A: By the RT (i.e. realtime) log we mean the messages generated by the
|
|
|
LM32 CPU inside the Virtex FPGA. They may provide useful information for
|
|
|
debugging the timing subsystem. They can be viewed by connecting a
|
|
|
serial terminal to the the front left USB port (up to v. 3.2 switches)
|
|
|
or the "FPGA test" USB port in the rear (newer switches). RS232
|
|
|
parameters are 115200, 8N1.
