This directory contains various scripts that can be used to help development
|
||||
process on the Sony NWZ players. The proper way to use it is to use the Makefile.
|
||||
|
||||
In case of doubt, run
|
||||
make
|
||||
to get the up-to-date documentation.

*****************************
|
||||
Performing a firmware upgrade
|
||||
*****************************
|
||||
|
||||
To perform a firmware upgrade, first copy the firmware upgrade file to the root of
|
||||
the device, and make sure its named
|
||||
NW_WM_FW.UPG
|
||||
Another other name WILL NOT WORK. You've been warned.
|
||||
|
||||
DO NOT FORGET TO UNMOUNT YOUR DEVICE PROPERLY BEFORE DOING WHAT FOLLOWS
|
||||
|
||||
Once once, you need to tell the device to reboot in firmware upgrade mode.
|
||||
At the moment, we only support this operation in UMS/MSC (Mass Storage) mode. So if
|
||||
your device appears as a MTP device, go to the preference settings of your device
|
||||
and make sure your device is set to UMS/MSC or Auto.
|
||||
You need to identify the linux device associated with your device. There are
|
||||
plenty of tutorials on the net on how to do that, you can use mount or dmesg.
|
||||
Assuming the linux device corresponding to your player is
|
||||
/dev/sdx
|
||||
run AS ROOT OR USING SUDO
|
||||
make do_fw_upgrade NWZ_DEV=/dev/sdx
|
||||
|
||||
If everything goes well, the device should reboot and perform the firmware upgrade.
|
||||
|
||||
********************************
|
||||
Building a firmware upgrade that
|
||||
dumps important stuff
|
||||
********************************
|
||||
|
||||
In early development stage, the most useful thing you can do is to dump important
|
||||
stuff from your device:
|
||||
- dmesg and mount output
|
||||
- FU (firmware upgrade) initrd
|
||||
- root FS (file system)
|
||||
We carefully wrote a script that does the following. First make sure that your device
|
||||
has enough free space (at least 300MB to be safe). You need to know the model of
|
||||
your device to build this firmware upgrade. Once you known it, run
|
||||
make list_targets
|
||||
to list all available targets. For example if your targets is one of the
|
||||
NWZ-E460 series, the corresponding target is nwz-e46x.
|
||||
Once you have identified the target. Run
|
||||
make dump_rootfs NWZ_TARGET=nwz-exyz
|
||||
(replace nwz-exyz with your target)
|
||||
This command will produce a firmware upgrade file called
|
||||
dump_rootfs.upg
|
||||
|
||||
In order to run this firmware upgrade, you need to follows the instruction
|
||||
on how to perform a firmware upgrade.
|
||||
|
||||
When performing the firmware upgrade, the script will perform various operation
|
||||
and create several files. Once the "upgrade" is finish and the device has rebooted,
|
||||
you should find the files in the dump_rootfs/ directory at the root of your device.
