OMAPL137 EVM：Transfer Data in Nand to Host

Hi,

I'm using OMAPL137 EVM along with UI Module, both are from Spectrum. The kernel is Montavista linux 2.6.33. The file system is jffs2. The kernel is put into spi flash and the file system is put into nand flash on the UI card. In my project, the Nand flash is used to store data files. 

when booting, I use the following args:

setenv bootargs 'mem=32M console=ttyS2,115200n8 root=/dev/mtdblock3 rootfstype=jffs2 rw rootwait'
setenv bootcmd' sf probe 0; sf read 0xc0700000 0x80000 0x220000; bootm 0xc0700000'

This args load kernel image from SPI flash into RAM addr and mount the file system in NAND.

Now I'm wondering is there some way to transfer the data files(like .txt or .bin files) stored in nand flash to a host machine(VMplayer linux or windows PC)?

PS :My project is developing an measuring equipment. It uses OMAPL137 as the controller, collects data from some sensors and stores them at nand flash. When the equipment done the measurement, I need to read these data(hundreds MBytes) out through Ethernet cable.

Thanks,

Ming
