How to expand the VIM3 vendor partition size?

VIM3
1

Currently, the vendor partiton is 100% full, I want to copy some files into the vendor at runtime to do some development testing. How can I do?

/dev/block/vendor 248M 248M 0 100% /vendor

HW Info: Khasas VIM3 Basic
OS: the shipped OS from Khasas (Android 9)

Hi, @TonyHo
You can modify the size of the vendor partition in the source code.

diff --git a/kvim3/BoardConfig.mk b/kvim3/BoardConfig.mk
