hi,
1. i have connected the 953/954 eval kit together with the 2Mp camera kit that comes with the 953/954 eval kit. After connection and initiailization using the proper script, the image format seen from 954 side is : 1920bytes by 1080 lines. Qn : is the data sent by this image sensor set at RGB888 ? that means 1 byte/pixel ? thus 1920 pixels means 1920 bytes ?
2. for the test pattern sent by 953 or 954, with 953 connected to 954 using coax in synchronous mode. ref clk from 954 is 24MHz. Link : pass, locked.
a. if the test pattern is activated by 954 side, then the test pattern image is seen by host processor - this checks the link from 954 to host processor, correct ?
b. if the test pattern is activated by 953 side, then the test pattern is serialized and transmitted to 954 and the image is seen by host processor - this checks the link from 953 to 954 to host processor, correct ?
c. what should the test pattern look like ? are they grey scale bars ? the setting for color is of values : 00 to FF. pls see below image, i am getting pinkish test pattern bars.
d. is the test pattern sent in RGB888 format ?
3. Now i proceed to connect my sensor to 953 and connected to 954 by coax cable, PoC, ref clk at 954 is 24MHz, in synchronous mode. When the sensor is set to send 1920x1080, at 954 side, the following image size is read :
2989 bytes by 1103 lines when it is supposed to be 1920x1080 format.
2989/1920 = 1.556, it should be 1.5 if the sensor is sending 12bits format.
1103/1080 = 1.02, it should be 1
can i check if the sensor is sending 12 bits or 10 bits format, how does the 953/954 serdes ics package the data stream, is there any particular format the data stream is converted to after going thru 953/954 ?
When the sensor is just connected to the host processor directly, when set to 1920x1080 format, a proper image can be seen. But when connected thru the 953/954 serdes, after receiving the image from 954, the image is distorted. pls see attached picture.
Appreciate any advise on what may be wrong here. Many thanks.
