have a compatible AVR emulator to check things out in detail. I am
thinking that there is some fuse setting that divides the input clock
by 8??? but that is just a fantasy.
Update: No, something else is wrong; the Teensy AT90USB behaves in
exactly the same way.
Status: Open
Priority: Low. Setting the terminal BAUD to 4800 solves the issues. However,
I suspect that this means that there are other lurking timing issues
@@ -900,13 +902,16 @@ o AVR (arch/avr)
Priority: The priority might as well be low since there is nothing I can do about
it anyway.
Description: There is a OS test configuratin for the Micropendous AT90USB at
configs/micropendous3. However, as currently configured it will not
fit into the AT90USB memory. Some tuning and scaling is required and
obviously this configuration is untested.
Description: Many printf-intensive examples (such as the OS test) cannot be executed
on most AVR platforms. The reason is because these tests/examples
generate a lot of string data. The build system currently places all
string data in RAM and the string data can easily overflow the tiny
SRAMs on these parts. A solution would be to put the string data
into the more abundant FLASH memory, but this would require modification
to the printf logic to access the strings from program memory.
Status: Open
Priority: Low for me because the AT90USB647 is not a very interesting target to
me because of its limited memory capability./
Priority: Low. The AVR is probably not the architecuture that you want to use
for extensive string operations.
