* ***Note***: The files (BOOT.BIN, drivers, etc) in pre-built SD card img might not have the latest bug-fixes/features. Check related section in this README on how to generate them and update them if needed.
* ***Note***: If openwifi stops working after ~2 hours, it means the evaluation license of Xilinx Viterbi decoder has expired. You need to power cycle the board. Run this command several times on board to confirm:
root@analog:~/openwifi# ./sdrctl dev sdr0 get reg rx 20
SENDaddr: 00040050
reg val: 34be0123
(If the last number of reg val is always 3, that means the Viterbi decoder stops working)
