+# 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
+[...]
+```
+
+## U-Boot bootm command
+
+```
+bootm $1 $2 $3
+$1: Kernel image to load
+$2: RAM disk as rootfs
+$3: dtb - Flattened device tree blob
+```
