[avr-chat] Slow communication with ATTiny13

[Robert von Knobloch]

Hello list,
I am developing a project using an AT Tiny 13 in a fairly
current-reduced application, which requires that I use the internal 128
kHz clock.
When programming (AVRDUDE + STK500 on OpenSUSE10.2), the write cycle is
OK, but verify causes a "avrdude: stk500_2_ReceiveMessage(): timeout"
error and after the code has eventually been read (takes some seconds) a
"avrdude: verification error, first mismatch at byte 0x00ca         0x64
!= 0x3f" where the location and target hex are seemingly random.
A manual inspection of the programmed code (AVRDUDE in terminal mode,
read flash [which works without timing out]) shows that the chip was
programmed correctly.
This behaviour also occurs with AVRStudio4 but can be resolved by
setting the fosc down to 1kHz. This does not work under AVRDUDE. Could
anyone point me to the place in the source files where I might be able
to tune the timeout??

Many thanks,

Robert von Knobloch
