UPP EOL interrupt missing

$

Hi,

I have been debugging a Linux UPP driver for L138. The UPP is connected to FPGA for receiving data purpose. My configuration is:

--------------------------

Receive mod with single channel ,

Byte Count = 31KB   //

It seems the value cannot exceed 32KB, otherwise can only receive data in first line, no data for the rest of lines

Line Count = 64

Line Offset = 31KB

---------------------------

The problem is when I sent 1MB data to UPP, I can only get 6 EOLs. But I can see that all 1MB data is correctly written into memory. Can somebody figure out why?
