Unlock 512MB?

That's impossible, as the Blade would only be able to access 64 MiB of RAM (remember, all sizes in the datasheet are in bits, not bytes). The Racer's MCP has 2 Gib (256 MiB). As far as RAM is concerned, I don't believe there's anything we can do. As for flash, perhaps we could gain access to the whole 4 Gib (512 MiB), but that might not be such a good idea (think spare sectors).

well played my friend, i missed that part of the BITS!

i was calculating using Bytes

now its for sure that we cant expand the memory any further.

We use all memory...

# df -h

Filesystem Size Used Available Use% Mounted on

tmpfs 82.8M 44.0K 82.8M 0% /dev

tmpfs 82.8M 0 82.8M 0% /mnt/asec

tmpfs 82.8M 0 82.8M 0% /mnt/obb

/dev/block/mtdblock5 220.0M 140.5M 79.5M 64% /system

/dev/block/mtdblock6 162.5M 91.5M 71.0M 56% /data

/dev/block/mtdblock4 37.5M 1.2M 36.3M 3% /cache

220+162,5+37,5+82,8 = 502,8M

+ boot+ recovery = 512M...

There is a lot of space unused in the system partition, same on the cache partition. Has anyone tried using a TPT to repartition the internal memory to get more space for apps? Are there any TPT's for the Racer around?

We will soon publish the manual for partitioned (for gen2 only).

Btw, what about the use free space in the system for swap?

remount system rw

mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
make /system/swapfile right size (32M in example)
dd if=/dev/zero of=/system/swapfile bs=1024 count=32768
check available loopback device
losetup -f
we can see something like
/dev/block/loop0
create a loopback device
losetup /dev/block/loop0 /system/swapfile
make swap
mkswap /dev/block/loop0
swapon =)
swapon /dev/block/loop0
PROFIT!
# free

I'm not really fond of this idea, since it would increase (irreplaceable!) flash wear. Creating a swap file on a memory card is one thing, but doing it on the internal flash? I don't think so... :unsure:

everyone decides for himself ... I think I'll replace the phone before they wear out flash. In addition, the swap is not always used.

Yeah. just read :)

What if we use blade method for our racer?(i know that they mentioned " not for other mobiles")

Will phone be hard bricked?

# df -h

/dev/block/mtdblock3 	12.5M  	1.2M 	11.3M   9% /cache

150+295.9+12.5+81.4= 539.8 MB how can i get 539 if its 512 ?

My partition size is different than yours. Can i increase /system partition by deducting /data as i need more system apps on /system.

Don't count the tmpfs ones. It should be possible to repartition the internal memory in the same way you can for the Blade, Skate, Blade 2. To do so you need to get a Racer TPT and edit some of the files.

why not just make an sd-ext with lets say 256mb ext3?
