Cubox-i 4 pro
Installed Fedora kernel 4.0.0-0.rc3.git1.1.fc23.armv7hl eth0 available
but no connection.
As per http://rglinuxtech.com/?p=1338 modified
linux/arch/arm/mach-imx/mach-imx6q.c on line 214
Making the modification suggested (in the above article) and
recompiling the kernel eth0 successfully connects.
U-boot SPL and image are from u-boot-imx6 git.
To use the normal Fedora method of kernel selection I have modified
a-b-c.d configuration files /etc/a-b-c.d/19-config-adds
added a new line at the end of the section headed
#Freescale i.MX such as Wandboard and Utilite
c_add cubox-i 'run config_default; u_extraargs="\$u_extraargs
console=\$console,115200n8 console=tty1 video=1920x1200@60";
u_k_addr=0x10800000; u_ramfs_addr=0x12800000; u_dtb_addr=0x18000000;
skip_dtb=""; pass_dtb=1; u_dtb=imx6q-cubox-i.dtb; u_iodevs="mmc usb";
u_fs=ext2; u_boot=bootz; u_devpart="0:1 0:2 0:3 1:1 1:2"'
modified a-b-c.d configuration files /etc/a-b-c.d/21-autodetect
Added another test for the Cubox-i with the board name mx6-cubox-i (
the line number 24 for elif test -n \$board; then)
elif test -n \$board; then
if test \$board = cubox-i; then
run config_cubox
fi
if test \$board = mx6-cubox-i; then
run config_cubox-i
fi
Modified boot.cmd to include cubox-i
added ca13 then renumbered all beneath ca19 (ca20)
setenv config_cubox 'echo Configuring for cubox;run config_imx;
setenv u_dtb \$fdt_file'
ca12=config_cubox
setenv c12 "run config_cubox; run showdefs"
setenv config_cubox-i 'echo Configuring for cubox-i;run
config_default; u_extraargs="\$u_extraargs console=\$console,115200n8
console=tty1 video=1920x1200@60"; u_k_addr=0x10800000;
u_ramfs_addr=0x12800000; u_dtb_addr=0x18000000; skip_dtb=""; pass_dtb=1;
u_dtb=imx6q-cubox-i.dtb; u_iodevs="mmc usb"; u_fs=ext2; u_boot=bootz;
u_devpart="0:1 0:2 0:3 1:1 1:2"'
ca13=config_cubox-i
setenv c13 "run config_cubox-i; run showdefs"
setenv config_tegra 'echo Configuring for tegra;run config_default;
u_extraargs="\$u_extraargs console=ttyS0,115200n8"; u_k_addr=4080000;
u_ramfs_addr=4800000; u_dtb_addr=4000000; skip_dtb=""; pass_dtb=1;
u_iodevs="usb mmc"; u_fs=ext2; u_boot=bootz; setenv fdt_high 0x2C000000;
setenv initrd_high 0x2C000000; u_devpart="0:1 0:2 1:1 1:2";
u_dtb=\${soc}-\${board}.dtb'
ca14=config_tegra
setenv c14 "run config_tegra; run showdefs"
setenv config_am33xx 'echo Configuring for am33xx;run config_default;
u_k_addr=0x80300000; u_ramfs_addr=0x82000000; u_dtb_addr=0x81400000;
skip_dtb=""; pass_dtb=1; u_iodevs="mmc usb"; u_fs="ext4 ext2 fat";
u_boot=bootz; u_devpart="0:3 0:2 0:1"; u_extraargs="\$u_extraargs
console=ttyO0,115200n8"; u_dir="/boot/ /"; setenv bootm_size 0x10000000;
run findfdt; u_dtb="\$fdtfile"'
Also included the changes made in /etc/a-b-c.d/21-autodetect
elif test -n $board; then
if test $board = cubox-i; then
run config_cubox
fi
if test $board = mx6-cubox-i; then
run config_cubox-i
fi
Increased the c_count from 19 to 20
c_count="1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20"
The only problem I have noticed is the kernel list from extlinux.conf
does not appear, but at least the system boots and after a kernel update
the new kernel is selected for boot.
