Ov2640 module not working!!

[searchingforcode]

Hi i am using this module for testing https://www.aliexpress.com/item/OV2640-camera-module-Module-2-million-pixel-electronic-integrated-with-jpeg-compression-new-big-promotion/32915971973.html . It doesnt have XCLK pin on header as it says it already has an integrated 12mhz crystal. I have already succeeded with esp32-cam board (small camera one) with this firmware. But this ov2640 camera module not working. Its showing "Camera probe failed with error 0x20001". I think this code refers to connection issue. I have changed the wiring and pin configuration but still no change. My pin configuration is:

vsync-25
href-33
reset-23
d1-32
d3-12
d5-13
d7-21

scl-26
sda-27
d0-35
d2-34
d4-5
d6-18
plck-19
pwdn-gnd

Thanks. Waiting for replies.

Hello,
Have you found a solution for this ? I am facing the same error with the same module as you

Hi,
I'm having the same problem. Has anyone found a solution yet?

I'm having the same issue (ESP32-CAM with Ov2640), I know the module is working fine since I uploaded and used a demo Arduino sketch without any issues.

With ESP32_CAMERA_QR:

I (537) sccb: pin_sda 26 pin_scl 27
I (567) sccb: SCCB_Probe start
E (1827) camera: Camera probe failed with error 0x20001
E (1827) camera_qr_demo: Camera init failed with error 0x20001

I suppose there's a problem with twi (soft i2c) since reported camera ID is 0xff

edit: it's working now, I was trying the esp-idf 4.1 PR and for some reason it didn't work, with this 4.0 version I can actually decode QRCodes!

Hey guys,
So, I figured out a solution that worked well for my ESP WROVER.
Here is the configuration I used :)
