Function Documentation

PmReturn_t plat_deinit

(

void

)

De-initializes the platform after the VM is done running.

PmReturn_t plat_getByte

(

uint8_t *

b

)

Receives one byte from the default connection, usually UART0 on a target device or stdio on the desktop

PmReturn_t plat_getMsTicks

(

uint32_t *

r_ticks

)

Gets the number of timer ticks that have passed since system start.

PmReturn_t plat_init

(

void

)

Initializes the platform as needed by the routines in the platform implementation file.

uint8_t plat_memGetByte	(	PmMemSpace_t	memspace,
		uint8_t const **	paddr
	)

Returns the byte at the given address in memspace.

Increments the address (just like getc and read(1)) to make image loading work (recursively).

PORT: fill in getByte for each memspace in the system; call sys_error for invalid memspaces.

Parameters:

	memspace	memory space/type
	paddr	ptr to address

Returns:

byte from memory. paddr - points to the next byte

PmReturn_t plat_putByte

(

uint8_t

b

)

Sends one byte out on the default connection, usually UART0 on a target device or stdio on the desktop

void plat_reportError

(

PmReturn_t

result

)

Reports an exception or other error that caused the thread to quit
