[INFO] FM Driver Source from Samsung Galaxy S - Nexus One Android Development

just found it in the source released by samsung at this url
http ://opensource.samsung.com/reception/reception_main.do?method=reception_list&menu_id=4
(sorry i still can't post link yet)
seems like that device uses the same 'bcm4329' chip as in the nexus one.
so has anyone tried to compile this into the nexus one kernel yet?

---

Nice! Hoping the devs can get this working

---

This is the moment of truth. I have been waiting on this since it was first discovered that the hardware was capable.

---

I am going to assume that the source is useless, as it pertains to different hardware.

same chip though... or at least the OP thinks so.

legit! hopefully something can come of this!

FM radio of nexus like desire is on the QSD and not in bcm4329
The problem is not the source, we can use HTC Desire source, but the radio application, the HTC FM Radio app work only with the HTC framework

I'll be looking at it until froyo source drops. Will try figuring out what is needed. Don't have anything new to do until froyo source drops out. Will see if it can work with nexus

Ooooh...let's see if I can get this to work in my kernel... ;p

Awesome!!!!

Just finished downloading the source and unfortunately, it is useless to us for FM. It seems that the Galaxy doesn't use the FM in the BCM4329 chip but instead uses one from Silicon Labs (SI4709).

FM Radio is not on BCM4329 and why use the galaxy source when desire source is available?

desire is a nexus one without a second mic and noise canceling chip

That's because the Desire source doesn't contain the driver for the FM radio. If what you're saying is true, can you tell me what the desire uses as it's FM radio if not the one in the BCM4329 chip?

The desire kernel does have some FM radio drivers but it seems to use a different DSP than the Nexus one when I grepped through the kernel and the config files. I'm not sure how the FM radio is connected to userspace on the desire, but Paul mentioned that the FM radio.apk does actually work for scanning, just no audio.
I haven't managed to reproduce that locally yet, but I'm interesting in trying ...

One of the Android devs at Google I/O (Brian) said that the best way would be to look at the incredible source and figure it out from there.

I guess some education is needed to prevent some people from writing things they don't have a clue about.
QSD8250 doesn't have FM radio. Looking upon every spec on the internet, all clearly saying it, should have saved you the need for typing bullsh!t and saved me the need to interfere. And if it's not enough, let's just say that I have very credible sources as long as it's about Q.
Desire source is hard to use, because of HTC framework all throughout the apps and drivers, which we don't run on Nexus. Desire might hold almost the same HW, but it doesn't make it any less difficult for SW devs to navigate in a mess of the code they don't run, trying to replicate its functionality.
Ideally the solution would come from a phone that runs vanilla OS and uses the same radio chip and the same QSD, but there's no such phone I'm aware of.
It could come from a phone using vanilla OS and the same radio chip on a different HW, minus the audio stream handing, which should be adjusted for QSD8250 - but the problem is that the audio stream is the only thing left to handle anyway, the rest is solved by Paul on his Desire builds.
