Hi Roy, I could definitely use such a howto. I have applied the patches to the current mainline u-boot head and try to boot my A13-OlinXino Wifi board in FEL mode. I can compile and boot into u-boot via FEL. However, I get these errors when I have CONFIG_SPL_NAND_SUPPORT defined:
U-Boot SPL 2015.07-rc1-00276-g77792f9-dirty (May 21 2015 - 19:15:54) DRAM: 512 MiB Failed to set core voltage! Can't set CPU frequency sunxi board_nand_init() Nand initialised Error: 1 ECC failures detected Error: 512 ECC failures detected This is my configs/A13-OLinuXino_defconfig looks like this: CONFIG_SYS_EXTRA_OPTIONS="CONS_INDEX=2,AXP209_POWER,USB_EHCI,SYS_MAX_NAND_DEVICE=1,SYS_NAND_BASE=0x00" CONFIG_NAND=y CONFIG_SUNXI_NAND=y CONFIG_SUNXI_DMA=y CONFIG_CMD_NAND=y CONFIG_SPL_NAND_SUPPORT=y CONFIG_SPL=y CONFIG_FDTFILE="sun5i-a13-olinuxino.dtb" CONFIG_USB1_VBUS_PIN="PG11" CONFIG_VIDEO_HDMI=n CONFIG_VIDEO_VGA_VIA_LCD=y CONFIG_VIDEO_VGA_VIA_LCD_FORCE_SYNC_ACTIVE_HIGH=y # For use with the Olimex 7" LCD module, adjust timings for other displays # Set video-mode=sunxi:800x600-24@60,monitor=lcd in the env. to enable CONFIG_VIDEO_LCD_MODE="x:800,y:480,depth:18,pclk_khz:33000,le:16,ri:209,up:22,lo:22,hs:30,vs:1,sync:3,vmode:0" CONFIG_VIDEO_LCD_POWER="AXP0-0" CONFIG_VIDEO_LCD_BL_PWM="PB2" CONFIG_ARM=y CONFIG_ARCH_SUNXI=y CONFIG_MACH_SUN5I=y CONFIG_DRAM_CLK=408 CONFIG_DRAM_ZQ=123 CONFIG_DRAM_EMR1=0 CONFIG_DEFAULT_DEVICE_TREE="sun5i-a13-olinuxino" I just found out in the sun5i-a13-olinuxino.dts file are no nand settings. I guess I can find the information in the linux-sunxi 3.4 kernels fex file for the olinuxio and need to convert to dts, correct? I am happy about any hints / comments.
