Hi All...

I want to make sure I read the ESP32 data sheet correctly. Did it say that it can have up to four external flash chips, but none can be bigger than 16 Megabytes?

No, the 16mb limit only applies to the cache.

Oh that's great thank you. I just ordered some Winbond 1Gb SPI chips to test with.

Hi,

how did the test with the 1 Mega Bit Winbond chip go?
