Re: [Gumstix-users] Touchscreen problem on palo43

[Trilogic <ro...@ex...>]

The test seems to be invalid, on my semi-working Chestnut43 the in0_input
value changes similar to the Palo43 board, but the in1_input remains at 0
just like the Palo43 board even though the touch works fine on the
Chestnut43 board.

The Chestnut43 board does have it's own unique problems and will be going
back to GS for RMA also. At initial power up all works fine, but any type of
reboot/reset without removing power renders the LCD inop. The LCD will NOT
display again until all power is removed from the Chestnut43 include the USB
console connection. After a few minutes sans power, reapply power and all is
well until next reboot/reset. Really can't give either of these two boards a
very good review.

I am waiting on my 3.5 inch LG display so I can begin testing the Palo35
board. I hope it proves to be 100 percent functional..
