Issue or Suggestion Description

Hi all,
I found your project and I had the idea to use it for my debugging stuff.
Finally I managed it to build it with the described steps.
But after upload I see the message at the UART Log, with no available PSRAM, but if I check the SPIRAM I get the info that 8MB are available.
I have a ESP32-S3 N16R8.

Unfortunately I won't see a SSID for the WiFi and I do not really know if the device is working propperly.

Could you help me a littl bit with that.

Many thanx in advance and
BR
Michael

You may need check the Support for external SPI-connected RAM in menuconfig

[Minimik]

Ok, I already did that. There are some additional params under that point which may be configured too.

Is there any example how I shall configure the build.

[solosky]

I am not the expert of ESP32, you may try to read the help text to understand whether changes required for additional params.
But first, I think you could give a try to enable the SPI PSRAM first, leave other addition params unchanged and test if it works or not.

Hi again,
I checked the ESP PSRAM and I think I checked this section. I think
[*] Support for external, SPI-connected RAM
means that?!? :)

At the startup I receive between others the following lines

...
10:16:33.822 -> I (629) boot: Disabling RNG early entropy source... 10:16:33.858 -> E (639) quad_psram: PSRAM ID read error: 0x00ffffff, PSRAM chip not found or not supported, or wrong PSRAM line mode 10:16:33.858 -> E cpu_start: Failed to init external RAM, needed for external .bss segment
...

Is there somewhere a working configuration for the ES32S3 ( ESP32-S3-WROOM-1)?
At the moment I do not have any idea what to do to get it initially running.

Many thanx

Could you select octal mode an try again?

Now, I'm a step further, and I get the Application starting and I see the Webpage when I connect to it.
I had to change the RAM clock speed (default was 80 MHz):

Component config > ESP PSRAM > Support for external, SPI-connected RAM > SPI RAM config > Set RAM clock speed (40Mhz clock speed) > 40Mhz clock speed
