[Question]<PSRAM ID read error>

[liqijian101]

The chip I use is esp32-s3-wroom-1 n4r8. When I turn on PSRAM, the prompt error is "E (205) psram: PSRAM ID read error: 0x00ffffff" . And now I can only use USB to download programs. I can't use UART0. UART0 doesn't respond. Luc, do you have any solutions? I look forward to your reply

Does your board has PSRAM ? does this sketch is working ?

#include <Arduino.h>

void setup() {
  log_d("Total heap: %d", ESP.getHeapSize());
  log_d("Free heap: %d", ESP.getFreeHeap());
  log_d("Total PSRAM: %d", ESP.getPsramSize());
  log_d("Free PSRAM: %d", ESP.getFreePsram());
}

void loop() {}

About UART0 what do you mean ? the device does not answer when flashing ? what the error ? this is not clear

[liqijian101]

that sketch can not work, it has the same error. My board did have PSRAM.

[luc-github]

It means the PSRAM is not detected - for that ESP3D cannot do anything Check if pins are correct for S3 as pinout change a lot https://docs.espressif.com/projects/esp-idf/en/latest/esp32s3/api-guides/external-ram.html

I suggest to raise question on ESP32 discord or gitter they may have some clue - as I does not have suche device and so never encounter the issue

[liqijian101]

I found the cause of the problem. Because the PSRAM on the chip I'm using is the OCTAL SPI, not the Quad SPI. I set up OPI PSRAM in the Arduino ide and it works. But how do I set this in platform io

[luc-github]

it seems it is dout when I flash with OPI it do --flash_mode dout but it is not enough I think I see:

esp32s3.menu.PSRAM.disabled=Disabled
esp32s3.menu.PSRAM.disabled.build.defines=
esp32s3.menu.PSRAM.disabled.build.psram_type=qspi
esp32s3.menu.PSRAM.enabled=QSPI PSRAM
esp32s3.menu.PSRAM.enabled.build.defines=-DBOARD_HAS_PSRAM
esp32s3.menu.PSRAM.enabled.build.psram_type=qspi
esp32s3.menu.PSRAM.`=OPI PSRAM
esp32s3.menu.PSRAM.opi.build.defines=-DBOARD_HAS_PSRAM
esp32s3.menu.PSRAM.opi.build.psram_type=opi

and also

esp32s3.menu.FlashMode.opi=OPI 80MHz
esp32s3.menu.FlashMode.opi.build.flash_mode=dout
esp32s3.menu.FlashMode.opi.build.boot=opi
esp32s3.menu.FlashMode.opi.build.boot_freq=80m
esp32s3.menu.FlashMode.opi.build.flash_freq=80m
esp32s3.menu.FlashMode.opi.build.flash_type=opi

Which arduino settings are working with your PSRAM ? can you share all ?

I found this https://community.platformio.org/t/how-development-esp32-s3-wroom-2/28232/3 I am not sure it is necessary to recreate a json or just added them manually and which values are necessary at least this one should be necessary board_build.arduino.memory_type = opi_opi

[luc-github]

have look to this issue too : https://github.com/espressif/arduino-esp32/issues/6646

Sorry I cannot help more as I do not have hw to test

[luc-github]

does it help ?

[liqijian101]

I tried that board_build.memory_type = qspi_opi or board_build.memory_type = opi_opi . but it also has errors.

[luc-github]

you must add arduino as json has it board_build.arduino.memory_type = opi_opi

[liqijian101]

it works. thanks very much.

board_build.arduino.memory_type = qspi_opi

[luc-github]

cool

Does the cam works with ESP3D now ?

[liqijian101]

not works. I have checked the pin of camera and it is correct. But there are no images on webui

[luc-github]

did you try https://github.com/espressif/arduino-esp32/tree/master/libraries/ESP32/examples/Camera/CameraWebServer ?

[liqijian101]

it can not work.Maybe there's something wrong with my board. I'll keep checking

[liqijian101]

HI Luc. my board can work. It is a circuit welding problem. thaks for your help.

[luc-github]

恭喜恭喜
