i tried using that command but it returned this :

Code:

a@raspberrypi:~ $ gpioset --mode=wait $(gpiofind CAM_GPIO)=1 &[1] 1586 gpioset: error setting the GPIO line values: Device or resource busy
i also tried using "sudo dmesg | grep -i i2c" and i got this on the IO board that the camera work on :

Code:

@raspberrypi:~ $ sudo dmesg | grep -i i2c[    0.057996] /soc/csi@7e800000: Fixed dependency cycle(s) with /soc/i2c0mux/i2c@0/imx500@1a[    0.058025] /soc/csi@7e801000: Fixed dependency cycle(s) with /soc/i2c0mux/i2c@1/imx500@1a[    0.058122] /soc/i2c0mux/i2c@0/imx500@1a: Fixed dependency cycle(s) with /soc/csi@7e800000[    0.058149] /soc/i2c0mux/i2c@1/imx500@1a: Fixed dependency cycle(s) with /soc/csi@7e801000[    0.059258] /soc/csi@7e800000: Fixed dependency cycle(s) with /soc/i2c0mux/i2c@0/imx500@1a[    0.059376] /soc/csi@7e801000: Fixed dependency cycle(s) with /soc/i2c0mux/i2c@1/imx500@1a[    0.076839] /soc/i2c0mux/i2c@0/imx500@1a: Fixed dependency cycle(s) with /soc/csi@7e800000[    0.076889] /soc/i2c0mux/i2c@1/imx500@1a: Fixed dependency cycle(s) with /soc/csi@7e801000[    1.917976] i2c_dev: i2c /dev entries driver[    2.850211] brcmstb-i2c fef04500.i2c:  @97500hz registered in polling mode[    2.850780] brcmstb-i2c fef09500.i2c:  @97500hz registered in polling mode[    2.896127] /soc/csi@7e800000: Fixed dependency cycle(s) with /soc/i2c0mux/i2c@0/imx500@1a[    2.896200] /soc/i2c0mux/i2c@0/imx500@1a: Fixed dependency cycle(s) with /soc/csi@7e800000[    2.896428] i2c i2c-22: Added multiplexed i2c bus 0[    2.898720] /soc/csi@7e801000: Fixed dependency cycle(s) with /soc/i2c0mux/i2c@1/imx500@1a[    2.898789] /soc/i2c0mux/i2c@1/imx500@1a: Fixed dependency cycle(s) with /soc/csi@7e801000[    2.899047] i2c i2c-22: Added multiplexed i2c bus 10[   14.812815] i2c 0-001a: deferred probe pending: i2c: supplier clocks:clk-aicam-gated0 not ready $
And this on my PCB where the camera is not working:

Code:

@raspberrypi:~ $ sudo dmesg | grep -i i2c[    0.058155] /soc/csi@7e800000: Fixed dependency cycle(s) with /soc/i2c0mux/i2c@0/imx500@1a[    0.058185] /soc/csi@7e801000: Fixed dependency cycle(s) with /soc/i2c0mux/i2c@1/imx500@1a[    0.058281] /soc/i2c0mux/i2c@0/imx500@1a: Fixed dependency cycle(s) with /soc/csi@7e800000[    0.058308] /soc/i2c0mux/i2c@1/imx500@1a: Fixed dependency cycle(s) with /soc/csi@7e801000[    0.059412] /soc/csi@7e800000: Fixed dependency cycle(s) with /soc/i2c0mux/i2c@0/imx500@1a[    0.059529] /soc/csi@7e801000: Fixed dependency cycle(s) with /soc/i2c0mux/i2c@1/imx500@1a[    0.076832] /soc/i2c0mux/i2c@0/imx500@1a: Fixed dependency cycle(s) with /soc/csi@7e800000[    0.076882] /soc/i2c0mux/i2c@1/imx500@1a: Fixed dependency cycle(s) with /soc/csi@7e801000[    2.173865] i2c_dev: i2c /dev entries driver[    2.973521] brcmstb-i2c fef04500.i2c:  @97500hz registered in polling mode[    2.979180] brcmstb-i2c fef09500.i2c:  @97500hz registered in polling mode[    3.093206] /soc/csi@7e800000: Fixed dependency cycle(s) with /soc/i2c0mux/i2c@0/imx500@1a[    3.093287] /soc/i2c0mux/i2c@0/imx500@1a: Fixed dependency cycle(s) with /soc/csi@7e800000[    3.093526] i2c i2c-22: Added multiplexed i2c bus 0[    3.101543] /soc/csi@7e801000: Fixed dependency cycle(s) with /soc/i2c0mux/i2c@1/imx500@1a[    3.101617] /soc/i2c0mux/i2c@1/imx500@1a: Fixed dependency cycle(s) with /soc/csi@7e801000[    3.101857] i2c i2c-22: Added multiplexed i2c bus 10[   14.812804] i2c 0-001a: deferred probe pending: i2c: supplier clocks:clk-aicam-gated0 not ready[   14.812808] i2c 10-001a: deferred probe pending: i2c: supplier clocks:clk-aicam-gated1 not ready
I noticed that this "deferred probe pending: i2c: supplier clocks:clk-aicam-gated1 not ready" is returned on both I2C 0 and I2C 10 on my PCB but only returned on I2C 0 on the io board, i don't know if it can help figure out the problem.
