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.
