 [ODROID-C1](http://www.hardkernel.com/main/products/prdt_info.php?g_code=G141578608433&tab_idx=1) was a $35 quad-core SBC from Hardkernel. ODROID-C1 support was introduced in NetBSD 7.0.  It has been succeeded by the [ODROID-C1+](http://www.hardkernel.com/main/products/prdt_info.php?g_code=G143703355573), which is supported by the same NetBSD kernel.  [ODROID-C1](https://www.hardkernel.com/shop/odroid-c1-2/) was a $35 quad-core SBC from Hardkernel.

   # U-Boot Environment
   
   To read/write U-Boot environment variables from NetBSD, download and compile the following program: <http://ftp.netbsd.org/pub/NetBSD/misc/jmcneill/odroidc1/uenv.c>
   
   # Automatically booting a backup kernel
   
   *These instructions assume the kernels live on eMMC. Adjust devices accordingly for SD card setup.*
   
   To setup an ODROID-C1 to fall back to a recovery kernel in the event of a boot failure, install the recovery kernel as /boot/onetbsd.ub.
   
   Create /boot/boot.ini as follows:
   [[!template  id=programlisting text="""
   ODROIDC-UBOOT-CONFIG
   setenv bootargs "root=ld0f awge0.mac-address=${ethaddr}"
   fatload mmc 0:1 0x22000000 boot.scr
   source 0x22000000
   """]]
   
   Create /boot/boot.txt:
   [[!template  id=programlisting text="""
   # regenerate with:
   #  mkubootimage -A arm -C none -O netbsd -T script -a 0 -n "NetBSD/odroidc1 boot" boot.txt boot.scr
   
   setenv rescue_kernel "onetbsd.ub"
