Zhongren, I am not sure that this will help you, but one of the things that I did when working with the E31x was to install everything to ~/localhost and leave the default stuff alone. I then created a setup_env.sh for those new files (similar to what pybombs does), and run that before I using my custom stuff.
This allows the default stuff to stay there in case I want to test with it again. It also keeps all of my stuff in a single folder that I can then blow away if I want. Good luck! ________________________________ From: USRP-users <usrp-users-boun...@lists.ettus.com> on behalf of zcao--- via USRP-users <usrp-users@lists.ettus.com> Sent: Monday, November 4, 2019 3:25 PM To: Philip Balister <phi...@balister.org> Cc: USRP-users <USRP-users@lists.ettus.com> Subject: Re: [USRP-users] Problems when Running UHD_3.14.1 Examples on E310 Philip, Thanks for the response. That’s what we did to get through the issue. But is it what we supposed to do, i.e., edit these UHD provided python scripts manually?

The process we took are as the following. 1. Flash a fresh SDcard using the dev image located at http://files.ettus.com/e3xx_images/e3xx-release-4/ettus-e3xx-sg3/<https://urldefense.proofpoint.com/v2/url?u=http-3A__files.ettus.com_e3xx-5Fimages_e3xx-2Drelease-2D4_ettus-2De3xx-2Dsg3_&d=DwMFaQ&c=euGZstcaTDllvimEN8b7jXrwqOf-v5A_CdpgnVfiiMM&r=W_MQLyUWPXWHfsF4mr51mTMqpeO4RbBBLexficV9DG8&m=BqKFEhCjIyH_Wt0BKhMuJ7WuKNliqtjAQnzUTDZl0uE&s=41C6cQDFwbYWuSCMDK9Be4hZSEYzwS5dapTh9xXRs2U&e=> <http://files.ettus.com/e3xx_images/e3xx-release-4/ettus-e3xx-sg3/<https://urldefense.proofpoint.com/v2/url?u=http-3A__files.ettus.com_e3xx-5Fimages_e3xx-2Drelease-2D4_ettus-2De3xx-2Dsg3_&d=DwMFaQ&c=euGZstcaTDllvimEN8b7jXrwqOf-v5A_CdpgnVfiiMM&r=W_MQLyUWPXWHfsF4mr51mTMqpeO4RbBBLexficV9DG8&m=BqKFEhCjIyH_Wt0BKhMuJ7WuKNliqtjAQnzUTDZl0uE&s=41C6cQDFwbYWuSCMDK9Be4hZSEYzwS5dapTh9xXRs2U&e=>> 2. Cross-compile UHD source code on a development machine and install the build on to the E310 device using sshfs. Note that this is a different from what is proposed in AN-311. We installed UHD 3.14 onto the device directly. 3. Running /usr/bin/uhd_find_devices, we got the following output, looks normal. [INFO] [UHD] linux; GNU C++ version 4.9.2; Boost_105700; UHD_3.14.1.1-0-g0347a6d8 -------------------------------------------------- -- UHD Device 0 -------------------------------------------------- Device Address: serial: 31819A1 name: node: /dev/axi_fpga product: E3XX SG3 type: e3x0 However, we ran into the following problems, which seem to be related. 1. We cannot run /usr/bin/uhd_usrp_probe, because of the FPGA compatibility. Specifically, the error messages are Error: RuntimeError: Expected FPGA compatibility number 255.x, but got 14.0: The FPGA build is not compatible with the host code build. Please run: "/usr/lib/uhd/utils/uhd_images_downloader.py" 2. But running the above python script gives us the following error messages. -sh: /usr/lib/uhd/utils/uhd_images_downloader.py: /usr/local/oecore-x86_64/sysroots/x86_64-oesdk-linux/usr/bin/python2: bad interpreter: No such file or directory/ Look at the script /usr/lib/uhd/utils/uhd_images_downloader.py and edit the #!/bin/fo/bar/python to something reasonable. Philip Note that the python script is looking for the SDK, which should be on the development machine, instead of the device itself. Would really appreciate it if anyone knows how to handle above issues in E310 device itself?
