ZTE Blade FM Radio chipset + CM7

[Guest Simon O]

I have worked on the code a little now, I had issues with the band and the step, also the Java app sends frequencies like 87500 and we need to send 8750 to the device, all this done, now it works! with the nice GUI of CM FM Radio app!

I cannot distribute an APK though since the changes are in a system C library, I'll submit the changes to the CM maintainers.

Big issue though, it keeps going off unless you change the volume, any idea about that?

I think andorko had a similar issue when he was making his own FM Radio app which kallt_kaffe fixed with a small kernel patch. The CM7 kernel will need this adding:

[Guest popoyaya]

Great work Stephane K! You appear to have achieved the impossible! Really excited to see this finally working ;)

[Guest _amano]

Stephane! Thanks for stepping up ;)

Please contact Androko because he is pretty sure that the Blade actually provides the si4709 chip and not the si4708 chip (thus he got RDS working on Froyo ROMS, a feature that is not present for the si4708). ZTE just shipped a driver for the si4708 chip in their stock kernel and therefore it SEEMED to be a 4708 chip when it was actually a 4709 hardware-wise).

I might be wrong though but that was my impression from this story. Andorko had to adapt the ZTE kernel to use the modified 4709 driver. Thus some things should have to be added on the kernel side. See Flibblesan's comment.

[Guest Stephane K.]

I am not entirely sure what chip we have but I know that the Si4709 code does not work.

In CM we have kernel 2.6.32 for the blade for a reason I don't know. We don't have the Si470* driver from stock linux, we have a weird driver that presents a device file outside v4l, it shows as /dev/si4708 . I have no idea why we have that kernel version and not the latest one in CM (2.6.37 or 38). I am not building the kernel and I am not sure where to get it from.

The C header provided at the top of this thread does not have any RDS related call anyway. I coded around that header which seems to have the right IOCTLs for the driver that is in CM's blade kernel. It works so, that's the right combination of driver + user space calls, now if we use a newer kernel with the proper linux driver, this user space code will stop working as the IOCTLs are different.

The following goes in frameworks/base/core/jni/android_hardware_fm_si4708.cpp and you need to modify the makefiles too.

In CM we have kernel 2.6.32 for the blade for a reason I don't know.

The kernel used in CM is basically the kernel ZTE released for the Froyo firmware. It includes lots of ZTE specific changes. The git for the CM Blade kernel is here. Tom_G creates images every now and then and submits the image for inclusion in the normal Cyanogen Blade device tree.

Discussing further steps is probably easiest on IRC, see the PM I sent you.

That's great to hear - a load of help - kudos to Stephane, a lil tip - use pastebin and refer to the linky on that site.... job will be much easier to copy/paste!

The weird thing is this:

Silicon Labs have the sources to Si4708 - for some obscure reason, Andorko managed to get RDS going on this chipset driver (don't ask my why) - the bizarre thing is - there's a Si4709 which does have RDS built into the driver - why hack it up on Si4708 - that's the part I do not understand...

So is the blade using a Si4708 or is it really a Si4709 but then again... ZTE made a lovely mess of the code in the .32 kernel but I digress...

It'll be great to see this going on the CM7... ;)

[Guest Stephane K.]

OK then, I thought we were using the ZTE kernel. So, my code works with the included driver. Anyone tested?

It would be interesting to see if we can move to a newer kernel, it may be a massive task depending on how many changes ZTE put in.

[Guest Stephane K.]

Tom G is working on it now, and he got the sound to stay on, it is all very promising.

On the other hand I am looking at using the Linux included driver instead of the ZTE one, with no luck thus far, but I am not giving up.

If the code is soon accepted, it will be in the nightly then.

manually build the rom. FM function is fine except that the fm app cause screen lockup and volume control not working

[Guest bhf]

It turned out that andorko's RDS FM Radio was a huge battery drainer in all Froyo ROMs. Whilst the stock non RDS FM radio was fine battery wise.

yes it drains even in sleep mode.

I prefer using non rds base version.... if we could have one like the stock version.

Hi,

It's all submitted for review now, sound works fine, and I added volume control tonight, there are quite a few patches. libaudio, FM app, jni...

Check gerrit for the patches.

It seems to work fine for me. See what you get.

Burstlam added a link to his current test build in the nightly thread.

Hi, the fm app in that build don't accept every frequency.

For example i can't select 96.6 but it jump from 96.5 to 96.7.

Can somebody check this?

Sorry ;). It Works.

I've selected the corrected country in settings menu. Thanks.

Whats the current state of FM-Radio for CM7? i read the CM7 thread and that thread but could not find out if there will be anything

in official CM7. Do the guys of cm7 for blade accept the code? Are there still problems?

[Guest Tarot]

Compiling the Build with patch from review.cyanogenmod.com. Does anyone still there is a background noise in FM? Does anyone lost sound radio when you install PowerAMP?

[Guest kallt_kaffe]

I just want to say thanks to those involved in this. I'm currently compiling CM7 for the ZTE V9/Light/Optus MyTab with the new FM radio changes. I suspect that it will work although it's still compiling.

Well, I just heard about it... Dunno yet... The time I can spare for these kind if things right now I put on the ZTE Light...

[Guest protocold]

anyone know what is the latest status of this now?

[Guest t0mm13b]

anyone know what is the latest status of this now?

Its currently in the latest nightly AFAIK :)

[Guest Holehouse]

I was glad that FM was working in CM7 so I've flashed nightly 126. However, if I change the region to Europe or UK (or anything not North America) the scan for stations doesn't work properly. if I use the scan for higher frequencies button it just goes to 87.5 (even if I was on a higher frequency) and stays there whenever I press the scan frequencies buttons. It only works if I move manually to the top frequency and scan downwards. If the region is set to North America the scan works fine but misses stations on the .even frequencies.

Any ideas as to why this is and does this affect anyone else?

I was glad that FM was working in CM7 so I've flashed nightly 126. However, if I change the region to Europe or UK (or anything not North America) the scan for stations doesn't work properly. if I use the scan for higher frequencies button it just goes to 87.5 (even if I was on a higher frequency) and stays there whenever I press the scan frequencies buttons. It only works if I move manually to the top frequency and scan downwards. If the region is set to North America the scan works fine but misses stations on the .even frequencies.

Any ideas as to why this is and does this affect anyone else?

As Holehouse confirmed this in the CM7 thread, I'll double confirm this here as these things tend to get buried quite quickly there.
