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?

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
E (212) camera: Camera config failed with error 0xffffffff

Tested on two modules.
The error suggests that you either have PSRAM not enabled or it is failing and does not function normally.
@VojtechBartoska @me-no-dev
any updates?
Fixed for me in 2.0.3, thank you.

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).

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.
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-issueWith 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.

@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: rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT) configsip: 0, SPIWP:0xee clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00 mode:DIO, clock div:1 load:0x3fff0030,len:1240 load:0x40078000,len:13012 load:0x40080400,len:3648 entry 0x400805f8 E (1875) spiram: SPI SRAM memory test fail. 131072/131072 writes failed, first @ 3F800000

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
@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.
