eMMC update on CL-SOM-IMX8?

[byunggukchoi]

I bought a CL-SOM-IMX8 reference board.

And I'm trying to update kernel on u-boot but I don't know the exact block number for kernel image and dtb to locate in MMC.

In the following command, 0x5000 for kernel image and 0xE000 for dtb are arbitrary block numbers.

I want to know the exact block number instead of 0x5000 and 0xE000 for kernel and dtb.

u-boot=> tftp 0x40480000 Image

u-boot=> tftp 0x43000000 cl-som-imx8.dtb

u-boot=> mmc write 0x40480000 0x5000 0x9000

u-boot=> mmc write 0x43000000 0xE000 0x800

Thanks in advance.
