PSRAM ERROR ..

[waldli]

Hello everyone,
I got 3 modules esp32-s3 R16N8 yesterday and wanted to install the latest

Annex32-S3 CAN USB DMT VGA HID 1.53.5 qio qspi LFS.
Flash Free: 13,623,296 RAM Free: 215,576

Everything works so far, but the PSRAM is not recognized.
I flashed all 3 modules with it because I thought the first one might be broken,
but all three showed the same error.
Then I tried with a different version and the PSRAM was recognized.

Annex32-S3 CAN DMT VGA 1.51.7 qio opi LFS
Flash Free: 13,623,296 RAM Free: 8,602,723.

Is there perhaps an error?

Here are the two versions as a log:

Hi,
maybe the difference is very "thin" but the versions you are mentioning are different :

Annex32-S3 CAN USB DMT VGA HID 1.53.5 qio qspi LFS.

and

Annex32-S3 CAN DMT VGA 1.51.7 qio opi LFS

The difference is the reason for which I publish several versions : the PSRAM can be QSPI (quad) or OPI (octal).

For your module you can simply flash the latest
Annex32-S3 CAN_DMT_VGA_HID_qio_opi_LFS 1.53.5
