Allwinner A33 tablets comes with the libdram binary, fortunately I've found the libdram code at https://github.com/realthunder/a33_bootloader/tree/master/basic_loader/bsp/bsp_for_a67.
I've integrated it with mainline u-boot, still lot to do to post it to upstream Basic A33 support including dram init available in my personal repo https://github.com/vishnupatekar/u-boot-sunxi/tree/a33-dram I could able to boot u-boot over fel, and get u-boot command prompt on microSD pins which are multiplexed with UART0. The device page for A33 tablet which I've is here: http://linux-sunxi.org/Softwinner_astar-rda Regards, Vishnu Patekar _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
