Hi all, I am having ARM Board On which i am trying to enable FAT file system awareness in U-boot. And in U-Boot Source code that module is already present. i am having LPC2294 Arm core in which i am having 256kb on chip flash memory and 16 kb on chip RAM. and apart from that i am having 4MB external flash memory and 2 MB external RAM. The U-boot is already ported to this board. flash support , memory commands support,are there currently but the hex size becomes 338 k. and when i enable the FAT filesystem support from my boards header file by defining the

#define CONFIG_COMMANDS ( \ (CONFIG_CMD_DFL & ~CFG_CMD_NET & ~CFG_CMD_IMI & ~CFG_CMD_LOADS & ~CFG_CMD_MISC \ & ~CFG_CMD_BDI & ~CFG_CMD_BOOTD & ~CFG_CMD_CONSOLE & ~CFG_CMD_ENV & ~CFG_CMD_IMLS \ & ~CFG_CMD_AUTOSCRIPT & ~CFG_CMD_RUN & ~CFG_CMD_ITEST & ~CFG_CMD_FPGA \ & ~CFG_CMD_SETGETDCR) | ( CFG_CMD_FAT ) ) but while compiling i am getting error

make[1]: Leaving directory `/try/u-boot-1.1.4/common' UNDEF_SYM=`arm-elf-objdump -x lib_generic/libgeneric.a board/phytec/libphytec.a cpu/arm7t/libarm7t.a lib_arm/libarm.a lib_arm/libLPC22xx.a fs/fat/libfat.a drivers/libdrivers.a post/libpost.a post/cpu/libcpu.a common/libcommon.a |sed -n -e 's/.*(__u_boot_cmd_.*)/-u\1/p'|sort|uniq`;\ arm-elf-ld -Bstatic -T /try/u-boot-1.1.4/board/phytec/u-boot.lds-Ttext 0x81040000 $UNDEF_SYM cpu/arm7t/start.o \ --start-group lib_generic/libgeneric.a board/phytec/libphytec.a cpu/arm7t/libarm7t.a lib_arm/libarm.a lib_arm/libLPC22xx.a fs/fat/libfat.a drivers/libdrivers.a post/libpost.a post/cpu/libcpu.a common/libcommon.a --end-group -L /usr/local/arm-uclinux-tool/lib/gcc/arm-uclinux/3.4.3/msoft-float -lgcc \ -Map u-boot.map -o u-boot /usr/local/arm-uclinux-tool/bin/arm-elf-ld.real: region ram is full (u-boot section .bss)

so if anybody know's about this please guide me so that i can enable the fat support.

Thanks and regards Harshal shete
