OK, I see now what you were doing different. I think I could deal with leaving the /data partition the same size and increasing the two filesystems. I was just trying to save myself the hassle of performing a mender update down the road and forgetting that the data in ~/ wasn't persistent. I gu

  My understanding of the partiitons on the card are (in order); Mender allows you to boot from one of the A/B partitions as your primary filesystem (mounted as /), plus the persistent data (mounted as /home/ or /data or similar).  My experience is if you perform resizing while keeping the partiti

Chris, thanks for the tips. So I put a fresh load on a card, then used gparted to extend the data partition to fill things out. That isn't enough, and your instructions certainly show more steps. But I don't understand what you mean with the partitions in the middle. I'll read up on Mender and

  Hi Jason, I've had luck with the following:- backup/clone the original SDCard image to disk and/or larger SDCard (using dd or otherwise)- on the new card, resize/shift the data partion to the end of the card (using gparted)- resize the two filesystem/kernel partitions to fill in the empty space i

What does your network setup look like? Could you please provide the SFP+ card and the motherboard you are using on the host side? Alternatively, if you are using some adapters (SFP+ to cat 6 RJ45 to thunderbolt) please provide that as well or instead. Thanks, Ali On Wed, Jun 19, 2019 at 12:21

Hi Jessica, What sample rate are you trying to run at per channel? I would suggest to use DPDK as it will remove a considerable overhead from the Linux networking stack. I can follow up with you off the list with some notes I have on getting DPDK going, we have a pending app note that will be pu

Can you post the flowgraph you're using again? If you changed transmit gain and amplitude, the result should have changed in amplitude, while the image you just sent has the fame magnitude the last one did. On Wed, Jun 19, 2019, 5:03 AM Simona Sibio wrote: > Thank you very much. > I tried to sen
