Q: How to fix disk partition alignment to improve SSD life expectancy and performance on Carpo-M

(Menlow) platform under Windows XP

A:

All Windows operating systems before Vista/Win7 use a factor of 512 bytes to create volume clusters. Thus they place

a partition start aligned to 512b sectors and not to 4K sectors. For modern SSD drives, have an internal 4096 bytes

physical sector size and their logic operates 4K chunks of data.

As a result, all logical clusters now linked with two actual physical 4K sectors and all read-write operations will be

multiplied twice. The entire system performance now becomes degraded, as multiple IOPs are required to satisfy

single requests. To handle misalignment, a 4K drive must perform a read-modify-write cycle for every write operation,

resulting in very slow write times and poor performance.

SSD memory cells may degrade after multiple write operations and thereby reduces SSD life time. Partitions

alignment eliminates all redundant read/write operations, thus providing a boost in speed and granting SSD a longer

lifetime.

Solution below fixes the OS stalling and stuttering issue by aligning the system partition and optimizing the Unit

Allocation Size for 4 kilobyte writes. Be sure to backup important data (if any) on your SSD before proceed the

following steps.

1). For system without Windows XP preinstalled

It is first recommended to do a "manual partition alignment" on raw SSD using diskpart tool from Vista/Win7 DVD disc.

Boot with a Vista/Win7 DVD disc from an external optical drive, and you will be taken to the first setup screen.

Press Shift+F10 using an external USB keyboard to open Command Prompt, and run the following sequence of

commands, each line followed by Enter.

diskpart

select disk 0

clean (warning! this removes all partitions on SSD)

create partition primary align=2048 (partition starting offset evenly divisible by 4096 sectors)

Active (assuming you want to install an OS)

format fs=ntfs quick (perform quick format as NTFS partition)

exit

After you are finished, exit diskpart and the command prompt and press power button to force shut down the

computer. You can now do a fresh install of Windows XP onto your aligned partition.

Boot with a Windows XP CD from an external optical drive, F8 key to agree to EULA, Do NOT delete/recreate the

partition in the OS installer (this will kill the alignment that you have performed by diskpart).

Select "C: Partition1 [NTFS]", press ENTER to install and choose "Leave the current file system intact (no changes)"

and continue to finish Windows XP installation.

9

2). For system with preinstalled WinXP hotload

You will need Paragon Alignment Tool for aligning partitions with preinstalled operating system. Follow the on screen

instructions to align the SSD. If boot failed after alignment using this tool, please boot into DOS and use spfdisk tool

to rebuild MBR (spfdisk /mbr).

Aligned partitions achieved better write performance:

Q: Optimizing a SSD Drive for Performance and Longetivity on Carpo-M (Menlow) under Windows XP

A:

1). Disable Drive Indexing

Disabling Drive Indexing can help increase both the performance and longevity of your SSD drive as it prevents

windows from trying to keep track of every file on the drive for search purposes. Drawback is that SSD searches may

be slower.

1. Navigate to My Computer (Computer Shortcut)

2. Right click your SSD's Drive Letter

3. Select Properties, uncheck the Drive Indexing option (Allow files on this drive to have contents indexed in

addition to file properties)

2). Disable System Restore

Disabling System Restore can help to increase the longevity of your SSD drive as well as free up storage space if

existing restore points are deleted. However, if you choose to disable this feature, you should use some other form of

backup, like creating a disk image backup.

1. Navigate to and right click My Computer (Computer Shortcut), select Properties > System Protection

2. Select your SSD Drive Letter and click Configure

3. Check the box to Turn off System Protection (you can also delete existing restore points if you wish)

3). Enable Write Caching

Enabling Write Caching can help to prolong the life of your SSD drive as well as increase it's performance by

decreasing the number of times the drive is accessed by delaying writes until the cache has filled to a certain pont.

Drawback is potential data loss if there is a power outage.

1. Click Start, Type devmgmt.msc and press Enter

2. Click Disk drives to expand

3. Double click your SSD drive and click the policies tab

4. Check the Enable Write Caching on the device box, and click OK

10

4). Disable PreFetch

Disabling Prefetch can help to increase the longetivity of your SSD drive by preventing Windows from storing cached

indexed files in one continuous block on your hard drive, and preventing any defragmeting on that storage area. The

drawback is that it can potentially slow down your system boot.

1. Click Start, type Rededit and press Enter

2. Navigate to Hkey_local_machine\SYSTEM\CurrentControlSet \Control\Session

Manager\Memory Management\PrefetchParameters

3. Double Click Enableprefetcher, and change the hex value to 0 and press OK

4. Close Regedit.

5). Disable Pagefile

Disabling Pagefile can help to prolong the life of your SSD drive and increase it's performance by reducing the amount

of read/write action performed on the drive. This option should be used only if you have a lot of RAM and are running

a 64 Bit Operating System, otherwise it may actually reduce SSD performance.

1. Navigate to and right click My Computer (Computer Shortcut), select Properties > Advanced System

Settings

2. Under the Performance section, Click Settings Button

3. Click Advanced Tab, and under Virtual memory section, Click Change button

4. Uncheck Automatically manage paging file for all drives, and check no paging file, and click Set.

Q: Internal battery not detected or system will shutdown when unplug AC adapter

A: Due to airline safety & security rules for batteries, and also to avoid battery leakage from long term unused storage

situations, by factory default battery detect is OFF.

Remove battery door to adjust the battery detect DIP switch

For normal day-to-day operations of system, please slide the DIP switch from right(off) to left(on). When the battery

detect DIP switch is set as “ON” position, system is powered by internal battery and internal battery can be charged.

Battery detect = OFF (default) Battery detect = ON

Q: Wireless WG7310 buildup from Android source code

A:

Refer “How to Integrated WG73XX and WG75XX with NVS & MAC.pdf” from :

ftp://common:ushare@fae.ubiqconn.com/Carpo_T/Android/WLAN/

Note: tiwlan_cu is replaced by wlan_cu tool in source code provided, hence please use “wlan_cu –b” command

instead.

By original Android source code, the nvs_map.bin containing unique MAC address ID for each system will be

generated under folder “/data/misc/wifi/”. However, please take note that in Ubiqconn’s uImage, WLAN MAC address

is stored differently as /system/etc/firmware/ti-connectivity/wl1271-nvs.bin in android file system.

Hence, in init.rc file, the following modification is done in Ubiqconn’s uImage code:

# WLAN Related services

service wlan_loader /system/bin/wlan_loader \

-f /system/etc/wifi/firmware.bin -i /system/etc/wifi/tiwlan.ini -e /system/etc/firmware/ti-connectivity/wl1271-nvs.bin

#-f /system/etc/wifi/firmware.bin -i /system/etc/wifi/tiwlan.ini -e /data/misc/wifi/nvs_map.bin

Please refer update.sh file in Ubiqconn’s uImage first.

Since wl1271-nvs.bin (or nvs_map.bin) containing corresponding MAC address is unique for each system, so please

make sure to backup this file before updating to new image. wl1271-nvs.bin is backup first and then restored after

uImage update in update.sh (refer Ubiqconn’s uImage update file).

#!/bin/ash

cp /media/mmcblk1p2/system/etc/firmware/ti-connectivity/wl1271-nvs.bin /media/mmcblk1p1/.

cp uImage /media/mmcblk1p1/.

rm -rf /media/mmcblk1p2/*

tar jxvf rootfs.tar.bz2 -C /media/mmcblk1p2/

cp /media/mmcblk1p1/wl1271-nvs.bin /media/mmcblk1p2/system/etc/firmware/ti-connectivity/.

umount /dev/mmcblk1p4

./mkdosfs -F 32 -n data /dev/mmcblk1p4

mount /dev/mmcblk1p4 /media/mmcblk1p4

cp -r Media_Clips/* /media/mmcblk1p4/.

If wl1271-nvs.bin is accidently deleted or lost, you will need to refer section#3 “How to modify MAC address” of “How

to Integrated WG73XX and WG75XX with NVS & MAC.pdf” to generate nvs_map.bin first and manually insert the

MAC address. You will need to disassemble Carpo-T system and the MAC address is shown on the LAN_ID label.

15

Q: On Carpo-T + WinCE6.0 platform, cannot resume from sleep after connection made to GP01/GT01

with GPS/tracker application

A: Because the COM ports used by GPS/tracker module is derived from an USB-to-UART CP2105 chip, so any

GPS/tracker application for WinCE (eg. u-center GPS demo) will need to disconnect from COM port first before enter

suspend sleep mode. Otherwise, CP2105 chip will unable to enter D3 suspend state while COM port is still active

(connected) and subsequently cause hang-up after system resume from sleep.

Since u-center GPS demo application is unable to disconnect automatically from COM port before going into

suspend state, so user will need to manually disconnect COM port first. During similar GPS/Tracker application

development, software developer will need include script for application to able to listen to suspend notify from

system and disconnect corresponding active COM ports before go into suspend mode to avoid such issue.

Q: Dual boot between WinCE 6.0 and Android 2.3 on Carpo-T platform

A: The following is only for Carpo-T system with dual OS (WinCE 6.0 and Android 2.3.4) loaded.

WinCE 6.0 change to Android :

1. Open Command Prompt from Start menu

2. Type in “cd Storage Card2” (go to boot loader partition when a SD card is installed)

Type in “copy MLO_Android MLO” (overwrite existing boot loader and change to Android)

3. Power off and power on system again.

Android change to WinCE 6.0 :

1. Open Terminal from Dev Tools > Terminal Emulator

2. Type in “cd boot” (go to boot loader partition)

Type in “busybox cp MLO_CE MLO” (overwrite existing boot loader and change to WinCE)

3. Power off and power on system again.
