Memory related issue



  • I am using M5Stack-Core_esp32 . compiler arduino.
    when i compile my program it is showing that "sketch uses 1460566 bytes (111%) of program storage maximum is 1310720.
    I have used OTA code , BLE and uart. How can i increase program memory. It is suppose to be 2MB.
    It is showing only 1.25MB.

  • from http://desire.giesecke.tk/index.php/2018/01/30/change-partition-size/

    inside ..esp32\tools\partitions add new file for e.g. bigapp.csv with content:

    # Name,   Type, SubType, Offset,  Size, Flags
    nvs,      data, nvs,     0x9000,  0x5000,
    otadata,  data, ota,     0xe000,  0x2000,
    app0,     app,  ota_0,   0x10000, 0x1E0000,
    app1,     app,  ota_1,   0x1F0000,0x1E0000,
    eeprom,   data, 0x99,    0x3F0000,0x1000,
    spiffs,   data, spiffs,  0x3F1000,0xF000,
    

    and inside esp32\boards.txt add new(copy) board like:
