I'am using a board similar to at91rm9200ek, u-boot version is v2011.03.
Is your code in mainline? Which board configuration si this?
my code not in mainline, but I test it using the code for at91rm9200ek
Early I use eldk4.2 to build u-boot, all things ok, but eldk 4.2 can't compile busybox whith ubiattach enabled. So I change my toolchain to
Really? What are the exact problems? [Please post this on the ELDK mailing list.]
Yes, it was. I will sent the error message to ELDK mailing list
eldk5.0 (eldk-eglibc-i686-arm-toolchain-gmae-5.0.tar.bz2, poky-image-sato-sdk-armv5te.tar.gz). Now the make process all ok. But when download u-boot.bin to the board. the code say:
-F- Undef detectedIs this the exact error message? And it gets printed by U-Boot? Problem is, I cannot find any such text in mainline U-Boot.
The message is printed after uboot.bin downloaded by my preloader, Maybe this message was printed by the preloader code after it jump to uboot. In my preloader some exception vector were setted to print message. So it seems uboot.bin had some illegal asm code in it.
eldk5.0-armv5te CAN'T used for arm920t ??? Is this true?
The AT91RM9200 uses a ARM920 core, i. e. it belongs to the ARM9TDMI family, ARMv4T architecture.
As the tool chain name "armv5te" clearly suggests, this is configured for the ARMv5TE architecture (for example ARM9E, ARM10E, XScale families).
So yes, this is configured for a more advanced architecture. OTOH, if you provide correct compiler options, it should still work for U-Boot. But the, I don't know your code...
My code is exactly same for at91rm9200ek at version v2011.03
So what compiler options should be use? I notice some u-boot compile commandline has option '-march=armv4'. Why with this option it is still generate wrong code
