From 13bd67b4949a91df5e6696e708c935266b14c502 Mon Sep 17 00:00:00 2001 From: Josh Blum Date: Tue, 2 Mar 2010 14:48:11 -0800 Subject: The net common is too slow in usrp2 firmware to figure out if its vrt data. Added a custom function to tell if a packet is vrt data, seems to be feeding fast enough at this rate... Fixed some buffer size calculation logic. --- host/lib/usrp/usrp2/dsp_impl.cpp | 7 +------ 1 file changed, 1 insertion(+), 6 deletions(-) (limited to 'host/lib/usrp/usrp2/dsp_impl.cpp') diff --git a/host/lib/usrp/usrp2/dsp_impl.cpp b/host/lib/usrp/usrp2/dsp_impl.cpp index a57f5ff2d..8fdfd685f 100644 --- a/host/lib/usrp/usrp2/dsp_impl.cpp +++ b/host/lib/usrp/usrp2/dsp_impl.cpp @@ -82,12 +82,7 @@ void usrp2_impl::update_ddc_enabled(void){ out_data.data.streaming.enabled = (_ddc_enabled)? 1 : 0; out_data.data.streaming.secs = htonl(_ddc_stream_at.secs); out_data.data.streaming.ticks = htonl(_ddc_stream_at.ticks); - out_data.data.streaming.samples = htonl( - _mtu/sizeof(uint32_t) - - USRP2_HOST_RX_VRT_HEADER_WORDS32 - - USRP2_HOST_RX_VRT_TRAILER_WORDS32 - - ((2 + 14 + 20 + 8)/sizeof(uint32_t)) //size of headers (pad, eth, ip, udp) - ); + out_data.data.streaming.samples = htonl(_max_samples_per_packet); //send and recv usrp2_ctrl_data_t in_data = ctrl_send_and_recv(out_data); -- cgit v1.2.3
