Configuring the ESP-WROVER-KIT v4 board

Before we compile and flash our program to the ESP32 board, we should configure our project. In this section, the ESP32 board model is ESP-WROVER-KIT v4. We configure the LCD model and flash size using menuconfig. To do so, follow these steps:

1. Open the Terminal and navigate to your project folder.
2. Run menuconfig by typing the following command:

$ make menuconfig

1. Select 4 MB for flash size.
2. Save this configuration.
3. Select Exit to quit menuconfig.

After we run menuconfig, we will get a config file, sdkconfig, as shown in Figure 2-13. Open this file and ensure that this config has a value of CONFIG_SPIFFS_BASE_ADDR= 0x180000. If you have a value 180000 on that config, you should change it to 0x180000:

Now, your program is ready to compile and run in the next section.
