Sorry for the delay, I was travelling last week. Turns out I missed some machine type setting in some of the machines when doing the forward port. Fix pushed.
Thanks Liam for the updates. I forgot to reply, I've did some hacks and finally got qemu working.
Now I get a timeout when trying to boot the DSP, but will get back with more details once I have some spare time.
Fwiw, firmware will send a FW ready message to the host to indicate boot complete. This involves writing to a special shim register that causes an IRQ on the host side.
Finally got a chance to get back to this.
First run I got a crash, which I think it's due to a race condition.
Yeah, I've not root caused that yet, had to hack around it when I upgraded to the latest qemu release.
I'm using:
- sof.git/master - 19e48c5 Merge branch '1.1-stable'
Can you also use the 1.1-stable branch for the sof tools and topology.
Sure.
- osadsp-qemu/master - 771e78b FIXME: log: Support 64bit trace format.
- asoc/sof-v4.15 - 130e9f7 0day warnings
Best to use my Pierre's v4.14 stable branch here as we are in the middle of a release (meaning my branches have more experiment patches).
https://github.com/plbossart/sound.git #topic/sof-v4.14
All right. Will give it a try.
Running
$ ./xtensa-host.sh byt $ ./x86-host.sh byt
I get the following crash:

I guess this is a race and fixed it with:
great, thanks ! Can you send that as a patch with your SoB ?
All right. Which branch should I base it on?

But what does rmbox show ?
Never used rmbox. Can you provide an example.
Another comment:
Can you let me know which configuration worked for you on Qemu?
Using default {xtensa|x86}-host.sh scripts with baytrail parameter i cannot get it working.
I have figured out that I also need a topology file.
I have used both byt-rt5640 machine Or hacked to used the nocodec but still at some point I get a timeout from
I expect that if everything works well a sound card device should be created and I can list it using arecord -l or aplay -l. Then I can use aplay/arecord to send a file to DSP for decoding.
thanks, Daniel.
