I am working on a port for YP-R0

Anybody who wants to join let me know.
So far I have been able to extract original firmware and found a few places to inject rockbox. Either create a zImage Kernel or try to crack the bootloader to be able to dual boot.

Please let me know if you want to join.

Update could please someone take a look if it is what I think

I have found the follwing usb.sh script with the /usr/local/bin folder of the YP-R0 (I could repack firmware with making this adjustment.)

if [ $1 == "on" ]
then
   lsmod | grep g_file_storage
   if [ $? == 0 ]
   then
      umount /mnt/media1/dev/gadget
   fi

   if [ -d /mnt/media0 ]
   then
      umount /mnt/media1
      umount /mnt/media0
   fi

   lsmod | grep rfs
   if [ $? == 0 ]
   then
      rmmod rfs
   fi

   lsmod | grep g_file_storage
   if [ $? == 0 ]
   then
      #umount /mnt/media1/dev/gadget
      rmmod gadgetfs
      rmmod g_file_storage
      rmmod arcotg_udc
   fi

   lsmod | grep g_file_storage
   if [ $? != 0 ]
   then
      modprobe g-file-storage file=/dev/stl3,/dev/stl2 removable=1
     fi

     echo "OK! USB Connected to /mnt/media0 ! wuwanggood"

elif  [ $1 == "off" ]
then
   lsmod | grep g_file_storage
   if [ $? == 0 ]
   then
      modprobe g-file-storage -r
   fi

   lsmod | grep rfs
   if [ $? != 0 ]
   then
      insmod /lib/modules/2.6.24-445-g48ec830/kernel/fs/rfs/rfs.ko
   fi

   #losetup -o 8192 /dev/loop0 /mnt/media_file/media0
   #mount -t vfat /dev/loop0 /mnt/media0
   mount -t rfs /dev/stl3 /mnt/media0 -o codepage=utf8
   mount -t rfs /dev/stl2 /mnt/media1 -o codepage=utf8

   echo "OK! USB disconnected!"
fi

If I understand right, it checks wether the mp3 Player is connected via USB (I guess another program is invoking the shellscript with argument "on" or "off")
shouldn't I be able to share another drive (which actually is the system drive /dev/stl1) and be able to connect to it.
Of course I would need to create another folder under mount.

Thanks for you help.

Hello Everybody I managed to be able to run scripts on my YP-R0
Its still original Firmware (but firmware is linux) I can run every script I would want to.
I would need you guys to maybe give me some input on which information is mandatory for a successful rockbox port.
I did alter the original firmware and flashed it back!
The first script I ran was :
cat /proc/cpuinfo

Chronon:
Here's the port page:
http://www.rockbox.org/wiki/SamsungYP

If you don't get responses here you can try posting in the IRC channel too.  Most developers seem to spend more time there than on the forums.

I think slade is the author of that wiki page...

@slade:
You should try to build your own kernel and bring it onto the device. Try to get the kernel config and the kernel source code. There should be something on samsungs open source page.

I don't know if its needed to replace that linux. Maybe there can be a rockbox as an application solution as like as on android.

Chronon:
I believe so.  I was more posting it for others since it didn't have a link in this topic yet.
