Then it looks like the problem is actually in the next step, that is, loading the fpga bitstream /usr/local/hamradio/gnuradio/share/usrp/rev4/std_2rxhb_2tx.rbf So I have 3 questions: 1. What can I use to trace/debug/investigate the final fpga load operation? 2. Where is the source code of the program performing the actual fpga load? 3. What does it mean that led D402 turns on during this? t. i.a. for help Alberto Attiva Tiscali Voce 8 Mega: telefoni e navighi senza limiti a soli €15 AL MESE PER 1 ANNO. Dopo paghi €29,90 al mese.
