First embedded project. Using the NodeMCU ESP8266 + R307 Fingerprint Sensor + 4-pin I2C 0.96" OLED. Swicthed to PlatformIO VSC from Arduino VSC. At first the code I wrote while using Arduino VSC compiled. Now, after adding more modules, PlatformIO gives the linker error
section `.text1' will not fit in region `iram1_0_seg'
collect2: error: ld returned 1 exit status
while Arduino VSC does not give any errors. Am I good to go? I tried looking up the error, but no luck. My platform.ini is:
[env:nodemcuv2]
platform = espressif8266
board = nodemcuv2
framework = arduino
lib_deps =
adafruit/Adafruit GFX Library@^1.11.9
adafruit/Adafruit SSD1306@^2.5.9
adafruit/Adafruit Fingerprint Sensor Library@^2.1.3
All the headers used (except my own module headers):

While Arduino VSC gives:
