- Boots multi-user on ld(4) @ sdmmc(4) root and com(4) console.
- Ethernet (cpsw(4))
- SD/MMC controller (SD card and eMMC)
- EDMA3 (for sdhc(4))
- USB (host)
- CPU frequency scaling (various speeds between 300MHz and 1GHz)
- Random number generator trng(4)
What needs work
- eMMC 8-bit mode
- Framebuffer/graphics with LCD or DVI/HDMI capes
- Touchscreens on LCD capes
- USB (device)
- Growing the root file-system
- During the partitioning process, do not delete or format the first MSDOS (FAT) partition, as this is what your firmware by default boots from (unless you have prepared a boot partition on other media).
- For accident-free operation of resize_ffs, the filesystem it is supposed to grow needs to be either not mounted or at least not mounted for writing. To do that for a root filesystem, reboot to single user, 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 reboot
- When the system comes back up, the root file-system will have been expanded to fill the SD card.
