   # What needs work
   
    - USB (host); isochronous transfers.
    - WiFi

  - Growing the root file-system (**not required with NetBSD -current after 2015-04-07, or by NetBSD 7 after 2015-08-06**)  ## Installation with sshramdisk image
    - During the partitioning process, do not delete or format the  
      first MSDOS (FAT) partition, as the Raspberry pi firmware is  
      hard coded to boot on the SDCAD / 1st MSDOS partition / Firmware  
      updates and boot loader.  
    - Copy /boot/cmdline.txt to /boot/cmdline.txt.orig  
    - Edit /boot/cmdline.txt and add the '-s' flag to the end of the first line of text to boot into single-user mode.  
    - For the next steps, the root filesystem mustn't be mounted rw. So reboot, and at the prompt to enter the pathname of shell,  
      press return for the default (/bin/sh).  
    - At the # prompt, type  
   
         "disklabel -i ld0" and press return.  
   
    - At the partition> prompt type "A" and press return.  
   
            Adjust disklabel sector from 4194304 to 62333952 [n]?  
            Type "y" and press return.  
   
    - partition> prompt type "a" and press return.  
   
            Filesystem type prompt, press return to use the current value (4.2BSD).  
            Start offset prompt, press return to use the current value.  
            Partition size prompt, type "$" and press return to grow the  
            partition to use all available free space.  
   
    - partition> prompt type "W" to save the changes to the disklabel.  
   
            Confirm this choice by typing "y" at the Label disk prompt.  
            Type "Q" and press return to quit disklabel.  
   
    - At the # prompt (shell), type  
   
            fsck -fy /dev/rld0a  
            resize_ffs -y /dev/rld0a  
   
    - This may take a few minutes, be patient!  
   
            fsck -fy /dev/rld0a  
            mount_msdos /dev/ld0e /boot  
            mv /boot/cmdline.txt.orig /boot/cmdline.txt  
            reboot  
   
     - When the system comes back up, the root file-system will have been expanded to  
            fill the SD card.

 # Updating the firmware  ## Updating the kernel
   
 You probably don't want to do this. Firmware updates can break things,  
 and the latest firmware that's been tested is already included in the  
 NetBSD build you installed.  
   
 If you're feeling adventurous (or are the port maintainer), here's what  
 to test whenever you try new firmware:  
   
 - Audio  
 - OMXPlayer (and [[!template id=man name="vchiq"]])  
 - Serial/framebuffer console  
 - CPU frequency scaling  
   
 That goes for all of `rpi[0123]`.  
   
 Upstream firmware releases are  
 [on GitHub](https://github.com/raspberrypi/firmware/releases).  
 Copy all files except `kernel*.img` into `/boot` and reboot.
