Hi All,
I am currently working on Tinyos platform. I running code on TOSSIM - tinyos
simulator. This code is contained in HPLAt45dbIOP.nc file. My code basically
wants to write data to flash memory for micaz sensors. But in TOSSIM it is
unable to recognise the instructions of the avr assembler. I have attached only
the part of code which is giving error. Please guide as I am stuck with this
for a long time and my submission deadline is very near.
#define BITINIT \
uint8_t clrClkAndData = PORTD & ~0x28
#define BIT(n) \
PORTD = clrClkAndData; \
asm __volatile__ \
( "sbrc %2," #n "\n" \
"\tsbi 18,3\n" \
"\tsbi 18,5\n" \
"\tsbic 16,2\n" \
"\tori %0,1<<" #n "\n" \
: "=d" (spiIn) : "0" (spiIn), "r" (spiOut))
async command uint8_t FlashSpi.write(uint8_t spiOut) {
uint8_t spiIn = 0;
// This atomic ensures integrity at the hardware level...
atomic
{
BITINIT;
BIT(7);
BIT(6);
BIT(5);
BIT(4);
BIT(3);
BIT(2);
BIT(1);
BIT(0);
}
return spiIn;

Sounds like your compiler is calling the host's assembler, rather than
the AVR specific one.
I remember tinyOS uses a fairly tweaked build environment, so you
probably have to ask in a group specific to tinyOS about that.
Can anybody please look into this and let me know what is missing in my program
so that these instructions are recognised.

Vandna Bhasin
