[U-Boot-Users] EABI problem
Hello,
I am quite new on this mailing list.
I have tried to build u-boot with the last EABI toolchain from codesourcery (arm-2007q1-10 version). It seems that in the file "driver/nand/nand_util.c" there is some 64 bits division which causes a crash during the link process.
bye, Patrice.

Hello,
I am quite new on this mailing list. I have tried to build u-boot with the last EABI toolchainfrom codesourcery (arm-2007q1-10 version).
Which board?
For an AT91SAM9263EK board. I am adding AT91 evaluation kits support to u-boot 1.2.0 and I did some tests which several EABI compiler : codesourcery , open embedded and buildroot. It seems when there is a 64 bits division the compiler refers to "_udivdi3" which is not implemented into "u-boot/lib_arm/" library and then try to link with libgcc from compiler :

Are you compiling a file with a 64 bits division ? I my case it was driver/nand/nand_utils.c enabled by adding "CFG_CMD_NAND" to CONFIG_COMMANDS.

Yes, I have CFM_CMD_NAND set. I can build u-boot for the omap5912osk with the same compiler fine.

Philip
But have you set CFG_NAND_LEGACY flag ? It disables the nand_utils.c compilation and then avoid 64 bits division.
from driver/nand/nand_utils.c #if (CONFIG_COMMANDS & CFG_CMD_NAND) && !defined(CFG_NAND_LEGACY)
I do not see any CFG_CMD_NAND into include/configs/omap5912osk.h file.
