ok been trying...
first how i put a variab;le in user flash?
lets say
flash[3]{
1,2,3
}
now with flashc.h i can call to write 1 byte
extern volatile void *flashc_memset8(volatile void *dst, U8 src, size_t nbytes, Bool erase);
i want to write 0xFF to flash[0]
been trying not working
I think all the flash functions are used with the USB bootloader source code, take a look in the framework SERVICES/USB/CLASS/DFU
-sma
ok good deal
Main thing I still am having troubles with unlike avr 8 bit is how do i define data in flash at the location I want, and also how to I view my flash. I figured out how to view the ram, but no flash..
thanks
How to view it in AVR32Studio??
yes
or anywhere else
like i could with avrstudios 4
i could see the flash
also if i am setting a array in flash to be wrote to during runtime (meaning in user flash)
how to I declare it?
volatile unsigned char test[] or
static or ??
thanks for the replies
volatile unsigned char test[3] =
{
0x00,0x00,0x00
};
// param dst Pointer to flash destination.
// param src Source half-word.
// param nbytes Number of bytes to set.
// param erase Whether to erase before writing: \c TRUE or \c FALSE.
// return The value of \a dst. */
flashc_memset8(&test[1], 0xFF,1,TRUE);
This compiles with no warnings or errors. But is my array in flash?
try to use const unsigned char
-sma
I did, and get this warning...
Severity and Description Path Resource Location Creation Time Id
warning: passing argument 1 of 'flashc_memset8' discards qualifiers from pointer target type training_lab1 training_lab1.c line 90 1200950986827 28502
set as in the post above, i get no warnings.
I will try both ways tonight.
Still wanna know how to see my flash contents.

Did you try the debug session in AVR32Studio then memory view, check the flash address 0x80000000?
-sma
yes and all I got was ?? ?? in the data area, so I am thinking that the view memory is just for sram......
I can see my ram variables there, but not the flash....
you can try the command line
avr32program read -o0x8000000 -s512
to read 512 bytes.
ok, will give that a try
I assume that is from a dos shell?
Mike
yes it is and is not flash at 0x80000000 and not 0x8000000?
0x8000 0000
ok declare it as const in test[3] ={0,0,0}
and than call it... will write flash on runtime.
Problem Solved
