more and more confusing now
Wrover Starter Kit says:
-> GPIO16 and GPIO17 are used as the CS and clock signal for PSRAM. To ensure
reliable performance, the two GPIOs are not led out.
GPIO16 = CS
GPIO17 = CLK
but we read now in the future/pSRAM_maloc
To connect the ESP-PSRAM chip to the ESP32, connect the following signals:
- PSRAM /CE (pin 1) - ESP32 GPIO 17
PSRAM SO (pin 2) - flash DO
PSRAM SIO (pin 3) - flash WP
PSRAM SI (pin 5) - flash DI
PSRAM SCLK (pin 6) - ESP32 GPIO 16
PSRAM Vcc (pin 8) - ESP32 VCC_SDIO
thanks - please.
and yes, if you see here in the pSRAM code ...

the pins swapped to the describtion
which part is the right part now`?
