I flashed the esp32cam using the MB board but I get the following logs. The installation says its successfull but I get the following logs, which says otherwise

It looks like installing/uploading has gone OK, then the board shows this log once it tries to start up?

PSRAM chip not found or not supported suggests it can’t connect to the psram it’s been set to use.
I’d guess it’s either whatever’s being uploaded doesn’t exactly match the board/psram you’ve got, or there’s some kind of issue with the boards psram.

I haven’t used any of the esp32cams, but there may well be variations that need the board/psram defining differently?
What board do you have exactly, and what yaml are you uploading?

edit: this might help?

You haven’t uploaded your yaml.

4

Your board may not have PSRAM (strange, it should), or the chip is defectiverino.

You can still use it with a custom component I maintain (at limited resolutions, sadly):

Set setting framebuffer_in_psram to false in the esp32_camera settings. This turns off reliance on PSRAM.

5

Better yet: toss it and buy the Freenove cam. It’s much nicer and feels faster too.

I use it in my MK4 build;
