Environment Variables
Some behaviours can be controlled through environment variables.
DEBUG_FPGA
To override the configured attribute/method discovery settings and expose everything,
set DEBUG_FPGA
to 1
, true
, yes
, or on
(case insensitive).
FPGA_POST_FW_LOAD_DELAY
Inserts a small delay after loading firmware & creating memory buffers, before checking the “magic number” register. This is experimental, to see if it helps with occasional errors. Supply a numeric value (e.g. “0.05”), in seconds. Defaults to 0.
FPGA_XRT_TIMEOUT
Milliseconds allowed per FPGA ARGS register transaction. Supply an integer value. Defaults to 5.
