Today I got my new ESP32 WROVER B CPU card and I compile micropython for it, enabling SPI RAM. When trying it, it did not boot saying that the app was too big to fit into the foreseen partition.
When checking the partition table I saw that a hole of 0x10000 was left between factory and vfs (why?)
I increased the factory partition by this amount (0x180000 -> 0x190000) filling the gap.
This fixed the problem.
