Re: [avr-gcc-list] uisp programming problem

[RogerB]

        Hi. I'm using uisp ver1.0b in the parallel mode and I
seem to be getting a strange error. If I burn a small file
(into a at90S2313) everything is ok but if it's larger than
150 or so bytes memory location 0 and 1 alway end up zero.
        I'm getting good signals to the chip, checked them
with a scope and they all looked good. The power supply is
regulated (5V)and the chips have bypass caps so there's
no noise.
        I added more delay but that didn't seem to do
anything. So here's what I've been doing
/opt/avrgcc/bin/uisp -dapa -v=3  --upload  whatever.hex
or I add the -dno-poll if that doesn't work
/opt/avrgcc/bin/uisp -dapa -v=3  --verify  whatever.hex
and I get back from the verify command
