Hi,
The reference clock for afe7950 is fed from lmx2694 directly and clock reate is 11520MHz.
I am trying to product constant test patten by using dacJesdConstantTestPatternValue function, but no signal.
I initialized afe by log file of Latte and jesd_fs_state value was read as 00, its expected value is 0x55.
1> When JESD RX states is not established, is not test pattern produced?
2> How can I check whether input reference clock is healthy or not?
There was no initial errors at early stage of test. The board seems to be worse as test goes on.
Anyhow 11520MHz clock from lmx2694 is recognized by spectrum analyzer.
3> the function dacJesdConstantTestPatternValue is a little bit different from Latte log.
When I select A, the registers Latte wrote are 0xb8 ~ 0xbb, but C function wrote 0xb8~0xbf.
4> Was the function checkDeviceHealth verified?
It looks like operating differently than comments.
5> C library verstion
I downloaded C_libraries_CAFE2p5.zip but zipped folder name was CAFE2p0. I need to check if I downloaded right file.
