Fail to build in step 2: cannot move location counter backwards (from 20090e84 to 20040000)

Running on Adafruit Feather RP2040 Adalogger

In step 2, when I try to build, the following error comes up after reaching 100%

It seems to be some kind of memory issue, since nothing has been added yet, not really sure what can possibly be wrong.

Update:
Tried w/ Pico board, got same result. default_toolchain: rpipico

Hello,

Was anything in the config/ directory changed? Did you copy the config/ directory from fprime/config/ or another source?

[yudataguy]

copied config directly from fprime/config as suggested, i'll try not copy later today

Use the config/ from the deployment cookiecutter since the default fprime/config/ is too large for majority (if not all) of the Arduino boards after the recent updates.

I will update the tutorial docs to reflect this.

updated settings.ini

After I copied VersionEnumEnumAc.app and VersionEnumEnumAc.hpp to LedBlinker/config folder, this error was gone, but errored without any obvious error

Try copy the LedBlinker/config/ directory into the project root instead, and change the settings.ini to be

config_directory: ./config

[yudataguy]

Thank you. It finally worked. Why would have the same files, but different directory causing different behaviors?

[ethancheez]

build cache seems to always place the config/ path under build-fprime-automatic-x instead of build-fprime-automatic-x/LedBlinker, hence why the include path couldn't be found.

I'm not sure the reasoning behind this.. probably some underlying linking stuff FPrime is doing within their cmake files.

@LeStarch is this a bug? Or were custom config/ files not intended to go in other file paths other than the project root?

[LeStarch]

Configs must be synonymous with a project. This is because it is invalid to have different configs between different items in the same build. A build and a project are one to one.

[LeStarch]

That being said, configs should be allowed to be placed anywhere in a project. That bit might be a bug.
