# ODroid C1
## New kernel
With the old kernel (3.10, linux-odroid-c1 package) you need to set in `/boot/boot.ini`:

```
$ cat /boot/boot.ini
[...]
setenv condev "console=tty0 console=ttyS0,115200n8"
[...]
ext4load mmc 0:1 0x21000000 /boot/uImage
ext4load mmc 0:1 0x21800000 /boot/dtbs/meson8b_odroidc.dtb
fdt addr 21800000
[...]
```

Those settings are not working for the new kernel (5.5.8, linux-armv7-odroidc1 package).
You need to copy `meson8b-odroidc1.dtb` and set the following:

```
$ cp /boot/dtbs/meson8b-odroidc1.dtb /boot/meson8b-odroidc1.dtb
$ cat /boot/boot.ini
[...]
setenv condev "console=tty0 console=ttyAML0,115200n8"
[...]
ext4load mmc 0:1 0x21000000 /boot/uImage
ext4load mmc 0:1 0x21800000 /boot/meson8b-odroidc1.dtb
fdt addr 21800000
[...]
```
