Touchscreen

[Wajidali Whowe]

Hi Matthias, 
now the lua script is like this and I just added one additional linux to see whether it is working, however, still I have no usb support:

hid = l:new_channel(); 

local linux_caps = {
  vbus = io_caps.linux_bus,
  rtc = rtc_caps.rtc,
  ev = hid:svr(),
  rom = L4.Env.rom,
};


l:start(
        {
                caps = linux_caps,
log      = { "server", "g" },
        },
        "rom/vmlinuz.android mem=256M l4-input-srv.enable=1 console=ttyLv0 ramdisk=rom/openwrt-x86-alix2-rootfs.tar.gz root=1:0 ramdisk_size=32768 l4x_rd=rom/openwrt-x86-alix2-rootfs.tar.gz init=/etc/preinit");



local mag_caps = {
mag = l:new_channel(),
svc = l:new_channel(),
};


l:start({
          caps = {
    vbus = io_caps.con_bus,
    fb   = fb_caps.fb,
    ev   = hid, 
    mag  = mag_caps.mag:svr(),
    svc  = mag_caps.svc:svr(),
  },
          log      = { "mag", "g" },
  l4re_dbg = L4.Dbg.Warn,
        },
"rom/mag");


local linux_caps2 = {
  rtc = rtc_caps.rtc;
  rom = L4.Env.rom;
  fb = mag_caps.svc:create(L4.Proto.Goos, "g=470x640,pos=10,20");
};


l:start(
        {
                caps = linux_caps2,
                log = {"simpleLinux" , "g"}, 
        },
        "rom/vmlinuz.android mem=256M  console=ttyLvx ramdisk=rom/openwrt-x86-alix2-rootfs.tar.gz root=1:0 ramdisk_size=32768 l4x_rd=rom/openwrt-x86-alix2-rootfs.tar.gz init=/etc/preinit");


Best Regards,

You need to start L4Linux before mag. mag is waiting for the server to connect
to its ev cap.
