mmlink¶
SYNOPSIS¶
mmlink [-B <bus>] [-D <device>] [-F <function>] [-S <socket>] [-P <TCP port>] [-I <IP Address>]
DESCRIPTION¶
Remote signaltap is software tool used for debugging the Accelerator Function Unit (AFU), effectively a signal trace capability that Quartus places into a green bitstream. Remote Signal Tap provides access the RST part of the Port MMIO space, and then runs the remote protocol on top.
OPTIONS¶
-B,--bus FPGA Bus number.
-D,--device FPGA Device number.
-F,--functio FPGA function number.
-S,--socket FPGA socket number.
-P,--port TCP port number.
-I,--ip IP address of FPGA system.
NOTES¶
Driver privilege:
Change AFU driver privilege to user.
$ chmod 777 /dev/intel-fpga-port.0
Change locked memory size:
edit the file /etc/security/limits.conf
$ sudo vi /etc/security/limits.conf
user hard memlock 10000
user soft memlock 10000
exit terminal and login new terminal.
verify that the locked memory is now set: ``` $ ulimit -l 10000
