OK thanks for the link with the update details.
What that page does not tell is why the updated is needed, ie what is fixed with the new firmware.
What are the fault symptoms running older v.000 firmware?
I would also like to know the purpose of fitting the 10k resistor on the reset enable line, and the effects of fitting it
(mine does not have the resistor fitted). I have yet to check the firmware version, but my brand new Uno, received in the post yesterday appears to 'basically' work - I have downloaded a modified blink sketch which is working as expected, and now problems were encountered with downloading, etc
FYI I have the PTH Uno version, but I,m not sure how to check if its R1 or R2, there's nothing printed on it to say so ???
Thanks,
Texy
