Hi all,
first of all: thanks for this wonderful work!
I am just trying to get an UNO R3 together with a W5100 shield to work.
However, in case of power loss (or first power up) the sketch does not properly load, but as soon as I press reset, everything works fine.
As far as I could find out the arduino boots so fast, that the shield cannot properly initialize.
So I tried to add a delay to optiboot for my special purpose - all I could achieve was that I could not burn a program any more, as avrdude ran into timeouts.
So my question: can anyone please tell me, WHERE exactly in the optiboot.c code a delay could be placed without interfering with the flashing routines?
/edit: the TIMEOUT_MS could point in that direction, but seems not to be supported (yet)?
Thanks in advance!
Otto
