ESP32-C3FN4 GPIO17

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!

GPIO17 is SPIQ, so no, the flash is attached to that and as such it's not usable.
