Hi,
In which partition you want to flash the kernel, filesystem into eMMC, boot from?

emmc boot0 to boot

Hi,
What's the size of the kernel and filesystem?
Can you not put them in userdata partition?
The boot0 is generally small and may not be adequate for you to store kernel and filesystem.

Please refer this section to know how to write to boot0 partition of eMMC:
