Hello all,
i have a problem.
First about my Application: I have written a bootloader, it works with programmin and bootjump all right. But I want to use a bootflag.
I have define the RAM1 for the Bootloader and the Application in 0x1000000 with size 0x4000 then i have define RAM2 for the bootFlag with 0x1000500, size 0x1F (see in appendix RAM Config.png).
Then my code starts like this:
#inlcude...
static bool __attribute((at(0x1005000))) bootFlags;
int main(void)
{
...
bootFlags=1;
...
}
At the programm counter point ,,bootFlags=1; ,, i get an hard fault.
If i would change the code like this:
static bool __attribute((at(0x1003000))) bootFlags;
int main(void)
{
...
bootFlags=1;
...
}
The Adress is in the ROM1 and it works.
But i want this bootFlag in a seperately ROM2.
Please help me.
Best Regards
DDMW
