VADC failed - i.MXSoloX

osmarfrisonjun1 — Mon, 22 Feb 2016 12:24:33 GMT

Hi,

I am trying to use the VADC at the MX6SX SDB. (i.MX L3.14.52_1.1.0 GA)

I connected the camera input at the VADC_IN0, and I checked the signal after the C353 using the oscilloscope, and it is okay.

The imx6sx-sdb.dts says:

&vadc {

vadc_in = <0>;

csi_id = <1>;

status = "okay";

port {

vadc_ep: endpoint {

remote-endpoint = <&csi2_ep>;

};

The i.MX_Linux_Reference_Manual says:

How can I test the camera input?

Answering my own question.

Using i.MX L3.14.52_1.1.0 GA

$ insmod /lib/modules/3.14.52-1.1.0_ga+g5f6f0a5/kernel/drivers/media/platform/mxc/subdev/mxc_vadc.ko

$ lsmod

Module Size Used by

mxc_vadc 6511 1

mx6s_capture 14549 0

ov5640_camera 20096 0

mxc_dcic 6569 0

evbug 1875 0

$ /unit_tests/mx6s_v4l2_capture.out -ow 720 -oh 576 -d /dev/video2 -t 50 -fr 30

it should work
