ESP32-C3FN4 GPIO17
Posted: Fri Mar 03, 2023 7:05 pm
Hello hello,
Im wondering if i understood right, internal Flash is using following:
3 Ports of embedded flash correspond to pins of ESP32-C3FN4 and ESP32-C3FH4 as follows:
• CS# = SPICS0
• IO0/DI = SPID
• IO1/DO = SPIQ
• CLK = SPICLK
• IO2/WP# = SPIWP
• IO3/HOLD# = SPIHD
However im wondering how can i use GPIO17 as GPIO? I tried PIN_FUNC_SELECT(IO_MUX_GPIO17_REG, FUNC_SPIQ_GPIO17); but it would cause constant reboot TG1WDT_SYS_RST.
Thanks!
