Change flash size of WT32-SC01 Plus

1

So i have a WT32-SC01 Plus with a WT32-S3-Wrover on there and i have that platformio.ini file:

[env:WT32-SC01-PLUS]
platform = espressif32
board = um_tinys3
framework = arduino
upload_speed = 921600
monitor_speed = 115200
;board_build.partitions = no_ota.csv
build_flags = 
	-DARDUINO_USB_CDC_ON_BOOT
	-DLV_CONF_INCLUDE_SIMPLE
	-DLV_COMP_CONF_INCLUDE_SIMPLE
	-DLV_LVGL_H_INCLUDE_SIMPLE
	-DBOARD_HAS_PSRAM
	;-DDEBUG_TOUCH
	-mfix-esp32-psram-cache-issue
	-I src/ui/
	-I src/
lib_deps = 
	SPI
	lovyan03/LovyanGFX@^0.4.18
	lvgl/lvgl@^8.3.2
	; TCA9534
	; Wire
	; DS3231

The flashsize is only 3.3MB or something when i build the whole project:

Flash: [=== ] 25.8% (used 860661 bytes from 3342336 bytes)

but since the WT32 board has 8MB of flash i would like to use them too…
How can i change that?

There are many things being stored in the flash, your application being only a part of it. While you cannot 100% use the flash with your application code, you can chose a different partitioning of the flash per documentation to use it better, e.g., max_app_8MB.csv with

board_build.partitions = max_app_8MB.csv

gives you 7.875 MByte of application space.
