twi_sda = port:PE13<3><default><default><defaultHi @avaf,
I realize this is a pretty old thread, but I’m also struggling to get OV5640 working on the BPI M2 Zero (running the latest released Raspbian image), and I’ve been having the same error messagea in dmesg as @Flex when I connect the camera to it.
I’m using this particular camera, which should have the right pinout to the CSI connector on the BPI M2 Zero:
Inside of /boot/bananapi/bpi-m2z/linux/sys_config.fex, I see that twi2 is selected for csi0 (vip_dev0_twi_id = 2), and that twi2 is unused:
[twi0]
twi_used = 1
twi_scl = port:PA11<2><default><default><default>
twi_sda = port:PA12<2><default><default><default>
[twi1]
twi_used = 1

twi_sda = port:PA19<3><default><default><default>
[twi2]
twi_used = 0
twi_scl = port:PE12<3><default><default><default>
twi_sda = port:PE13<3><default><default><default>
Any help with this would be appreciated!
A quick glance at specification and I see two possible problems here, your sensor is MIPI and the pin layout is not reversed. You can search Armbian forum for OV5640, there you find a lengthy thread and lot of information about OV5640.
twi2 is not enabled because CSI interface will be used. MIPI is serial and CSI is parallel.
Купил родную камеру для banana pi zero. Подскажите как заставить ее работать. Именно, не получается установить драйвер. Система Armbian Ubuntu 18.04
Hello friends) I load ov5640 and sun6i_csi modules to /etc/modules of armbian hirsute_edge, restart, but my dmesg no speak about ov5640 or CSI.
root@bananapim2zero:~# dmesg |grep -i csi

How I can see whats happened or may be I can download image with ov5640 supported?
Hello, I’m also struggling with getting a camera module work on banana pi m2 zero.
So I have this module, which I think has reversed pins.
So I’ve got a reversed flat cable to make pin1 on the camera match pin1 on the board.
I’ve added a couple of modules on my /etc/modules
