Modify and Build U-boot
Yocto 2.1
You can download patch file as below:
File:Bypass_advloader_Yocto_2.1.patch
build u-boot (we take DDR 1G for example)
make mx6qrom5420b1_1G_defconfig make u-boot.imx -j4
Then you can put this file to mfgtool folder
Modify mfgtool
- ucl2.xml
We add a new task for burning u-boot.imx to spi
<LIST name="ADV bypass adv-loader" desc="update u-boot.imx to spi">
<CMD state="BootStrap" type="boot" body="BootStrap" file ="firmware/u-boot.imx" ifdev="MX6Q">Loading U-boot</CMD>
<CMD state="BootStrap" type="load" file="firmware/uImage" address="0x12000000"
loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" ifdev="MX6Q">Loading Kernel.</CMD>
<CMD state="BootStrap" type="load" file="firmware/initramfs.cpio.gz.uboot" address="0x12C00000"
loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" ifdev="MX6Q">Loading Initramfs.</CMD>
<CMD state="BootStrap" type="load" file="firmware/imx6q-%board%.dtb" address="0x18000000"
loadSection="OTH" setSection="OTH" HasFlashHeader="FALSE" ifdev="MX6Q">Loading device tree.</CMD>
<CMD state="BootStrap" type="jump" > Jumping to OS image. </CMD>
<CMD state="Updater" type="push" body="$ flash_erase /dev/mtd0 0 192">Erasing SPI</CMD>
<CMD state="Updater" type="push" body="send" file="files/u-boot.imx" ifdev="MX6Q">Sending u-boot.imx</CMD>
<CMD state="Updater" type="push" body="$ dd if=$FILE of=/dev/mtd0 bs=512 seek=2">write u-boot.imx</CMD>
<CMD state="Updater" type="push" body="$ echo Update Complete!">Done</CMD>
</LIST>
- cfg.ini
[LIST] name = ADV bypass adv-loader
At last , we can refer to Mfgtool to update spi.
