I increased it to 4096. Try that and if it doesn't work, just increase it by 100 until it works.

What did you increase the config_main_stack_size to? Since you are using a 32 MBit NAND here, are you setting it to just the 15-bit integer value (32,768) as shown in the other thread? I have a 2 GBit NAND so should I keep the same value?

Yes, that worked. I should have read it a bit more. It's hard to imagine that the file system uses that many function calls. Is there other things that get stored on the stack? Anyway to optimize it?

Focusing on the below lines

[00:00:25.721,801] <err> os: >>> ZEPHYR FATAL ERROR 2: Stack overflow on CPU 0
[00:00:25.721,832] <err> os: Current thread: 0x200009c0 (main)

It looks like you do not have enough stack allocated for this for the main thread.

You need to increase the config_main_stack_size value in your prj.conf as mentioned in this thread.
