64bit testing

I downloaded the latest May2021 raspberry64bOS (still in beta) and ran the script things seem to work for the most part ? FL-suite needed a manual install of > libfltk1.3-dev Libjpeg-dev libxcursor-dev libfontconfig1-dev libxinerama-dev libxft-dev libsamplerate-dev libsndfile1-dev libportaudio19-dev? to run the automated compile scripts, after added things seem ok! qsstv has a hamlib-dev problem and JS8 package has issues it appears. anyway I went down the path for better performance with FT8 |

开云体育For Ham Radio type applications, I don't think he will see much of an improvement in terms of lower CPU utilization across the cores.? He *will* see increased memory and storage space utilization as everything is bigger in 64bit land.? There are many reasonable and real world reasons why Raspberry Pi OS is still on 32bit... there just isn't much benefit for 64bit at this level of hardware. --David KI6ZHD On 05/22/2021 02:04 AM, Larry K8UT

There is a lot of data on this you can Google it I don’t care much to share after that bit of telling you all what I experience. But to keep it short my current pi3 is not decoding fast enough for my likes and there is a lot of good evidence to show the improvement but don’t take my word for it 32bit works fine!? But honestly I don’t care to write the detailed email response anymore I was going to GL 73? I will be working with some of the app developers to fix compile on stuff feel free to contact me direct if you have questions.? Excuse typos and brevity, sent from a mobile device.

Be curious to see back to back tests of the 32 bit build and the 64 bit for any differences in speed on the FT8.? The libraries you had to download to make the compile scripts work were all 32 bit.

Wow. He was stating facts of what 64 bit vs 32 bit on the pi have been seen by everyone but you it seems.? He wasn't stating what you saw, but what you will see.? Have you programmed in a 64 bit vs 32 bit before?? Arrays are twice the size, hence the higher memory usage and storage space.? The holier than thou attitude you are taking is why fewer people are wanting to be hams.? They see people like you, given someone else's experiences towards something you are doing and you become hostile.? They don't want anything to do with that kind of attitude.? Maybe you should re-read that post a few times, and learn to not consider someone's real world experiences that differ from what you *want* to see a personal attack.?

开云体育Pre-built ARM64 packages of Raspberry Pi OS is posted on the WSJT-X website: ?? ?? An interesting write up on deep decode times on various Raspberry Pi hardware versions can be seen here but all results there are 32bit only: ?? --David KI6ZHD On 05/22/2021 10:37 AM, N5XMT wrote:

开云体育I have loaded wsjtx_2.4.0...? It runs fine.? I can't get Audio {C-Media does not show either wsjt-x or Pulse}
to work... {works fine 32 bit} pi@rasp64:~ $
lsusb any ideas?? I
have tried with/without Pulse Audio...? BAP: BTW, conky
does not show temp.?? I have added temp to the status bar. 73, steve WB3LGC On 5/22/21 2:50 PM, David Ranch wrote:

The vcgencmd moved directories from 32 to 64 bit. ?It moved from /opt/vc/bin to /usr/bin. ?Edit the conkyrc file.
Did you go into raspi-config to check your audio settings? I finally got wsjtx 2.4.0 64 bit, GridTracker (32 bit), fldigi 64 bit and flrig 64 bit all running today. ?Very pleased with the performance. |
开云体育Is your error?("cannot find the slot for index", and "cannot create card instance"), I edited my /etc/modprobe.d/alsa.conf file changing lines like these:options snd cards_limit=2 options snd-usb-audio index=2
