I am working on a project with VSCode and Platform IO that needs a new partition table. I have copied the partition csv file in the root of the project. When i compile the project i get this error message

enter image description here

This is the partition table that i use

enter image description here

This is my platformIO.ini file

I am not familiar with partition table so i do not know what is wrong here. Can someone help me Thanks in advance

According to the documentation of the esp32doit-devkit-v1 has 4MB of flash memory. Not all of it can be used for your application(s) because bootloader, nvs, phy_config, etc. need someof it. Quoting the from the partition tables documentation the default partition size for an application (e.g. factory or ota_1 or ota_2) is 1M. Seen here in the example for “Factory app, two OTA definitions”

# ESP-IDF Partition Table
# Name,   Type, SubType, Offset,  Size, Flags
nvs,      data, nvs,     0x9000,  0x4000,
otadata,  data, ota,     0xd000,  0x2000,
phy_init, data, phy,     0xf000,  0x1000,
factory,  app,  factory, 0x10000,  1M,
ota_0,    app,  ota_0,   0x110000, 1M,
ota_1,    app,  ota_1,   0x210000, 1M,

Meaning the 1M --> 10124 * 1024 --> 1048576 (Bytes) (refer to your screenshot). The firmware you are building consumes 1060221Bytes which is greater than this (default) partition size...

This is probably due to the fact that in your partition table the size for ota_1 and ota_2 is set to 1984K (1984 * 1024 --> 2031616Bytes) and in combination with the other necessary partitions and the offset due to the booatloader is exceeding the 4MB flash (roughly estimated). I assume a check during the creation of the partition table prevents overuse and sets the partition size back to the default size.

Try to use the following partition table and increase the partition size for ota_1 and ota_2 if necessary

# ESP-IDF Partition Table
# Name,   Type, SubType, Offset,  Size, Flags
nvs,      data, nvs,           ,  0x4000,
otadata,  data, ota,           ,  0x2000,
phy_init, data, phy,           ,  0x1000,
ota_0,    app,  ota_0,         ,  1200K,
ota_1,    app,  ota_1,         ,  1200K,
