I agree ...

Finding the datasheet for the SA58700 CPU would be a great help to the project.

The datasheet would give us important details such as the addresses of the various I/O registers, memory controller, etc.

Erm.. I might be able to do something.. I'm familiar with embedded systems programming, c, c++, assembly.. i've been working with ARM cpu's like philips lpc2106 etc.. writing (simple) drivers for i2c, spi, shift registers, lcd's etc.. i've been digging into embedded os development in the past, created an ultra simple scheduler and all..
The thing is.. I need something to get started.. is cross compiling with gcc possible? Is there a way to JTAG the meizu m6 or are we always in danger of killing the m6 by a simple programming error in the firmware?
Not to mention development.. is there any SVN or CVS tree or something? Being there's already some work that has been done

An important step would be to figure out how to do DFU in Linux. So far I've been unsuccessful. I think it would speed up development by *a lot* if we can do a DFU restore in Linux.

hi!

@ dimap
could you give as a report here from time to time what's going on in the russian forum please? i think there are many people here who are waiting in suspence to get a rockbox build for the m6

best

Hi.
If you want to get into the development, you should probably try to contact markun over at rockbox.org - it looks like he doesn't check over here very often. He already started to do something, although I am not concerned with what he've done. You might want to check the wiki on rockbox.org, espacially MeizuM6Port < Main < TWiki although it seems a little bit outdated.

You can not brick your Meizu because it has a build in DFU recovery mode, wich runs in an special part of the memory (I guess, I don't know jack about embedded). There are many topics about recovering your Meizu around here.

Yeah, it looks like you can't brick the Meizu. I already knew about the dfu mode, but I wasn't sure that it was an absolutely failsafe backup for bad flashes. The spec over at the Meizu section of Rockbox, lists it as having 50kb of boot ROM. If you don't know what a ROM is, it's a type of memory that can't be overwritten. That's a relief!
