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
