Title: touchpad left button is now right button right button stopped working
Post by: ottosr on December 31, 2017, 07:40:22 PM
After me being so stupid to update, I had the touchpad problems as mentioned in the manual. I made a re-install with a fresh image, and made a copy to emmc. But now the left button became right and the right button doesn't work any more. When i try a mouse, all buttons work ok until I touch the touchpad, after that the left mouse button works fine, but the right one does nothing.
Where did it go wrong, and how do I get it to work as it should.
ps there is no differance in booting from sd or emmc

Did you read this topic: https://www.olimex.com/forum/index.php?topic=5954.0 ?

This seems to be a hardware problem, though not so hard to fix if you have a soldering iron.

I tried with resoldering the capacitors and buttons and update to latest keyboard firmware but issue is still. ..

did you test for the stray resistance on the button terminals?

I've tested that resistance on the buttons and it is good.

I think I fix it somehow. I've decided to replace the buttons and started with desoldering pump but it was hard to remove the buttons and I left it as it is. Then I decided to check after I've removed more of the tin on the connections and it worked fine.

Thanks for the reply, I just installed the firmware update. All seems to work again.
