SMI driver issue #97

Open great9 opened 1 year ago

great9 commented 1 year ago

RPI 3B+ Kernel 5.4.0-1081-raspi aarch64 ubuntu focal cariboulite driver from develop_R1 branch

The driver does something to the RPI's cpu frequency.

Should be using main branch at this point. Better yet, use @konimaru 's fork for the latest fixes. See #82

I tried it. Now i can only start SoapySDRUtil -info once and afterwards I can't access the device anymore

Can you get it running on a standard RPi OS like the current bullesye?

I have things working here for the most part, on a Pi4B with standard 64bit bullseye installed. Today I transmitted on the air and received a SSB signal on 1296.1MHz with a line-of-sight station and transmitted back a carrier with the test app. Have not tried transmitting voice yet.

I would eliminate the variables, get it working, then get adventurous.

No spare SD cards and the rpi is running a service that must not be offline for too long.
