Re: [Discuss-gnuradio] Removing the old version and Installing gnuradio 3.7 on USRP E 110
Hi Wafa, root@usrp-e1xx:~# swapon /swapfile1 *swapon: /swapfile1: swapon failed: Device or resource busy* The file is still opened; maybe you're already using it (check with swapon without arguments)? Have you been able to run mkswap on the file? Also, you must use an external drive to store the swap file instead of the root folder ( / ), because in the standard image on the standard 4GB flash drive that the E100 uses, there won't be enough free space for a reasonably large swap file. Regarding question 2: swap can't be too big. Aim for 3-4GB.

Re: [Discuss-gnuradio] Removing the old version and Installing gnuradio 3.7 on USRP E 110
Hi Wafa, to cite an email of Marcus Leech (which I saidly can only find myself in citations): This particular error comes from GCC running out of virtual memory during the compile. You'll need to attach an external disk, make a swapfile on it, and then attach said swapfile to the swap pool using swapon. Please consult the internet, your administrator or IT helpdesk on how to set up a swap file on linux. But your real question was: How to fix it in order to update gnuradio embedded on usrp e110? I think the answer here is that I still think it might be a bit early for you to work on the OFDM systems on your embedded device. First, you should get a little more accustomed to doing Software Radio on a PC, using simulations. After all, a simulation can give you a feeling on how much processing power you'll need to do the real-time transmission -- and if what you're planning to do is really feasible with your specific combination of hardware, system and optimization knowledge.

I recommend you spend some time with the OFDM blocks over simulated channels on your PC to become familiar with the basics. Using the E110 is not a simple task, make sure you've become fully familiar with that device before you attempt to do something sophisticated.
