ESP32-S3-PICO-1-N8R8 PSRAM not found - works on N8R2

[UnexpectedMaker]

Board

Internal development boards using both PICO-1-N8R2 and N8R8

Device Description

Trialing both S3-PICO-1 chips on my BLING! boards https://twitter.com/unexpectedmaker/status/1708986440208773258

Hardware Configuration

Lots of HW on the board, but not relevant to this issue.

Version

v2.0.14

IDE Name

Arduino IDE, PlatformIO

Operating System

MacOS

Flash frequency

80Mhz

PSRAM enabled

yes

Upload speed

1155200

Description

When initialising PSRAM psramInit() on the N8R2, it all works fine, but when I call that on the N8R8, I get the following error: psram: PSRAM ID read error: 0x00ffffff

I've checked this with 2.0.12 up to 2.0.14.

Sketch

Not specific to any sketch - happened when any code boots where PSRAM is enabled.

Debug Message

No debug message, no crash, just fails to initialise and use PSRAM.

Other Steps to Reproduce

No response

for R8 you need PSRAM=opi

for R8 you need PSRAM=opi

For the PICO-1-N8R8 ? I thought opi was for octal? This is not octal.

Oh wowza, holy moly!!!! Did not read that bit.... thanks mate !!! I'll go hide in my corner now and pretend this never happened.....

Rule of thumb: If it's not a custom job (like M5Core-S3) on ESP32-S3 8MB PSRAM is always OPI and 2MB is always QIO
