Hi:
When board reboot, driver tried to reset camera, there is error:
kernel version is v2.6.26-ti-07252008. Does anyone see it before?

Quoted 4 lines

console [ttyS2] enabled
brd: module loaded
loop: module loaded
eth0: LAN9211 (rev 0) at 0xc8908000 IRQ 312

Quoted 8 lines

eth0: Ethernet addr: 00:08:ee:02:53:22
eth0: LAN911x Internal PHY
Linux video capture interface: v2.00
omap24xxvout: registered device video1 [v4l2]
omap24xxvout: registered device video2 [v4l2] Clock cam_ick didn't enable in 100000 tries Clock cam_mclk didn't enable in 100000 tries isp_af_init

I have tried to open /dev/video/0, but there is no such device. and I add some debug info in isp_get call, and found that content of register cm_fclken_cam is 03, and content of cm_icklen_cam is 0,but cm_idlest_cam is 0x1, so clk init failed. For the kernel option I have choiced:

even there is some clk error report, but isp_get return successfully.
1. why there is no such device?
2. do you know the sensor name of sensor module? and datasheet?
3. what's the interface used by ldp board to connect sensor? serial or parallel port?

Any suggestion will be appreciated.
