For reference please look into the Trats2/Trats code and ./doc/README.gpt As a side note - I'm using following toolchain: CROSS_COMPILE=/opt/eldk-5.4/armv7a/sysroots/i686-eldk-linux/usr/bin/armv7a-vfp-neon-linux-gnueabi/arm-linux-gnueabi- It is 4.7.2 from denx.de. > -- Best regards, Lukasz Majewski Samsung R&D Institute Poland (SRPOL) | Linux Platform Group _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
