Hi I try to cnifgure for my board the external psram 8MB of my wrrom n16r8 but even if the ram if detected, there is a config issue:

As i have 8MB here, i selected Octal Mode, and it select by default pin30 and 26 for sck and cs, pin that are normally used on my pcb, but i removed the component to be sure for the test.

But as the help mention that it is possible to use any unused gpio, I changed to gpio41 and 42 that are left open, but it seems that range in kconfig for this value are 0-33, so in sdkconfig, my modifications seems to not be effective, and i still see the 30 and 26 value:

How to you do for this wroom kit please ?

Thank you

Are you trying to change the wiring of the PSRAM on the N16R8 module via software?!
