Need help with understanding partition
Posted: Sun Dec 08, 2019 4:38 am
[UPDATE] The main issue has been solved. I increased the length of factory partition from 1M to 2M. But I still wish to understand the partition table more. Any references? Thanks. Hope this post is useful to anyone else encountering the issue.
I've been using this partition table without enough understanding what it does:
Boot message (repeats):
What I have was a WROOM with 16MB SPI FLASH. I didn't have problems with it. I just upgraded to WROVER-B and compiled a few simple test code and that didn't cause any partition issues. I erased the flash once and that didn't solve the problem.

Code: Select all

# Note: if you change the phy_init or app partition offset make sure to change the offset in Kconfig.projbuild
