Hello Casey, I was trying to delete DPDK files manually (because i installed DPDK 19 at first, and it doesnt have an uninstall method), and accidentally crashed my OS (it was my fault, deleted something important). After reinstalling Ubuntu, i installed everything again and the error was gone. Reinstalling everything took like 3-4 hours, i spent much more trying the fix the error. I also faced a few more errors in next steps, i mention them below, might be useful for some people.
1) It was something about invalid elf headers. DPDK tries to compile everything in the uhf.conf - dpdk_driver location. In my case, "/usr/local/lib/x86_64-linux-gnu/dpdk/pmds-18.11" file had only librte_pmd and librte_mempool dynamic libraries, so using this address fixed the error. 2) DPDK was not able to find the device, because i used capital letters in the mac address of uhd.conf. They should be lowercase. 3) "[ERROR] [RFNOC::GRAPH] IO Error during GSM initialization. EnvironmentError: IOError: Timed out getting recv buff for management transaction". I realized this error occurs with or without using DPDK, and rarely it was working correctly (but mostly didnt work). I changed fpga image to default (HG or 1 GbE, and 10 GbE sfp+), also reinstalled embedded linux with mender. The problem was gone. Then, i installed dual 10 GbE sfp+ image (XG), and haven't faced the same problem. My new problem is that DPDK is slower than without using DPDK. I sent a new mail about it today, still waiting for suggestions. GL with your setup, i have spent my whole week to get DPDK working. Berkay S. On Thu, 10 Jun 2021 at 20:56, Wolsieffer, Carl L.
