I tried running a code that uses the PSRAM, but I got the following error:

E (164) psram: PSRAM ID read error: 0x00ffffff

I changed the memory_type of the seeed_xiao_esp32s3.json definition file to qio_opi and then the PSRAM issue is fixed.

This PR intends to fix this problem.

Hi @alwint3r, thanks for the PR. For some reason PSRAM is disabled in the Arduino core. Is it wrong there?

It is wrong in Arduino too. The used module has OPI flash.

Hi, @valeros and @Jason2866. The PSRAM is disabled by default if you are using Arduino IDE. It can be enabled by choosing the OPI PSRAM option. So, I don't think it's wrong. Maybe people from Seeed Studio decided that the PSRAM is disabled by default for Arduino IDE users.
