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.

Remove 64 bits division into nand driver to compile with an EABI toolchain

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 :

I am also using an EABI compiler (from openembedded) and see these messages (among some other problems):

Philip Balister a ?crit :

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.

Patrice.

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

Philip Balister a ?crit :

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.
