AVR Freaks

Have you found the cause for the problem yet?

I have similar problems with JTAGICE MkII, but on a Win 2k system.
I used AVR Studio 4.12 and mostly everything was ok, but in the debugger it ignored the memory locations I defined in my project (WinAVR). The HEX output is ok, so there is no big problem. When I installed 4.13 it showed the memory correctly, but the JTAGICE stopped working.

Now I removed 4.13 and installed 4.12 again.
Who else has similar problems,or better - a solution?

I am using a Tiny13 and wanted to store some Information (Software version defined in the software, serial number generated by the device programmer, and so on).
I defined a memory segment beginning at 0x3f0 (the last 16 Bytes in the program memory)
This is done in the memory settings by:
LDFLAGS += -Wl,-section-start=.Ser_Num=0x3f0

In the software:
const unsigned char Data[16] __attribute__ ((section (".Ser_Num"))) = "123456789 112233";

In the Hex-output the version number appears as it should, but in the debugger I dont see it in the memory window (all Bytes FF). But when I read these bytes in my programm the information is there.

This was the reason for installing 4.13, because this was solved (at least in the simulator, because debugging is not possible).

At the moment im using 4.12 again and manage to live with the problem that the information is not displayed correctly.

Hope this helps to understand the problem.
But still, with 4.13 the JTAGICE is not working?
