Point taken. - I didn’t actually check the original default values of the VID and PID, but they were reset according to the table provided, so that they could be tested as arguments in the make statement below. “About the Motherboard and Daughtercard EEPROM on USRP Devices (5th August 2020)”
The aim is to be able to manipulate some GPIO bits in the block work function and to align events using the 1PPS input. Regards, David GD4FMB From: Marcus D.

It contains some useful code, but I have not compiled and run it. Other example code in “Synchronising USRP Events using Timed Commands (17 April 2020)” has been used in the OOT block. 1) I have configured my B210(NI) EEPROM with the correct USB vid = 0x2500 and pid = 0x0814. The device is clearly identifiable and usable over USB3. 2). I have tried to identify the USRP using the following code prior to making an object:- uhd:: device_addr_t hint; hint[“serial”] = “3150322”; uhd:: device_addrs_t dev_addrs = uhd:: device::find(hint); 3). Or the following to create the object directly:- uhd::usrp::multi_usrp:: sptr device = uhd::usrp::multi_usrp::make(“vid=0x2500, pid=0x7814”); The codes are placed in the OOT constructor, compile and link with the appropriate headers. In both cases the flow-graph fails to run with the usual ‘block’ attribute error message. There are no USRP source or sink blocks in the flow-graph that could possibly conflict. Regards, David COuld you just use one of the standard test tools like "rx_samples_to_file" and specify "type=b200" in the device arguments? There should NEVER have been any reason to change the VID and PID on the device. -------------------------------------------------------------------------------- _______________________________________________ USRP-users mailing list USRP-users@lists.ettus.com http://lists.ettus.com/mailman/listinfo/usrp-users_lists.ettus.com
