Re: Still can't get KSDR working (Raspberry Pi 4)

This situation is completely provoked by the KSDR developers and the inaction of technical support! (if it does exist at all - I am not sure) :x And this is the manual how to fix it! If you have RPI 4 REV1.4, you're in trouble. RAM size doesn't matter. 2GB boards affected as well. Don't know anythin...

Re: Still can't get KSDR working (Raspberry Pi 4)

Got partially working RPI with 1.6.1 image by enabling ssh (put file to the root).
Hardware keyboard and mouse still doesn't work.
But I can login via SSH and work in console mode.
Ethernet port is also works fine and I can do apt-get, etc.
So RPI is fully operational.

Re: Still can't get KSDR working (Raspberry Pi 4)

Measured voltage between TP1 and TP2 when Raspbian is loaded and keyboard and mouse are connected, is +5.117VDC. Where RPI's FAQ says that good PS can be determined by finding 4.75VDC or above on these test points.

Re: Still can't get KSDR working (Raspberry Pi 4)

What else I can do with power? If I already tried TP Link 3A active USB hub as power adapter, AUKEY 36W USB power adapter (3A+), and 5 different cables - both microUSB for KSDR and Type C for RPU? And how Raspbian OS works just fine on this RPI? With no any hardware changes? And keyboard works just ...

Re: Still can't get KSDR working (Raspberry Pi 4)

Does this image (1.6.1) supports keyboard and mouse at ll? If YES, even after OS boot (hot plug)?

Re: Still can't get KSDR working (Raspberry Pi 4)

Of course, I am not so stupid to do not do that, and I got some experience during 2 weeks of plays with this toy. E.g. I got it working on laptop first, if you remember my other thread.

Still can't get KSDR working (Raspberry Pi 4)

Hi all! I was able to boot Raspberry Pi 1.6.1 image for KSDR. It was not easy as snap of fingers, but I did that without any help from community. Now, when I got it running and connected external monitor via HDMI, I see Linux Desktop and KSDR software over it. I can control frequency on Raspberry Pi...

Re: Raspberry Pi 4 cannot boot

Did I understand correctly that the product is raw, unfinished, and has no technical support? I have to fix the errors of by myself instead of developers who for months have not been able to release a correctly working images? Both RPI and Tinker?
