The H54xx is based on the same PXA250 processor as the H3900 and H1900, but many of the onboard peripherals are different.

The H55xx is the same as the H54xx, except that it uses the PXA255 processor and in some configurations contains 128MB of DRAM instead of 64MB of DRAM.

See H5xxx ASIC Spec for details on the operation of the companion ASIC used in the H54xx and H55xx. The spec for the AK4535 audio codec is also present there. (Added May 21, 2004 by Jamey>

Things that work

• Bootldr works on H5400, except for LCD and PCMCIA/CF, as of 2.19.70.
• Kernel boots to commandline prompt
• PCMCIA/CF works.

      modprobe hci_uart
      hciattach /dev/tts/1 any 921600
  

• 802.11 wi-fi works.
• Touchscreen works.
• LCD works though some further tweaking may be required.
• Front panel buttons work.
• Suspend and resume partly work.
• Battery management and charger work.
• Audio playback and record works. 2003-07-03.

Installing

The H54xx and H55xx are supported by Familiar 0.7.2.

Bootldr does not support the h5000 LCD. When you reset after flashing the bootldr, the machine will vibrate for about a second and then go quiet, but nothing will appear on the display. This is no cause for alarm; connect a serial terminal and proceed with the installation as normal.

Things left to do (in no particular order)

BootBlaster

• Get BootBlaster running on H5400. BootBlaster3900 works on h5400 now.
• Detect H5400 machine type
• Read firmware from H5400 (and pass to bootldr team to disassemble)
• Read all of flash for backup
• Update code to enable VPPEN so flash can be erased and written.
• Write new bootldr to flash.

Bootldr

Known Problems

Bluetooth is not working properly on h5500 for most people. Symptoms include "connection timed out" and H4 errors in the system log.

Other notes

Piotti Piero reports that he got the internal wlan working using these steps:

• modprobe usb-ohci-h5400
• modprobe at76c503-rfmd
• iwconfig wlan0 (your settings)
• ifconfig wlan0 (your settings)
