# SPIRAM increases the size of the firmware, use -Os to reduce it again to fit in iram
CONFIG_COMPILER_OPTIMIZATION_SIZE=y
esp32/boards: Compile GENERIC_SPIRAM and UM_TINYPICO with -Os. These boards do not build with IDF v4.4 because the section .iram0.text does not fit in region iram0_0_seg. Enabling SPIRAM increases the code size so use -Os instead of -O2 to build these boards. Fixes issue #8260. 2022-04-12 19:44:45 +00:00			`# SPIRAM increases the size of the firmware, use -Os to reduce it again to fit in iram`
