Hi All,

I am having troubles reading Sig. Byte on Tiny13 Date Code:0432D. I am using Studio 4.09 and stk500 firmware 1.46. I have looked over the forum for information about the Tiny13 and any problems that others have had.

I get the "Failed to ..." message when trying to read the sig. byte.

I have used both the sckt3400d1 socket and wired directly to a isp header. Both do not work. After setting the stk500 clock to 32khz I still have not sig. byte. So at this point I got out the DSO and started looking at the SCK, MOSI, MISO signals! I see that there is an extra SCK clock high in the set of sck clock's to the AVR. Has any one else seen this in the stk500 low voltage serial programming?

Thanks for any help!

I will be getting the latest version of Studio 4.10 and testing the new firmware.

[edit]

I have been able to use this same firmware to program mega8's, mega162, mega48's, etc.
Cheers,
Caleb Austin
