Hi,Can CX3 support 4K raw10 @30fps resolution? or 4K raw8 @30fps ?
If CyU3PMipicsiReset() is initialized before CyU3PMipicsiInit (), it will report the error CyU3PMipicsiReset Err = 0x44, and then the initialization succeeds after CyU3PMipicsiInit ().
But now cx3 DMA cannot receive mipi data, and the mipi end can be measured with data,Why can't you receive data?
thank !

1. 0x44 comes when we reset the MIPI without initializing it. Refer 5.25.6.11 CyU3PReturnStatus_t CyU3PMipicsiReset ( CyU3PMipicsiReset_t resetType ) in API Guide.
2 CX3 can supports at maximum 2.4 Gbps.
MIPI block on CX3 supports up to four data lanes
Each lane supports up to 1 Gbps
Note: CYUSB3065 supports up to four lanes; CYUSB3064 supports up to two lanes
3. As per your requirement:
1. 4K RAW 10 30fps = (3840+Horizontal Blanking) * (2160+ Vertical Blanking) * 10 * 30 = 2.488 Gbps > 2.4 Gbps ( Assume blanking is Zero. Ideally there should be blanking period) - CX3 Does Not Support
2. 4K RAW 8 30 fps = (3840+Horizontal Blanking) * (2160+Vertical Blanking) * 8 * 30 = 1.99 Gbps < 2.4 Gbps (Assume blanking is Zero. Ideally there should be blanking period) - CX3 Supports
4. What is the MIPI configuration that you are using in this case, what is the frame rate, resolution, frames per second and bits per pixel?

Dear Srdr,
Although the payload 3840*2160*30 *8 is less than 2.4Gbps, but I cannot configure CX3 successfully.
I know CX3 embed a tc358746 from Toshiba in chip, I get an XLS tool from Toshiba and use it configure 3840*2160*30fps*8bit(raw8).
It seems the max fps is about 11, so can you share how to configure 4K raw8 image sensor ,eg, sony IMX135?
