Error `psram: Not a valid or known package id: 6` on ESP32-PICO-MINI-02

I have an Adafruit ESP32 Feather V2 with an ESP32-PICO-MINI-02 and am getting an error / boot loop when trying to run the example:

So far I have

• Set the target to xtensa-esp32-espidf to match the μC on the module
• Added --use-stub to the runner setting to get it to upload at all
• Updated the esp-idf-sys and embuild versions to their current version
• Set ESP_IDF_VERSION to release/v5.0 (incl. setting the rustflags and doing a cargo clean)
• Added the following to sdkconfig.defaults

  CONFIG_SPIRAM=y
  CONFIG_SPIRAM_TYPE=SPIRAM_TYPE_AUTO # since the documentation is unclear, I also tried CONFIG_SPIRAM_TYPE_AUTO=y
  CONFIG_SPIRAM_CACHE_WORKAROUND=y

All to no avail, as I keep getting that error. The board itself (still) works fine with Arduino

hey i had the same problem, resolved by running the latest espflash from git (seems like there's a flash stub update or something)

Thanks for the hint! Installing espflash 2.0.0-rc.3 instead of the stable 1.7.0 and replacing espflash --monitor in .cargo/cargo.toml by espflash flash --monitor solved the issue for me
