-==== Upgrading OpenWRT ==== 
- 
-*WiP* 
- 
-If you have already installed OpenWrt and like to reflash for e.g. upgrading to a new OpenWrt version you can upgrade using the mtd command line tool. It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing. 
- 
-==== Serial for IMX-233-MAXI ==== 
- 
-You can use your usual serial levelshifter. Pinout is: 
- 
-<​code>​ 
-[UEXT] 
- 
- o o o o 
- 
-[USB/​ethernet] 
- 
-</​code>​ 
- 
-==== Further notes ==== 
- 
-The board uses a special boot image called bootstream / safeboot. The file includes a zImage, a compiled devicetree, and various preparation bootlets (power_, sdram_, linux_)- these are contained in package/​imx-bootlets. The image is created by the elftosb tool. 
- 
-A U-boot is being prepared by various people to replace the bootlets to enable easier debugging and further functions in the boot process.
