[ts-7000] Help in implementing fat16 file system for EP9307

["pritam" <>]

Hi Guys,

I am trying to load linux kernel directly from sdcard without having redboot. I 
have got the sdcard initialization source code working. Now i am trying to 
implement fat16 file system so that I can look for linux kernel file and load 
it. 

I have a working source code for fat16 file system for LPC2148 and i am trying 
to port that to EP9307. But i ran into problem while compiling the source code. 

make
make -C main
make[1]: Entering directory 
`/home/pritam/spi_boot_example/SDcard_bootloader_fat16/main'
arm-linux-gcc -MM -O2 -Wall -fPIC -mcpu=arm9tdmi -I../include -nostdlib head.S

does any one know what this error is. Does any have fat16 file source code 
which is compiled on linux.

Can some one please share some info. 
Thanks
Tama
