Experimenting with the pit-file

We know that Samsung devices uses a pit file to partition the device, its very helpful the device have a ext4 brick, so WhiteXP from XDA-dev, said that CWM 6.x needs 1mb more to run on the Galaxy Y,


so Mohamed Anwar from XDA, customized the pit file to increase the boot-partition up to 9,75mb. This is the next step for building recoveries for the Galaxy Y

Analyze the Block Diagramm by Samsung

So, I sent 3 more invites for our blog and saying lets make a good start for galaxy Y Researching,
lets improve our information about the Galaxy Y

So we all know that the Galaxy Y have a bcm21553 with VideoCore IV

Download Link for Samsung Service Manual (official Odin flashing Tutorial inside)

http://bit.ly/Xxqu7j

Lets analyze the Block Diagram inside (in the Service Manual)

first we begin with the SoC

we see, a bcm21552 / B0 chip, but i think there is a type error, bcm21553 is mean.
And, have a ARM1136 Processor with 832 MHz


The Camera is able up to 8M pixel, and system can play 30fps H.264, MPEG-4, H263 and WMV9
and play MP3, AAC, AAC+, EAAC, WMA, AMR-NB and AMR-WB

It have a USB-OTG HS with 480 Mbps and Stereo DAC


The GPS Name is the bcm4751
The Wifi/BT/FM name is the BCM4330 (thanks to WhiteXP in XDA to fixing Wifi issue in CM7)
So, the SIM Card have 1.8V/3.0V support
The Memory is a KAT007012B-BRTT and have a NAND with 4Gbit + DDR with 3Gbit

The RF Block is a BCM2091 and have a Inantenna

The Galaxy Y have a 2M FF SF Sensor (i think this is the cam)

The display have a 320*240 (2,98") Resolution with QVGA TFT

so, you can read the block diagram yourself and read more information


thanks for reading
