A call to read_raw( ) eventually flows execution to within the method called def katcprequest( ) located in the following file, (236)
https://github.com/casper-astro/casperfpga/blob/master/src/transport_katcp.py Therein, self.blocking_request() is called at 261. The returned 'reply' raises the exception on line 266. - File "/home/xpswhite/cfpga/casper_venv/lib/python3.8/site-packages/casperfpga-0.4.4.dev1336+py38.276ee44-py3.8-linux-x86_64.egg/casperfpga/transport_katcp.py", line 297, in katcprequest - raise KatcpRequestFail( - casperfpga.transport_katcp.KatcpRequestFail: Request write on host xxx.177.143.xxx failed. - Request: ?write counted_capt_buffer_ctrl 0 \0\0\0\0 - Reply: !write fail I am currently using a tcpborphserver3 listening on port 7130.

The client is able to connect just fine to port 7130, but these reads and writes to software registers fail in the following way shown above. The content of the request "looks" to be just fine. During reads, it actually returns the number 4 in the reply, which is correct. So something else is populating errors in re A possible fix here is to inform the blocking_request() call with the new port I am using. Is there a way to inform this call with the particular port? Another possible fix is that port 7130 must be let through a firewall on the SoC board.
