump.
count	The number of bytes to dump.

printf()

int printf	(	const char *	fmt,
			...
	)

Print message via UART.

This function is used to print formatted message to the terminal via UART serial port.

Parameters

fmt	Format string describing the format of the message to print.
...	Variable argument list used to fill placeholders in the format string.

Note

This function is typically used in embedded systems for debugging and outputting system status information.

printf_dram()

int printf_dram	(	const char *	fmt,
			...
	)

printk()

void printk	(	int	level,
		const char *	fmt,
			...
	)

Print message to kernel log.

This function is used to print the message with specified level to the kernel log.

Parameters

level	Information level, typically used to specify the importance or type of the message.
fmt	Format string describing the format of the message to print.
...	Variable argument list used to fill placeholders in the format string.

Note

This function should be used within the kernel to record important system information or debug messages.

uart_printf()

void uart_printf	(	const char *	fmt,
			...
	)

Print message via UART.

This function is used to print formatted message to the terminal via UART serial port.

Parameters

fmt	Format string describing the format of the message to print.
...	Variable argument list used to fill placeholders in the format string.

Note

This function is typically used in embedded systems for debugging and outputting system status information.
