FM radio support in phh kernel

[Guest Borkata]

After all Nexus One users got FM radio.

Here is the source code in their kernel, which enables it (i.e. implementation for Serial HS driver to can handle multiple instances and some other stuff).

My question is can phh or some other kernel dev with more time and experience look into this and try to implement patches :angry:

[Guest canko20]

i thinks is easy to port on liquid...

the problem is...can we use the fm app of stream?

[Guest Borkata]

I am not sure if FM application is dependent on chip and we don't know what BCM chip has Stream, but we can try some old FM app, for example from LG devices, which have same chip as ours.

[Guest vache]

We have a BCM4325 and the Stream have a BCM4329.

Already tried to use LG Eve source, with no success.

Now playing with intersectRaven source.

@Vache I guess it's a race now, isn't it. :angry:

I'll be on IRC if you want some help.

(Just a question, which kernel branch are you using? Master/Froyo or Eclair?)

I'm using the eclair branch. And no it's not a race, but we have a least to try.

@vache N1 uses BCM4325 too, doesn't it? I read somewhere fm radio was finally enabled for this device a couple of days ago, maybe N1 kernel sources may help..

I was just joking. :angry:

Best of luck... looks like a mess to me. I think it would be best to merge the LiquidE source with IntersectRavens kernel source, which is based on 2.6.35 (latest from kernel.org). But that may or may not be possible... well... with a lot of hard work.

Nexus One have a BCM4329. The link in the 1st post is for that kernel source.

[Guest Seth Cold]

maybe using the desire fm app? like they're using on nexus?

[Guest buggle]

FM receptor on acer liquid?

I do not believe.

Acer liquid can receive FM frequencies?

Yep. the chipset itself can. Btw no drivers are provided in liquid kernel, so there's some work to do to port other device's drivers, something similar to what happened for N1, which has a working fm radio using some code from htc desire kernel.. Well, more or less, given that desire & n1 are quite the same device..

[Guest LoganX78]

There is an italian programmer that writed, a few days a go, a post on an italian forum on Radio FM near to work on Liquid. His rom will be upload tomorrow or saturday. If he will do, i'll write it here :angry:

I am pretty sure that kernel patch is not about fm support of chip, but ability tty to handle multiple request - that is why irqs are added. About chip driver it is dhd.ko and we have to recheck in public broadcom sources. If i am not wrong there was also n1 driver too for which i have seen some code for fm.

There is one chip, but two (almost) completly unrelated drivers:

-On one side there is wifi (dhd.ko), that runs completly in kernel

-On another side, there is bluetooth/FM, that runs completly in userland

(The almost is because of the bluetooth/wifi cohabitation)

There are some things concerning FM in Desire kernel, but it's only to make the sound "read" datas from the bcm4325 chip or to detect a headset. (I still don't get why they had to add that since any headset work, but eh, it's HTC, they aren't known for the proper stuff.)

[Guest LSteam]

i have edited all kernel files with this fm mod...

but...i can't compile it.

i got an error...

i have tried to compile phh kernel WITHOUT any edit...but i always got error...

can someone link me to a kernel compile tutorial?

i have installed arm toolchain and etc... but not success...
