[Question] How do I do to secure LCD on L4 Linux ?
Hi, l4hackers I'm try to securing LCD on L4 Linux using Freescale i.MX6Q SABRESD board. I succeeded in securing Ethernet on L4 Linux. But I don't yet secure LCD on L4 Linux. LCD(HSD100PXN1) is connected by LVDS. I've modified as below.. 1.' .io' I've added LDB control register address to '.io' file. 2. 'mach_setup.c' (l4linux/arch/l4/kernel/arch-arm/mach_setup.c) I've added code for LVDS. Qusetion 1. Did I do wrong modification ? Qusetion 2. Must I do something outside of that ? How do I do to secure LCD on L4 Linux ? If you give a bit hints me, I would appreciate it .

Looks good but probably just a start.
Qusetion 2. Must I do something outside of that ?
At least you also need to enable the driver but I guess you did that? So assuming the driver is trying to start up, where is it bailing out before successfully completing? Adam -- Adam adam@os.inf.tu-dresden.de Lackorzynski http://os.inf.tu-dresden.de/~adam/
