How to WOL:
1. Python2
#!/usr/bin/env python2
import socket
import time

bcast_addr = '192.168.88.255' # broadcast address for you network
target_mac = "4C:E6:76:E7:xx:xx" # colons are optional, case does not matter

mac = target_mac.replace(':', "")
mac_bytes = "".join([chr(int(mac[i:i+2], 16)) for i in range(0, len(mac), 2)])
WoL_packet = '\xff'*6 + mac_bytes * 16

s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)

while 1:
    s.sendto(WoL_packet, (bcast_addr, 9))
    print "Sent paket!"
    time.sleep(180)
2. ArchLinux

  • pacman -S wol

3. dd-wrt router
  • Administration -- WOL -- Manual WOL, with port 9
4. Windows

Flash/Upgrade Palm M500 M505 ROM in windows7

Palmm500_eng4_1_FlashNew.exe and Palmm505_eng4_1_FlashNew.exe doesn't work well in windows OS after XP, software can not detect debug mode handhold.

But the ROM imager in ROM Crafter from Brayder Technologies can be used for backup and flash/upgrade the OS.

4.1OS can be extracted from Palmm500_eng4_1_FlashNew.exe and Palmm505_eng4_1_FlashNew.exe.

Firstly install Palmm500_eng4_1_FlashNew.exe and Palmm505_eng4_1_FlashNew.exe.
Then decompress ROMIMAGE10000 from C:\Program Files (x86)\Handspring\Palmm500_ENG_FlashTool.exe\.rsrc\BINARY_DATA\

ROMIMAGE10000 is ROM file can be flashed by ROM imager.

Related files can be downloaded from internet or contact me.

FYI, if flash fail or report "handheld memory locked", use jackflash to release flash memory firstly.

Fix/Debug Pogoplug v4 arch linux boot failure

Recently, after upgrade archlinux on Pogo, system failed to boot up.
Even fresh install can't fix this problem.

required:
netconsole uboot installed on pogoplug v4.


Debug:
1.  setup netconsole and monitor uboot :
xterm1: nc -l -u -p 6666
xterm2: nc -u 192.168.1.10 6666

looks like kernel booted successfully.

2. printenv in uboot

Pogov4>

3. Enable netconsole for linux kernel
Pogov4> setenv set_bootargs_mmc 'setenv bootargs root=$mmc_root rootdelay=$rootdelay rootfstype=$rootfstype $mtdparts [email protected]/,[email protected]/'
Pogov4> saveenv

4. continue monitor linux kernel netconsole output
OUTPUT INDICATE NEW KERNEL NEED EXT4 ROOTFS!

5. fix pogo by format SD card with mkfs.ext4 -j /dev/sdb1, then fresh tar -xvzf Archlinux -C /mnt/alarm

6. retry and monitor kernel netconsole output
STILL REPORT NEED EXT4 ROOTFS

7. set uboot parameter:
Pogov4>setenv rootfstype ext4
Pogov4> saveenv

8. retry reboot
BOOT SUCCESS!

7. close kernel netconsole and change bootargs back to normal.
Pogov4> setenv set_bootargs_mmc 'setenv bootargs console=$console root=$mmc_root rootdelay=$rootdelay rootfstype=$rootfstype $mtdparts'
Pogov4> saveenv
