error about compiling the latest code in vscode

[DREAM669]

I downloaded the latest code, but there was an error when compiling in vscode. Can you help me find out the reason?

Executing task: nRF Connect: Build: app/build (active)

This is the compilation of the same scenario in CI: https://github.com/jakkra/ZSWatch/actions/runs/7171094921/job/19525297160

0. Double check you are actually on latest main commit.
1. Run west update
2. Do pristine build instead
3. You have C:/ncs/v2.4.0/zephyr stuff, this is wrong, we use west workspace (zephyr is inside ZSWatch folder) and we use ncs 2.5 (But this should be automatically handled by west, I think)

It's doing: Run west build app --build-dir zswatch_nrf5340_cpuapp@3_debug -p -b zswatch_nrf5340_cpuapp@3 -- -DOVERLAY_CONFIG=boards/debug.conf"

@jakkra Thank you for your answer！The compilation problem is solved. I saw that the latest version adds an external Flash. What is this Flash used for?

@jakkra Thank you for your answer！The compilation problem is solved. I saw that the latest version adds an external Flash. What is this Flash used for?

Mostly for storing image resoucres. The internal flash is 100% full, so external is needed. For example a full screen image is like 20% of internal flash. External flash also allows OTA.
