I have made the mistake of designing a PCB where mostly io 6 but io 11 is used. Today I discovered that my code crashes for obvious reasons and after looking at the datasheet:
Does that "not recommended" mean I'm screwed or is there a way to utilize the pins?Pins CMD/IO11 and CLK/IO6 are used for connecting the embedded flash, and are not recommended for other uses.
If they can't be used would the connected GPS module (RX to io6, timepulse signal to io11) interfere with the flash and cause resets?
ps: Why aren't these embedded flash pins just marked with nc in the datasheet? There is no way to connect external psram so whats the purpose of breaking them out if people shouldn't use them?
Thanks for any information!
