Hi all,
I'm trying capture images from an ov5640 sensor on parallel mode. The
sensor output format is UYVY8_2X8.
And the CCDC input is configured as UYVY8_2X8 too. I can do it, after
I applied the Laurent's patches:
"[PATCH 0/6] YUV input support for the OMAP3 ISP".
I have my sensor configured:
{
.subdevs = cm-t35_ov5640_primary_subdevs,
.interface = ISP_INTERFACE_PARALLEL,
.bus = {
.parallel = {
.data_lane_shift = 2,
.clk_pol = 0,
.hs_pol = 1,
.vs_pol = 1,
.data_pol = 1,
},
},
I defined ISP_ISR_DEBUG and DEBUG in the isp.c
Then, I configure the media-controller pipeline and try to capture:
media-ctl -v -r -l '"ov5640 3-003c":0->"OMAP3 ISP CCDC":0[1]'
media-ctl -v -l '"OMAP3 ISP CCDC":1->"OMAP3 ISP CCDC output":0[1]'
media-ctl -v -V '"ov5640 3-003c":0 [UYVY2X8 640x480]'
media-ctl -v -V '"OMAP3 ISP CCDC":0 [UYVY2X8 640x480]'
yavta -f UYVY -s 640x480 --capture=5 --file=image# /dev/video2
In this point, it hangs, and I need hit ctrol-c.
I get this message:
[ 1640.308807] omap3isp omap3isp: CCDC stop timeout!
I have observed that I don't get any interrupt messages. However, the
DATA0:7, PCLK, HSYNC and VSYNC is working fine, I guess.
NOTE: the sensor has externel 24 MHz oscillator, and the signals never
stop into CCDC:
Somebody can help me?
Thanks
Regards
Adriano Martins
