PicorePlayer - how to remore tmpfs / ram disk and boot in normal mode ?

I need to develop some functions to integrate the PicorePlayer with a DAC controller so I would like to work on normal disk / filesystem.

tc@blue:/mnt/mmcblk0p1$ df -k /
Filesystem Size Used Available Use% Mounted on
tmpfs 3.4G 179.7M 3.2G 5% /

After mount /mnt/mmcblk0p1 I can see these files:

tc@blue:/mnt/mmcblk0p1$ cat cmdline.txt
tz=ICT-7 host=blue dwc_otg.fiq_fsm_mask=0xF dwc_otg.lpm_enable=0 console=tty1 root=/dev/ram0 elevator=deadline rootwait quiet nortc loglevel=3 noembed smsc95xx.turbo_mode=N noswap consoleblank=0 waitusb=2


tc@blue:/mnt/mmcblk0p1$ cat config.txt |more
# For more options and information see
