work on best low cost mp3 player for rockbox

[bonusbartus]

Maybe I can help out.
I do have lot of resources at the company I work for, so I could ask around and find some chips for you. I would love to get a new rockbox player to be developed... still on my H340 now.

Can someone give me the requirements for a rockbox'able soc?

1) 32bit 100MHz+ reasonable architecture for which there is free compiler
2) external memory interface so you can build system with 4MB+ of ram
3) I2S block or optionaly integrated codec (DAC+output amplifier)
4) serial or parallel lcd interface
5) sd interface for mass storage
6) serial/parallel flash interface for boot memory
7) Documentation available
For this particular application - CHEAP

I'm back. Just get confimed by chip company, ATJ213X is discontinued. Here is everything I can find for ATJ223X. I will keep looking for 213X.

Thanks, interesting reading. Why it is reffered as atj223x while inside there are docs for atj213x?

Just to add that I would definitely buy such a device (or three) were it to be produced.

Hi, I'm interested in your chip. Do your company have a representative or someone I can contact with in China?

Thank you,

As far as I can tell, I only found docs for ATJ atj223x. Which doc did you refer to ?

[wodz]

Archive ATJ223X_LDIII_Firmware_V1.02_1100_100318.rar

For example
usdk213f/psp_rel/include/asm-mips/mach-atj213x/*

register descriptions match atj213x for sure.

Datasheet for atj223x from doc package mostly match that I have for atj213x.

Hi, I confirmed with the manufacturer the docs for 213X and 223X are the same.

ST does have offices in China: http://www.st.com/stonline/contactus/contacts/index.php?type=2#ASIA
There's even a chinese language version of their website: http://www.st.com/web/cn/home.html

This is awesome.  A player built specifically for Rockbox has to be the future of Rockbox.  Otherwise, there is always going to be the problem of the device manufacturer discontinuing the device, just when the bugs in the build for that device are finally getting ironed out.

I can see a lot of potential in a true partnership between the Rockbox community and the device manufacturer.  I'd buy one of these devices in a heartbeat.

I just stumbled in here, and I'll say that i'm scared to death of the click wheel on my Fuze+ finally dying and me losing the best player I've owned (and nearly impossible to replace these days).  So I'd totally be in for some robust and functionally-similar replacement (though i'm fine without the 'wheel' style navigation FWIW).

@Hunterleo: did you happen to review through this older thread?  http://forums.rockbox.org/index.php/topic,6751.0.html  I bring it up only because some users here were able to custom-design their own chipset and (as far as i remember) get something running on it.  Maybe all that is outdated by now (and i note you've been talking with others here far more experienced with this hardware than I am), but maybe worth taking a look still.

WOW. It is quite a long story. Thanks for the info. I will dig into it.
