Hi, I've bought a Chestnut43 board and could not get the touchscreen working: Following Kernel Message: [ 291.757324] ads7846 spi1.0: touchscreen, irq 274 [ 291.757598] ads7846 spi1.0: no device detected, test read result was 0x000000 I've looked at the Board and could not find any ADS7846 on it. You can see a free Pad in the Picture which is attached. I am right that Gumstix has forgotten to solder the Chip? Or can it be anywhere else? I've mailed Gumstix about my Problem and they say: "Each Chestnut43 board has been tested for touch screen function prior to shipment. Please use the Gumstix mailing list for technical support. " I want to be sure that this is really an Hardware issue, before I send it to Gumstix for RMA. Regards Jörn |

Hmm, well I can confirm that my chestnut43 has the ADS7846 IC in that location.

Gumstix has a long history of extremely poor quality control on hardware. Issues like this one are why I won't spend hundreds of dollars on the parts. I'll stick to the Beagleboard, because they tend to get their stuff done really well. That, and the poor support you are getting from Gumstix itself. It's not very nice of them to respond the way they have to your inquiry.
