Greetings!
We are currently developing a DTV receiver that will run on Linux based on the Silabs chip and Cypress fx2lp USB chip. However, we are facing a problem with the shared library "libCypress.so". The problem is whenever we try to turn on the GPIF to stream TS packets to UDP via USB the library is causing a segfault error every time.
OUR SETUP:
Ubuntu 18.04 kernel 5.4.0-48-generic
Below is the gdb result when running under it. Thank you in advance.
Solved! Go to Solution.

Hello,
Can you please contact the library provider? We need to know how the Cypress APIs are being implemented in the library you are using and which API is actually the cause for error to debug the issue.
Thanks,

Hello,
Can you please let me know which API from the Cypress linux Library, libcyusb was used?
Also can you please attach a snippet from the linux host application where the API was called?
Thanks,
Yatheesh

Hello,
We are using the CyAPIUser.h provided by Silabs with a shared library called "libCypressUSB.so". To my knowledge, there is also an equivalent library for windows (CypressUSB.dll and CypressUSB.lib), and the windows version works fine, but the linux equivalent doesn't.
Thanks.

Hi,
We already have communicated with the provider, however, they can't say much about the shared library. They advised us to directly contact the cypress team. Would it be possible for me to send an email directly to you so that I could give you the CypressAPI.h and the libCypressUSB.so provided by the DVB chip manufacturer?
Thank you.
