Hi ,

I'm trying to port a 4-lane Bayer raw camera to i.MX6Q. But the image doesn't come.


After checking the MIPI_CSI register,

the MIPI_CSI_PHY_STATE is fine, the bit 7:4 switched between 0xF and 0x0,

and the MIPI_CSI_ERR1 is very weird, because it returns 0x10000010, as I know, bit 4 is indicating the FS/FE error of virtual channel 0. But I connected the camera to IPU0_CSI1 according to AN5305, this channel only accept virtual channel 1, and sensor was configured in virtual channel 1. But some unimportant information data from sensor does use virtual channel 0, I don't want handle them for now. 


The question is, does the bit 4 (err_f_bndry_match_vc0) and bit 28 (err_ecc_double) matters in my case? Could I ignore the bit 4?


If not, which part should I check?
