a try to get the clock signal from a custom mipi camera board on a sabrelite board. And i have found several code for PLL clock from :
this two message give two different value for a PLL at 999MHz : 0x74 and 0x3a
I try both but for each i have the PHY_STATUS 2f0
What is the good value ?
Ok i found the problem :
The camera was started before the init of my module. So i change it and i set the register value 0x3a ( for 999MHz) and i received the statut 3F0 for 4 lane.
I think all is ok. Now i must be check the clock setting hsp_clk and pixel_clk.
I had trying all register value between 0x00 and 0xFF for the PLL clock (mipi_csi2_write(info, 0x000000XY, CSI2_PHY_TST_CTRL1);) and for each i receive several 0x200 and finally the PHY_STATE 0x2f0.
I think i have an error in my driver. Perhaps i forgot to enable something.
The clock signal was checked in the mipi before imx6 : all is ok.
Anybody have an idea on what can be the problem ?
Thank you for posting your findings! I'm sure they'll help other community users!
