#6884

Important

Before each release, this NVS test needs to be locally builded + run on ESP32S3 with Octal Flash.

Command to build with custom FQBN (cfg.json will be excluded from building):
./.github/scripts/tests_build.sh -s nvs -t esp32s3 -fqbn espressif:esp32:esp32s3:PSRAM=opi,USBMode=default,PartitionScheme=huge_app,FlashMode=opi

Command to run:
./.github/scripts/tests_run.sh -s nvs -t esp32s3 -e -o

@P-R-O-C-H-Y flash modes are working now in the 4.4 branch. You can test against that and master if you want to verify that it fails on one, but not the other. cc: @Ouss4

@me-no-dev Can confirm that on C3 and S3 all modes are again working on idf-release/v4.4 branch. Great job!

FQBN Additions:

• ESP32-S3: FlashMode=[qio|qio120|dio|opi]
• Rest: FlashMode=[qio|qout|dio|dout],FlashFreq=[40|80]

[me-no-dev]

There is a problem with the test @P-R-O-C-H-Y . Since the value is in NVS, it is probably already set to something from previous run and will never again start from 0, so what the test expects will fail (as it did). Maybe you need to rethink the test or find a way to erase flash prior to running the test.

[P-R-O-C-H-Y]

We are waiting for @Ouss4 to make a PR with a few CI changes. One will be the flash erase so the test will work after that PR ;)

Not to derail this pr, but is there actually eqpt out there that will only run on dout/qout?

yes. I have a board that has flash which can do only dout. It's very rare, but exists and also can free up some IO if you do not need the throughput.

Ok, just asking. I have some cheap sh!t in my bin, and I've never seen it 😄
