I want to execute the usrp_echotimer_dual_cw example from the GNURadio gr-radar OOT module.
The flowgraph works fine with the internal gigabit ethernet adapter but fails with the external PCI gigabit ethernet adapter.
Here is the output of the successful execution (eth0) of the flowgraph:

02:05.0 Ethernet controller [0200]: Intel Corporation 82541PI Gigabit Ethernet Controller [8086:107c] (rev 05)
I don't think it has to do with the performance of the computer, because that flowgraph works fine on a much weaker laptop pc (intel core 2 duo), but fails on my i7 desktop pc.
00:19.0 Ethernet controller [0200]: Intel Corporation 82579LM Gigabit Network Connection [8086:1502] (rev 04)
The 82579LM is the single known non-USB gigabit ethernet adapter that randomly drops packets without giving notice to the Operating System.
I'm afraid you will have to use a different PCIe-Gigabit adapter.
By the way, L means that your packet (containing some command for the USRP to execute, normally) is later than the time that was specified for the command to happen.
The source code where the L get's printed:
else if (metadata.event_code &
async_metadata_t::EVENT_CODE_TIME_ERROR
) UHD_MSG(fastpath) << "L";
Now, EVENT_CODE_TIME_ERROR means that
Packet had time that was late.
Which might be an effect of your network card dropping packets earlier, so that somehow the timing commands got out of order, or your application got confused. Normally, it's an indication of an application misdesign, but as your network hardware definitely is buggy (seen that controller fail many times, sorry), I would fix that first before investigating further.

No matter how much packets I pump thru the pipeline, at most 153 packets are processed, the rest is dropped and nothing is sent. I'd guess those 153 packets clog the TX queue in the 00:06:00.0 and that's it.
I tried dpdk-pktgen and it sent nothing as well.
Note: the NIC used to send the packets (tcpreplay) is the same model as the one used for dpdk-testpmd.
What am I doing wrong, or what am I not doing (and I should)?

I have a custom iMX 6UL board with Barebox (partially) functional. I have on board a Semper s25hs512t Flash being detected (after adding the necessary device id indrivers/mtd/spi-nor/spi-nor.c)
The problem - My board does not have ethernet or removable SD. I need to burn the boot loader/ flash on the s25hs512. I need to format the flash accordingly and copy the files on it.
my dtsi has
&qspi {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_qspi>;
status = "okay";
flash0: s25hs512t#0 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "spansion,s25hs512t", "jedec,spi-nor";
spi-max-frequency = <40000000>;
spi-rx-bus-width = <4>;
spi-tx-bus-width = <4>;
reg = <0>;
spi-mode = <0>;
m25p,fast-read;
status = "okay";
partition#0 {
label = "barebox";
reg = <0x00000000 0x00100000>;
};
partition#1 {
label = "barebox-env";
reg = <0x00100000 0x00040000>;
};
partition#2 {
label = "barebox-of";
reg = <0x00140000 0x00040000>;
};
partition#3 {
label = "kernel";
reg = <0x00180000 0x00800000>;
};
partition#4 {
label = "root";
reg = <0x00980000 0x03640000>;
};
};
};
on boot barebox detects the flash

PS : Update
Thanks for help from #TrentP - I am focusing only on formatting the larger partitions so that I can write the kernel and root partition. but I have not been able to mount the ubi partition. I get the following issue (Readonly filesystem)

Any suggestions on what I am doing wrong. I know its something ridiculously simple. just unknown to me
You aren't supposed to use ubiformat on the barebox partition. It's too small. That's why it fails.
UBI is a Linux layer for putting UBI filesystems into NAND or NOR flash. The iMX6UL CPU boot ROM does not understand UBI. It can't boot something in a UBI formatted partition. It's for the root filesystem in the root partition.
Read section 8 of the iMX6UL reference manual, especially §8.6 about QuadSPI booting. This will tell you what you must put into flash to make it bootable.
Also look at the barebox_update command, which can be used to flash the bootloader from Barebox. The board needs to support it and I don't know about your board. The code is in various imx6_bbu_* functions. I'm not sure if qspi is supported, as I only see eMMC/SD,eMMC boot, NAND, and I2C/SPI. The qspi interface isn't the same as a serial EEPROM on one of the eCSPI controllers (again, see RM §8!). But perhaps it would work with an appropriate header already on the image.
I'm trying to run gr radar on Ubuntu 18.04 using Gnuradio 3.8.2 and keep getting the following error when using the echotimer block with two USRP N210s:

This happens when I use 2 USRPs transmit and receiving when using the gr-radar test_usrp_echotimer_cc.grc file (or any other grc file that uses the echotimer block for that matter). The grc file seems to work fine with one USRP in loopback. I'm guessing the "ERROR_CODE_LATE_COMMAND" happens when the receiver USRP needs a different waiting time to start. Any idea how to fix this? Any help is appreciated. Thanks
I'm writing some network device driver for Linux. For some reasons I have to reduce dynamically MTU for my network interface while initializing.
When the driver calculates and sets MTU to for example value 892 - kernel trims outgoing frames to 310 bytes.
The question is: why the outgoing packets are 310 bytes long instead of 892 bytes?
Edit: (part of code calculating MTU)
bitrate = 250; // [kbit/s]
limit_us = upstream_timeslot = 5000; // [us]
mtu = (limit_us - 144) * bitrate * 2 / 15625 - fp->wdev->hard_header_len - sizeof(struct ether_header);
It just calculates what is maximum value of 1 frame that fits transmission timeslot for slow transmission 250kbps.
