RK3288 ov13850_v4l2-i2c-subdev #32

Closed teseo-sw closed 7 years ago

teseo-sw commented 7 years ago

Hi, I am trying to capture stream of a ov13850 mipi camera. I am able to communicate with sensor via i2c but stream always hang on VIDEOC_DQBUF. Is kernel MIPI infrastructure complete and working or something is under development yet? I have tried both MMAP and ION but nothing changes.

Searching online I have seen this thread and I suppose kernel CIF_ISP camera driver is not complete yet. Is it so?

Could you give me some advice? thank you for the attention, best regards Andrea

There is a new standard ISP driver are developing, it will takes some months to finish it.

You can get the early access one from my github for fun or study https://github.com/wzyy2/linux/tree/tmp/cam

Hi Jacob, so, with the current CIF_ISP driver is not possible to transfer any frame data successfully? Following wiki at http://rockchip.wikidot.com/mipicsi I suppose someone already have used this ISP driver to get sensor data using ION. Is this not so?

thank you, regards Andrea

There might be some bug in driver, i don't know. It work in rk3288 years ago...

wzyy2 commented 7 years ago

Anyway, we won't have any develop plan or bug fix in this drvier in rk3288.

I have push the new MIPI CSI driver to isp-early-access branch. https://github.com/rockchip-linux/kernel/tree/isp-early-access

I will maintain this branch until it be merged into release-4.4. Report bugs are welcome.

Missing feature in this new driver:

@wzyy2 Hi, has the new driver supported MIPI-TXRX port yet?

zhujiongfu commented 7 years ago

According to mipi_dphy_sy.c file, it hasn't configed any register about txrx port yet, which means new driver doesn't support txrx port? Is that right?
