2006-03-23:
Thanks to Serge Nikolaenko CF is working. Also bluetooth is working.
2006-01-26:
cpufreq is working (along with the voltage changes). It supports frequences from 104MHz to 624MHz.
2006-01-20:
Added full USB Client support (networking over USB)
2005-12-30:
I made some changes to the buttons driver and now Opie recognizes them all except for the Tasks button. I think this is only a small bug and will be fixed soon. I added a "Known Issues and Bugs" section in the wiki below to have a small overview of the major showstoppers for a enduser-ready release. I also try to document all changes I had to make to files included in Familiar. This might come in handy later.

Look here for the generic steps: MyPal730setupChanges to 0.8.4 Familiar Image
-
NO real changes - just update your /dev/ and fstab
Kernel compilation
Kernel options
The HaRET startup.txt should contain the correct kernel parameters - special notes on these options:
-
mem=64m: Use all of the 64MB ram in a730
-
mem=128m: Use all of the 128MB ram in a730w
USB Networking
Just ensure "usbnet" module is compiled/loaded on Host PC. Plug in USB cable whenever you need it.
To use NFS-root - connect it before Linux start.
See UsbNet for for information.
USB host
With USB-HID and USB-storage kernel options enabled we have a USB hub. It allows to run all this at once over an external USB hub:
-
keyboard
-
mouse
-
a USB flash drive 512Mb
-
card reader on 4 cards
-
..... USB HDD 120Gb !
802.11b Wireless
The A730 comes in two models, the plain A730 and the A730W. The difference is the ammount of RAM (128M on the A730W vs. 64M on the A730) and the addition of an SDIO internal 802.11b wireless adapter. SDIO is still unsupported [fully] in Linux, with a few companies starting to offer commercial drivers. So, we are waiting for SDIO support to enable internal WiFi.
Internal Flash
The A730(W) has 64 MB of integrated flash memory. With the mphysmap module from mtd you can map two devices at 0x00000000 and 0x0c000000 with a size of 0x02000000 (32MiB) each. The second region holds a partition that is user-writable and called "Flash Disk" in WinCE. Write access maybe should be tested with FFS2 support on that region.
