Hi all, I have got the board Chipsee BeagleBoard-XM Expansion V2.
It mounts ads7846 touchscreen. In dmesg I have:
ads7846 spi3.0: no device detected, test read results was 0x00000000 ... regulator_init_complete: vads7846: incomplete constraints, leaving on
and the touchscreen doesn't work. Any suggestions?
Thanks Francesco
Any help?

I don't think your touch screen got detected here. Do you capture any touch events if you run "getevent" on Android console?
and the touchscreen doesn't work. Any suggestions?
Thanks Francesco

Please change the mux setting of the SPI-3 pins. Otherwise, SPI3 will not work. You need to set SPI-3 Clock as input. Refer: elinux.org/BeagleBoard/SPI
