choice ESPTOOLPY_FLASHFREQ prompt "Flash SPI speed" default ESPTOOLPY_FLASHFREQ_80M config ESPTOOLPY_FLASHFREQ_120M bool "120 MHz (READ DOCS FIRST)" depends on (SPI_FLASH_HPM_ON || ESPTOOLPY_OCT_FLASH) && \ (ESPTOOLPY_FLASH_SAMPLE_MODE_STR || IDF_EXPERIMENTAL_FEATURES) help - Optional feature for QSPI Flash. Read docs and enable `CONFIG_SPI_FLASH_HPM_ENA` first! - Flash 120 MHz SDR mode is stable. - Flash 120 MHz DDR mode is an experimental feature, it works when the temperature is stable. Risks: If your chip powers on at a certain temperature, then after the temperature increases or decreases by approximately 20 Celsius degrees (depending on the chip), the program will crash randomly. config ESPTOOLPY_FLASHFREQ_80M bool "80 MHz" config ESPTOOLPY_FLASHFREQ_40M bool "40 MHz" config ESPTOOLPY_FLASHFREQ_20M bool "20 MHz" endchoice
