Hi,
What could be the reason for this error?
"usrp2: channel 0 not receiving
usrp2::rx_samples() failed"
>From some previously post, Johnathan said that this should be fixed in
>releases after 3.2.2
I'm using the latest git trunk version, I've change the firmware (to
txrx_raw_eth_20100608.bin) and the fpga image (to u2_rev3-20100603.bin) (I am
using USRP2 + RFX2400). And the error still occur! Why?
My top_block basically contains a usrp2_sink and a usrp2_source block and a
rx_path and a tx_path. The rx_path and the tx_path are changed during runtime
with the following sequence:
top_block.lock()
top_block.disconnect()
top_block.connect()
top_block.unlock()
The error occurs after a random number of switches of the different paths
(sometimes it works for 30 switches and sometimes just for 3) and the program
requires a restart to get rid of the problem.
Br,
Patrik Eliardsson
