This is probably a configuration problem. There is no device created for the spidev and spi devices are supposed to be configured in script.bin so there is a lot of room for weird errors. So I think it's better to figure out how to configure spi in mainline than it is to resurrect it on 3.4. > >> >> So I upgraded to linux 4.0rc4 and tried to convince it to boot on the >> a10s olinuxino. >> >> Problems >> >> 1) no serial input (possibly wiring issue - need to investigate) >> >> 2) no USB HID input >> >> 3) display does not work properly in u-boot - no signal on one DVI >> screen, red console background on another DVI screen > > These look like u-boot problems.

I had it as m which does not work that well even if the module is loaded. Also the HID keyboard works with the console then and re-testing u-boot I can stop it with the keyboard too. Maybe I just was not fast enough. Thanks Michal -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
