Updating u-boot and file system in u-boot cmd

[JHY]

How can I update u-boot image in u-boot console?

Linux kernel and dtb file are referenced in i.MX_Linux_User's_Guide.pdf, but u-boot image and file system are not.

In addition, SD card can update in host PC, but EMMC can only with MFGtool. Is it right?

[Yuri · Accepted solution]

   U-boot after load is working in DRAM, therefore new updated

version of U-boot may be loaded and written in the same manner as

kernel and dtb. Please refer to ucl2.xml file from MFG what is location

of U-boot image on selected media (SD, NAND).

Note :   MFG is the most preferable way to deploy images.

Have a great day,
Yuri
