Function Documentation

system_boot_app()

void system_boot_app

(

void

)

Boot application program.

system_exe_load()

int system_exe_load	(	int(*	dev_init )(void),
		int(*	stream_get )(uint32_t *rdata) )

Load executable: get data from device stream and store to main memory.

Parameters

dev_init	Function pointer ("int foo(void)") for device setup.
stream_get	Function pointer ("int bar(uint32_t* rdata)") to get the next consecutive 32-bit word from an application source stream.

Returns

0 if success, non-zero 0 if error.

system_exe_store()

int system_exe_store	(	int(*	dev_init )(void),
		int(*	dev_erase )(void),
		int(*	stream_put )(uint32_t wdata) )

Store executable: copy data from main memory to device stream.

Parameters

dev_init	Function pointer ("int foo(void)") for device setup.
dev_erase	Function pointer ("int tmp(void)") for device erasure.
stream_put	Function pointer ("int bar(uint32_t wdata)") to put the next consecutive 32-bit word to an application source stream.

Returns

0 if success, non-zero 0 if error.

system_setup()

void system_setup

(

void
