TELOSb External Flash
[Device Drivers]

Defines
#define	TELOSB_RAMFUNC   __attribute__((section (".data")))
	this attribute causes the function to be mirrored in RAM, allowing the function to be called even if the program flash has been erased.
#define	dev_open_DEV_TELOS_FLASH(void)   mos_mutex_lock(&telos_flash_mutex)
	gain an exclusive lock on the External Flash. Any other threads calling dev_open_DEV_TELOS_FLASH() will block until the owner calls dev_close_DEV_TELOS_FLASH().
#define	dev_close_DEV_TELOS_FLASH(void)   mos_mutex_unlock(&telos_flash_mutex)
	release exclusive lock on the External Flash. Any other thread blocking on dev_open_DEV_TELOS_FLASH() will now unblock.
Functions
uint8_t TELOSB_RAMFUNC	dev_read_DEV_TELOS_FLASH (void *buf, uint16_t count)
	Read count number of bytes from the flash and store it in buf. Note: This function is mirrored in RAM and can be called even after the program flash has been erased.
uint8_t	dev_write_DEV_TELOS_FLASH (const void *buf, uint16_t count)
	Write count bytes from buf to the external flash.
uint8_t	dev_mode_DEV_TELOS_FLASH (uint8_t md)
	turn the flash on or off. Accepted parameters are: DEV_MODE_OFF: Turn the device off. DEV_MODE_ON: Turn the device on.
uint8_t TELOSB_RAMFUNC	dev_ioctl_DEV_TELOS_FLASH (int8_t request,...)
	send an IO Control command to the flash driver. Accepted parameters are: DEV_SEEK, [uint32_t address] TELOS_FLASH_BULK_ERASE TELOS_FLASH_SECT_ERASE, [uint32_t address] Note: This function is mirrored in RAM and can be called even after the program flash has been erased.
