1BTicino Mamoj board: 2=================== 3 4Build: 5 6 $ make mrproper 7 $ make imx6dl_mamoj_defconfig 8 $ make 9 10 This will generate the SPL image called SPL and the u-boot-dtb.img. 11 12The following methods can be used for booting Mamoj boards: 13 141. USB SDP boot 15 162. eMMC boot (via DFU) 17 183. Falcon mode 19 201. USB SDP boot: 21--------------- 22 23 - Build imx_usb_loader 24 25 $ git clone git://github.com/boundarydevices/imx_usb_loader.git 26 $ cd imx_usb_loader 27 $ make 28 29 - Build the BSP and copy SPL, u-boot-dtb.img in imx_usb_loader directory 30 31 - Put the board in "Serial Download Mode" 32 33 - Plug-in USB-to-Serial, Open minicom 1152008N1 and USB OTG cables to Host 34 35 - Turn-on board 36 37 - Identify VID/PID using lsusb 38 39 Bus 001 Device 010: ID 15a2:0061 Freescale Semiconductor, Inc. i.MX 6Solo/6DualLite SystemOnChip in RecoveryMode 40 41 - Update the conf files 42 43 imx_usb.conf 44 0x15a2:0x0061, mx6_usb_rom.conf, 0x0525:0xb4a4, mx6_usb_sdp_spl.conf 45 46 mx6_usb_rom.conf 47 mx6_usb 48 hid,1024,0x910000,0x10000000,512M,0x00900000,0x40000 49 SPL:jump header2 50 51 mx6_usb_sdp_spl.conf 52 mx6_spl_sdp 53 hid,uboot_header,1024,0x910000,0x10000000,512M,0x00900000,0x40000 54 u-boot-dtb.img:jump header2 55 56 - Launch the loader 57 58 $ ./imx_usb 59 60 We can see U-Boot boot from USB SDP on minicom 61 622. eMMC boot via DFU: 63-------------------- 64 65 Once booted from USB SDP, program the eMMC as below(make sure to connect USB OTG) 66 67 - Change eMMC partition config 68 69 => mmc partconf 2 1 0 0 70 71 - Partition eMMC on host 72 73 => ums 0 mmc 2 74 75 Host will able to detect the eMMC disk as UMS, partition the same. 76 77 - Program SPL 78 79 => setenv dfu_alt_info $dfu_alt_info_spl 80 => dfu 0 mmc 2 81 82 At Host 83 84 # dfu-util -D SPL -a spl 85 86 - Program u-boot-dtb.img 87 88 => setenv dfu_alt_info $dfu_alt_info_uboot 89 => dfu 0 mmc 2 90 91 At Host 92 93 # dfu-util -D u-boot-dtb.img -a u-boot 94 95 Poweroff and Poweron the board and see U-Boot booting from eMMC. 96 973. Falcon mode: 98-------------- 99 100 - Skip 10M space and create dual partitions for eMMC, start sector is 20480 101 102 Partition Map for MMC device 2 -- Partition Type: DOS 103 104 Part Start Sector Num Sectors UUID Type 105 1 20480 131072 c52e78be-01 83 106 2 151552 7581696 c52e78be-02 83 107 108 - Write uImage 109 110 => fatload mmc 2:1 $kernel_addr_r uImage 111 => mmc write $kernel_addr_r 0x1000 0x4000 112 113 - Write dtb and args 114 115 => setenv bootargs console=ttymxc2,115200 root=/dev/mmcblk0p2 rootfstype=ext4 rootwait rw quiet 116 => fatload mmc 2:1 $fdt_addr_r imx6dl-mamoj.dtb 117 => spl export fdt $kernel_addr_r - $fdt_addr_r 118 => mmc write 0x13000000 0x800 0x800 119 120 Poweroff and Poweron the board and see Linux booting directly after SPL. 121 122-- 123Jagan Teki <jagan@amarulasolutions.com> 12403/12/18 125
