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.
