U-Boot

seku — Mon, 22 Oct 2018 18:54:46 GMT

Hi,

We are planning to use MX6/8 processor for our custom board. Need some clarification on u-boot.

The custom board will not have the SD card slot and ethernet board. It has on board EMMC ( 8GB).

- On first boot, Hope the u-boot can be loaded through serial downloader using USB/OTG port.

- Is there any changes required in the imx-usb loader tool?

- We are planning to use different DDR part number. What are all the changes required to load the u-boot using imx-usb loader

- Once the u-boot is up in the RAM, how to program in to on board EMMC. Examples are showing download u-boot, zImage in to DDR using tftpboot and program in to EMMC but in my case, we dont have ethernet nor SDcard.

Thanks,

Senthil

Hi Senthil,

Official tools for downloading image to board is MFG TOOLS, it will use USB OTG port of I.MX6.

you can find OSfirmware path in MFG tools , and in the path, there are u-boot, .dtb , kernel image , rootfs which are used to boot board via USB OTG board.

So it means board can be booted via USB OTG .

please download MFG tools from NXP website, and read related document!

Have a nice day!
