BTicino Mamoj board:
===================
Build:
$ make mrproper
$ make imx6dl_mamoj_defconfig
$ make
This will generate the SPL image called SPL and the u-boot-dtb.img.
The following methods can be used for booting Mamoj boards:
1. USB SDP boot
2. eMMC boot (via DFU)
1. USB SDP boot:
---------------
- Build imx_usb_loader
$ git clone git://github.com/boundarydevices/imx_usb_loader.git
$ cd imx_usb_loader
$ make
- Build the BSP and copy SPL, u-boot-dtb.img in imx_usb_loader directory
- Put the board in "Serial Download Mode"
- Plug-in USB-to-Serial, Open minicom 1152008N1 and USB OTG cables to Host
- Turn-on board
- Identify VID/PID using lsusb
Bus 001 Device 010: ID 15a2:0061 Freescale Semiconductor, Inc. i.MX 6Solo/6DualLite SystemOnChip in RecoveryMode
- Update the conf files
imx_usb.conf
0x15a2:0x0061, mx6_usb_rom.conf, 0x0525:0xb4a4, mx6_usb_sdp_spl.conf
mx6_usb_rom.conf
mx6_usb
hid,1024,0x910000,0x10000000,512M,0x00900000,0x40000
SPL:jump header2
mx6_usb_sdp_spl.conf
mx6_spl_sdp
hid,uboot_header,1024,0x910000,0x10000000,512M,0x00900000,0x40000
u-boot-dtb.img:jump header2
- Launch the loader
$ ./imx_usb
We can see U-Boot boot from USB SDP on minicom
2. eMMC boot via DFU:
--------------------
Once booted from USB SDP, program the eMMC as below(make sure to connect USB OTG)
- Change eMMC partition config
=> mmc partconf 2 1 0 0
- Partition eMMC on host
=> ums 0 mmc 2
Host will able to detect the eMMC disk as UMS, partition the same.
- Program SPL
=> setenv dfu_alt_info $dfu_alt_info_spl
=> dfu 0 mmc 2
At Host
# dfu-util -D SPL -a spl
- Program u-boot-dtb.img
=> setenv dfu_alt_info $dfu_alt_info_uboot
=> dfu 0 mmc 2
At Host
# dfu-util -D u-boot-dtb.img -a u-boot
Poweroff and Poweron the board and see U-Boot booting from eMMC.
