I have a bring-up issue with my camera. I'm hoping someone else has experienced this issue and has a solution to the problem.
Description:
Details:
- user space code is based off of mxc_v4l2_capture application in imx-test
- camera initialization code has been provided by FAE
Has anyone seen this problem? At this point I don't know if this is a problem with the camera or the NXP hardware. I expect I may be able to resolve this using a reset in the NXP hardware. Any help would be greatly appreciated!
Hi SeanEdmnond, I am trying to use the OV9281 sensor with the imx8m SoC but I'm having some problems since there seems to be no available driver for this camera sensor... Do you have any driver code or suggestion that could help me? Thank you!
Best regards,
Alberto
Hi Sean
what is full processor name and error status values in MIPI_CSI_ERR
registers. One try to narrow down issue with rechecking clocks settings described
in sect.3.4. MIPI D-PHY clock AN5305 MIPI-CSI2 Peripheral on i.MX6 MPUs

I've seen the issue on 3 different NXP products:
i.MX6 Quad
i.MX6 Dual
i.MX6 Solo
I don't know the revision number, but I'll try to find it.
When the problem occurs, I usually see that the first value read on MIPI_CSI_ERR1 is non-zero. Every value after the first read is 0. The values that's I've seen are:
0x10 (error matching frame start with frame end)
0x1000000 (incorrect frame sequence)
0x1010 (CRC err, and error matching frame start with frame end)
I will double check the D-PHY clock settings. I was assumed this wasn't the issue because MIPI_CSI_ERR1[3:0] are all zero.
Hi Sean
what board used in the case, please try to test on nxp reference board i.MX6Q Sabre SD
with nxp bsps described on
Best regards
