General issue report

Hello All,

I'm trying to add support for multiple ESP32 modules to a project, but when compiling, it does not select the right partition.csv file. This is what I did:

/led
  /main
    - main.c
  /partitions
    - partitions_esp32.csv
    - partitions_esp32s2.csv
    - partitions_esp32c3.csv
    - ...
  - CMakeLists.txt

Added this to main.c

#ifdef CONFIG_IDF_TARGET_ESP32
  // ESP32-specific code
#elif defined(CONFIG_IDF_TARGET_ESP32S2)
  // ESP32-S2-specific code
#elif defined(CONFIG_IDF_TARGET_ESP32C3)
  // ESP32-C3-specific code
#elif defined(CONFIG_IDF_TARGET_ESP32S3)
  // ESP32-S3-specific code
#elif defined(CONFIG_IDF_TARGET_ESP32C2)
  // ESP32-C2-specific code
#elif defined(CONFIG_IDF_TARGET_ESP32C6)
  // ESP32-C6-specific code
#elif defined(CONFIG_IDF_TARGET_ESP32H2)
  // ESP32-H2-specific code
#elif defined(CONFIG_IDF_TARGET_ESP32P4)
  // ESP32-P4-specific code
#elif defined(CONFIG_IDF_TARGET_ESP32C5)
  // ESP32-C5-specific code
#endif

Added this to CMakeLists.txt

if(CONFIG_IDF_TARGET STREQUAL "esp32")
  message(STATUS "Using partition table for ESP32")
  set(PARTITION_TABLE_DEFAULT "partitions/partitions_esp32.csv" CACHE FILE "Default partition table file")

endif()
message(STATUS "Partition table file: ${PARTITION_TABLE_DEFAULT}")

In menuconfig, didn't change anything left default.

Steps:

1. idf.py set-target esp32c3
2. idf.py build
3. Logfile: log.txt

Specific partition settings must be written in sdkconfig.defaults.

This will help.

@nopnop2002 Thank you for your reply. But with the solution you provided, it doesn't fix my problem, because I define only one of the *.csv files and need to change the sdkconfig.defaults every time I want to compile for another ESP module?

[nopnop2002]

sdkconfig.default can be created for each target.

@nopnop2002 Thank you that did the trick!
