Any ideas on what may be > going on? Thanks for reporting this. First of all, please ensure that there is no obvious misconfiguration. For example, whether you have really configured u-boot for Cubietruck. If everything is configured correctly, then it would help a lot to identify which of the await_bits_set() or await_bits_clear() calls is failing in 'arch/arm/cpu/armv7/sunxi/dram_sun4i.c' by adding some extra debugging prints. -- Best regards, Siarhei Siamashka _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
