Are you sure that PSRAM is enabled? Could you please change the debug level to "Debug" and post the output of the boot console again?

Hello, can you please retest this on v2.0.3-rc1?

VojtechBartoska · 2022-05-03T13:56:23Z

any updates?

Hi, for me, with 2.0.4 still not work.

E (211) cam_hal: cam_dma_config(292): frame buffer malloc failed
E (212) cam_hal: cam_config(376): cam_dma_config failed

Camera init failed with error 0xffffffffCamera capture failed

Tested on two modules.

me-no-dev · 2022-05-09T08:41:15Z

The error suggests that you either have PSRAM not enabled or it is failing and does not function normally.

DmytroKorniienko · 2022-05-11T15:19:38Z

any updates?

Fixed for me in 2.0.3, thank you.

The same problem 2.0.3 can't be used, 1.0.6 is normal

Tony763 · 2022-05-18T06:38:56Z

Hello @youngda, do you have a PSRAM enabled? I use platform.io and project I wanted to build did not have it.

build_flags =
    -DBOARD_HAS_PSRAM
    -mfix-esp32-psram-cache-issue

With this, cam works again (2.0.4).

VojtechBartoska · 2022-05-18T09:27:43Z

folks, is this still valid?

rottifant · 2022-05-28T09:05:17Z

I got the same error with V2.0.3. (with Arduino IDE)
I enabled PSRAM and it works fine now.

Select the esp32 Dev development board, and try to open PSRAM in the configuration item. I still can't open it, but the upstairs said it can.

youngda · 2022-06-28T13:47:35Z

Hello @youngda, do you have a PSRAM enabled? I use platform.io and project I wanted to build did not have it.
build_flags =
    -DBOARD_HAS_PSRAM
    -mfix-esp32-psram-cache-issue
With this, cam works again (2.0.4).

Did not find 2.0.4, tested version 2.0.3, in arduino ide, opened PSRAM, and a new error appeared, I went back to 1.0.6 and it works normally.

It say the SPI SRAM memory test fail

Not a problem of frequency or upload speed. The problem is exactly what the error message says. Your psram is either not available, or is damaged. Note that psram requires 2 pins, and that usually includes gpio16, which is exposed on many devices.

So, do you think it's a good idea to change my FTDI Module?

these are my connections

Please Help me

Those having older ESP32 camera devices without PSRAM: make sure you set fb_location to CAMERA_FB_IN_DRAM
of camera_config_t, and fb_count to 1.
E.g. for M5Stack ESP32Cam:

camera_config_t esp32cam_config{
   .pin_pwdn = -1, 
   .pin_reset = 15,
   .pin_xclk = 27,
   .pin_sscb_sda = 25,
   .pin_sscb_scl = 23,
   .pin_d7 = 19,
   .pin_d6 = 36,
   .pin_d5 = 18,
   .pin_d4 = 39,
   .pin_d3 = 5,
   .pin_d2 = 34,
   .pin_d1 = 35,
   .pin_d0 = 17,
   .pin_vsync = 22,
   .pin_href = 26,
   .pin_pclk = 21,
   .xclk_freq_hz = 20000000,
   .ledc_timer = LEDC_TIMER_0,
   .ledc_channel = LEDC_CHANNEL_0,
   .pixel_format = PIXFORMAT_JPEG,
   .frame_size = FRAMESIZE_SVGA,
   .jpeg_quality = 12, 
   .fb_count = 1,       
   .fb_location = CAMERA_FB_IN_DRAM
};

E.g. for Micro-RTSP, edit src/OV2640.cpp

Hi folks, is this issue still valid or can be closed? Thanks

bigFin · 2023-08-22T16:58:44Z

@P-R-O-C-H-Y
I think so. I added the relevant build flags my branch of the ESP32-WROVER examples and will submit a pr on that side.

nhattran02 · 2024-08-16T03:03:53Z

Are you sure that PSRAM is enabled? Could you please change the debug level to "Debug" and post the output of the boot console again?

How about if my custom board does not support psram (ESP32S3 wroom 1 N16) ? Do you know if I can still use this camera library?

me-no-dev · 2024-08-16T07:07:04Z

Do you know if I can still use this camera library?

Only with JPEG and low resolutions
