4 1. Build your mfgtool image
6 Make sure to enable the following Buildroot options:
8 BR2_PACKAGE_FREESCALE_IMX=y
10 BR2_TARGET_ROOTFS_CPIO=y
11 BR2_TARGET_ROOTFS_CPIO_GZIP=y
12 BR2_TARGET_ROOTFS_CPIO_UIMAGE=y
14 Also modify your kernel configuration to have:
17 CONFIG_USB_MASS_STORAGE=y
19 CONFIG_MMC_BLOCK_MINORS=16
21 2. Go into the output and create the necessary folders
24 $ mkdir -p "Profiles/Linux/OS Firmware/firmware"
26 3. Create your XML update script named ucl2.xml
28 You can find a sample XML at:
30 $ wget https://storage.googleapis.com/boundarydevices.com/ucl2.xml \
31 -O Profiles/Linux/OS\ Firmware/ucl2.xml
33 4. Copy the U-Boot, Kernel and initramfs images to the appropriate
36 $ cp images/u-boot.imx images/zImage images/imx6q-sabrelite.dtb \
37 images/rootfs.cpio.uboot Profiles/Linux/OS\ Firmware/firmware/
39 5. Copy the prebuilt binaries to be flashed
41 Depending on your ucl2.xml file, the sample doesn't flash anything.
43 6. Run the MfgTools client:
45 $ ./host/usr/bin/mfgtoolcli -l mmc -s uboot_defconfig=imx \
46 -s dtbname=imx6q-sabrelite.dtb -s initramfs=rootfs.cpio.uboot \
49 For more information about the tools options, please read the
50 "Manufacturing Tool V2 Quick Start Guide.docx" documentation contained
51 in every mfgtools package from NXP website[1].
53 Note: All the above commands require your Linux host user to have
54 permissions to access the USB devices. Please make sure to have udev
55 rules that allow the user to communicate with the BootROM IDs
56 (Freescale USB recovery) as well as the one used for the UTP Linux
57 image (0x066F:0x37FF). Using 'sudo' in front of the mfgtoolcli
58 command would also grant you the necessary permission but it is *not*
61 Also, if your U-Boot environment doesn't include mfgtools bootargs,
62 make sure to set the following:
64 setenv bootargs "console=${console},${baudrate} g_mass_storage.stall=0 \
65 g_mass_storage.removable=1 g_mass_storage.idVendor=0x066F \
66 g_mass_storage.idProduct=0x37FF g_mass_storage.iSerialNumber=\"\" \
67 g_mass_storage.file=/fat"
