Rockbox Development > New Ports
SAMSUNG YH-920
pyro_maniac:
The rockbox files didn't create a tmp folder.
I copied all files of a H10 5G Build into the system folder and in the root folder, created a tmp folder on both directories and started the player but there happened nothing new.
/EDIT: And i had a file 7 on the device for firmware.
/EDIT2: After this test, i had to rebuild my device completly. I don't know why.

If you are really serious about porting rockbox to the YH-920, it won't have been the last time you completely re-built your device :D
You need to put together a new build, starting with an existing one which allows at least harddisk and display access, otherwise it's going to be pretty difficult to get anywhere. The existing H10 build provides a good starting point (PP5020 player), but in my previous thoughts I made a mistake with the display, so you could not see anything. Here are my findings:
1. LCD:
I could find "S4E1 5002" on the plastic stripe, which means that according to this it is
identical to the LCD used in Iriver H1xx .
2. Power chip Linear LTC3455
also used in Meizu M6, you might re-use some drivers from there.
3. Audio AKM AK4537VN
I could not find any other player with this component, so here you have to start from zero. Seems to be well documented, however.
4. mi4 format
The header of the two most recent Samsung mi4-firmwares seem to fully comply to the 01020100 "standard" as indicated here, without the exception at 0x18 , which only existed for the earlier two firmwares.
If you would like to continue (but pls consider if it's worth it, I won't be able to help significantly), read here and there, setup your development environment, start with the H10 5GB port, replace the display driver with (hopefully) an appropriate one from H1x0, and watch, smell, and listen. Good luck!

how can i change the powerchip in a h10 build to a meizu powerchip?
wolly-p:
Did you check what happens in 'config-meizu-m6sl.h' and related files? You can also ask in the Meizu M6 forum thread. For he first tries, just comment it out or leave as it is if you do not find anything particular to the LTC3455.

Yes i made a diff of both configurations. After that, i tried to learn something more about the structure. I thought that i only have to change the small part for the power chip but its much more different.Yes i made a diff of both configurations.

I thought that i only have to change the small part for the power chip but in the meizu firmware the powermanagment seems not to be separated.
Maybe i will ask in the meizu thread later on. First i will try on my own.
