Hi, I'm trying to get the CX3 to work with a csi-2 bridge (toshiba TC358746AXBG). I'm starting with the ez-usb image sensor configuration tool and then i enter the bridge parameters.
Here are the parameter i measured on a scope.
And here are the result that i have. The state machine value is always 0x2 and i got no error from CyU3PMipicsiGetErrors(). I also used CyU3PMipicsiSetPhyTimeDelay(1,0x0B) to set a delay as suggested by the CX3 MIPI interface.
Does it need something else to work ? also, the value i measured on the scope. I also already tried to test if it work in continuous clock mode.
h-active = 30us
h-blank = 6.8 us
V-active = 24.8ms
v-blank = 8.48ms
Thank you for your help
Ps, when i edit some of the parameter ex. h-blank, hs-prepare... nothing change in h and c files. does the compiler directly use the cycx file ?

Hi,
- If the state is stuck at 0x02, then CX3 is not seeing Frame start. (You can confirm this by probing the FV and LV test pins on CX3 - these pins might not show any activity).
- Can you try different values of Phy time delay around 11.
- Can you make sure that the mipi data coming to CX3 data lanes is good?
Regards,
Hemanth
