Problems while compiling the project Hello_World

[pyropunx]

I was able to fix this by adding the following lines after the #includes:

Code: [Select all] [Expand/Collapse]

1. #ifndef CHIP_FEATURE_EMB_FLASH
2. /* Chip feature flags, used in esp_chip_info_t */
3. #define CHIP_FEATURE_EMB_FLASH      BIT(0)      //!< Chip has embedded flash memory
4. #define CHIP_FEATURE_WIFI_BGN       BIT(1)      //!< Chip has 2.4GHz WiFi
5. #define CHIP_FEATURE_BLE            BIT(4)      //!< Chip has Bluetooth LE
6. #define CHIP_FEATURE_BT             BIT(5)      //!< Chip has Bluetooth Classic
7. #define CHIP_FEATURE_IEEE802154     BIT(6)      //!< Chip has IEEE 802.15.4
8. #define CHIP_FEATURE_EMB_PSRAM      BIT(7)      //!< Chip has embedded psram
9. #endif

These macros are defined in esp_chip_info.h - no idea why they're not resolving.

I had the same issue when I created a new project from the HelloWorld example. I moved the line "#include "esp_chip_info.h" above the line "#include "freertos/FreeRTOS.h" and this resolved the undefined issue.
