Hello,
Sometime my projet works and sometime not. After a low search, I'm facing with a strange behavior, and I don't know how it can happen.
Look at my screenshop, after two simple instructions :
Code:
mov r0, lo(0x78)
orh r0, hi(0x78)
My register r0 value is 0x00010078 and not 0x00000078. It doesn't happen all times, but when it happen, my program crash due to a overflow later.
How it can be possible ?
Thanks for your help,
Pascal |

| Wrong forum. This is an AVR32 question, not an AVR Studio 5 question. |

Moved here. Perhaps I should have deleted it as there is the same thread here now.  |

Hi Pascal,
with Atmel AVR Studio 5 (Version: 5.1.148) the debugger works fine:
Code:
mov r0,lo(0x78)
orh r0,hi(0x78)
R0 0x00000078
or just
Code:
mov r1,0x78
R1 0x00000078 |

Thanks for your reply,
Now I fixed my issue by configuring wait state to access flash, which is mandatory when we use more than 33 Mhz. I forgot to select it before, and my MCU was unstable. Now all works fine,

Thanks again,
