Where to find Device Configuration Data (DCD) file and Image Vector Table (IVT)?

ozu — Fri, 26 Jun 2015 11:32:20 GMT

I am booting an IMX6 SABRE SD board from QSPI2. Currently, my kernel and rootfs are on SD card and only U-boot in QSPI2.

I want the boot rom to jump to QSPI and copy my custom image from there to RAM. To do this, I understand that I need to make use of IVT and DCD.

But where are these configurations kept?

I must be having it in the IMX6 SDK but couldn't recognize it.

Are there any examples of DCD and IVT for booting from QSPI available?

Please share.

Thanks!

sorry I cant find the mentioned file in U-boot source code.

All I have is compiled .imx variations of u-boot for booting from different devices.

u-boot source from GitHub does not contain a folder for imx6q or imxsx!

Hi Ozu,

You can find all the IVT and DCD related information(header, boot_data structure,..) in the below Freescale's u-boot git repository.

Best Regards,

Yash
