Sony NWZ-S540


Overview

This is the page for the Sony NWZ-S540 series (NWZ-S543, NWZ-S544, NWZ-S545)

Port status

There is no Rockbox port for this player

I uploaded a copy of the original firmware v1.0.1 here: firmware.sb

The patch tracker contains some incomplete port. The missing part is the raw nand flash. Since there is no sdcard slot and no plan to support to the raw nand flash, we do not plan to finish this port.

Hardware

The Sony NWZ-S540 features 12 hardware buttons: power/option, play/pause, left, right, up, down, home/back, volume up, volume down, hold, speaker/earphones, reset.

Chip labels: 9VAI8 NWI79 G8KB?

98or 9B 2113A

STMP3780 A3PTX? A00941AU? TAIW

9UAI7 D9FRN? FORK MT

STFM1000 B2 FNUB DHRNA

Recovery Mode

One can reach the recovery mode by powering off the unit and plug the USB cable while holding the power button. There are two other alternative methods:
  • power on the player (without USB cable plugged), hold power and plug the USB cable while holding power for at least one or two seconds
  • plug the USB cable, hold power and press the reset button while holding power for at least one or two seconds

B2P03 IN Used to determine device variant
B2P04 IN Used to determine device variant

Device variant are as follows (see section below for comment):
B2P04 B2P03 Device
0 0 NWZ-E340
0 1 NWZ-E440 or NWZ-E440K
1 0 NWZ-BB
1 1 NWZ-S540

Models

Apparently the same firmware is used for several players. The model is determined from two pins and/or the MMC. The following players are handled: E340, E360, E440, E440K?, S540, BB. This is just a wild guess and it does not mean in any way that one can take the OF from one and put it on the other, there might be other differences.
