WSPR "image" ?

Post by n9qnz » Sun Jul 14, 2019 2:41 am

Hi all,

I need a little help and I'm guessing I am missing something obvious.

Pavel's web page on his WSPR transceiver includes a link to an "image" but the zip file doesn't seem to contain an image. In the interest of being thorough, I watched a youtube video and read a couple other sites on this and it appears at that time, a debian image was available. Now, the zip file contains a directory tree of files.

Here is the name of the zip containing the files: red-pitaya-alpine-3.9-armv7-20190527.zip

I know the SD card filesystem is well described on the RP web page....

...however, I am not sure exactly where to copy the files from this zip file.

Can someone give me a hint here?

thanks,
Dave

Ok, so I used an SD I had created previously for the primary Red Pitaya setup, removed the files from the 128 MB partition and replaced them with the files from the WSPR zip. This seems to have worked.

Now, I need to figure out how to ssh to the RP. I don't know what the default root password is. It does not seem to be root.

I guess it's time for the console cable.

I'll continue to post here as I hope this will help someone else down the road.

The console cable works fine. Next problem is the filesystem mounts as read-only. Editing /etc/fstab does not seem to fix this. Temporarily changing to rw works but it reverts to read-only after reboot.

There must be something fundamental I'm missing here......

And the answer is:

lbu commit -d

That command needs to be run after making changes to commit those change to the sd card.

This is apparently a "thing" unique to Alpine linux???

Well, I hope this helps someone else...
