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? |

any updates? |

Hi, for me, with 2.0.4 still not work. Tested on two modules. |
|
The error suggests that you either have PSRAM not enabled or it is failing and does not function normally. |
Fixed for me in 2.0.3, thank you. BTW: I reduced frame buffer from 16 to 8 frames for 2Mb frames, code part: |
|
The same problem 2.0.3 can't be used, 1.0.6 is normal |
|
Hello @youngda, do you have a PSRAM enabled? I use platform.io and project I wanted to build did not have it. With this, cam works again (2.0.4). |
|
folks, is this still valid? |
|
I got the same error with V2.0.3. (with Arduino IDE) |

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. |
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. ` Backtrace:0x400833c5:0x3ffb24800x4008d555:0x3ffb24a0 0x4009293d:0x3ffb24c0 0x40156e5e:0x3ffb2540 0x400d45af:0x3ffb25e0 0x400d464d:0x3ffb2800 0x400d62a9:0x3ffb2820 ELF file SHA256: 0000000000000000` |

@wecane Hi, I already changed the board for the one you mentioned, but the error persists, I'm beginning to think that they are problems of frequency or upload speed.
Attached image of my settings, please please, can someone help me? Now is this the new Error: E (2023) cam_hal: cam_dma_config(271): frame buffer malloc failed 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 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

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