Cannot capture video or image for SBGGR12_1X12 format with Pico DCAM20 Camera Module

Hi,

Currenty I am working on i.MX8M Nano with Camera module Pico DCAM20 (2 lanes). To add support for this driver, I added the driver file addi903x.c as attachment.

Mark , the addi903x need 2 lanes 135Mhz mipi clk RAW12bit 

In our Linux 5.4.3 MIPI driver added support for MEDIA_BUS_FMT_SBGGR12_1X12 like this:

Anything I missed or configured wrong? Can somebody give me some advice? 

Should I modify the mipi csi clk in the i.mx8mn.dtsi file? 

Why it hang ? 

Thanks & Best Regards,

Michael

Hi weidong.sun

Many thanks for your continuouns support .

As I know , I.MX8M nano can not support the virtual channel , we have just set  csi_id = <0> in the device tree ,is this mean the channel your mentioned .

We can read more register value ,and follow the i.mx8m nano reference manual to find out any incorrect setting .But we have no any detail information APN about the MIPI CSI setting .  

In mearn while , can you point out what are the key register we should check.

Hi King,

>>csi_id=0, OK

>>MIPI_CSI_INTERRUPT_SOURCE_0 register

dump the value of register, you will have to change source code to get the value, because memtool can't access it.

>>About MIPI signals

After the MIPI signal is amplified, check whether there is a short packet in the data.

【注】Here let me write it in Chinese.

现在面临的问题是,CPU收到的数据包中,没有帧头和帧尾,那么数据会被丢弃。因此可以看到有数据进来,但是没有被处理。

Hi weidong.sun

So what can I do it? 000000F0 mean the I.MX8 can not detect any mipi data signal ? But we can measure the mipi data signal with the oscilloscope.微信图片_20200720153001.jpg

0x32E30020: 000000C0, mean data is received.

so expert suggests you can read more registers' value, and check them.

From registers' value you got,  on CPU side, no Frame Start and Line Start were found.

so you can check if Virtual Channel is set to 0 in camera driver.

Hi Wigros,

 I compared DCAM20 and OV5640, ISI CSC is bypassed in DCAM20 but not in OV5640 and   current virtual channel both are 0.

Regieter values are listed as below

See below, please!

-------------------------

Since register MIPI_CSI_DPHY_STATUS (0x32E30020), keeps value "000000F1", please make sure Camera module Pico DCAM20 had output MIPI CSI2 signals correctly.

-------------------------

Have  a nice day!

Hi King,

See feedback from expert team:

--------------------------------------

0x32E30020 is changed from "000000F1" to "000000F0", clock lane is not in stop state now, but all data lanes are still in STOP state.

Have a nice day!

Hello king Liu,

Below is feedback from i.MX Expert team:

-----------------------------

Please dump ISI and MIPI CSI2 registers after run capture command.

The customer run capture command with "&" in background, then use memtool to dump the registers.

-----------------------------

Have a  nice day!
