jas-hacks_: haven't dumped the uart yet.. I have another board now which I will dump it from
<dgp>
BT works in Android.. but I need to finish this work off before I kill another board ;)
<jas-hacks_>
dgp: ok thanks. For Android you used the original hicattach?
<hste>
jas-hacks_: tried the xmbc build from wolfgar? I couldn't get it to work. It starts up the yocto screen but after that it stops for me
<jas-hacks_>
hste: haven't had time
<jas-hacks_>
hste: I guess you could try to replace the kernel with your own one
<dgp>
jas-hacks_: yeah, I'm going to test out my patched up hciattach again at some point
<dgp>
I tried bringing up freescales android 4.2.2 kernel today but it makes android 4.1.2 puke so I'm not going to touch that stuff until I have a lot of free time
<jas-hacks_>
dgp: The one from the RD5876 source doesn't work well for me
<dgp>
jas-hacks_: Do you have the original binary?
<dgp>
you could probably extract the lumps it's sending from that
<jas-hacks_>
by looking for the symbols in the binary?
<dgp>
mmm if you run it in strace under android you can see the calls to write().. I could do that
<jas-hacks_>
if you wouldn't mind that would help
<dgp>
ok, maybe tomorrow, have to get this NFC shit working and then I can play around :)
<jas-hacks_>
which board did you get for NFC?
<dgp>
sim module from a nexus s
<dgp>
it's the only thing with a PN544 on it that I could get my hands on
<jas-hacks_>
Ah, I thought you were going for the cheaper PN532 dev boards
<dgp>
we tried that.. libnfc in android is not the opensource libnfc that supports the pn532 :(
<dgp>
android has about 3 different things called libnfc that are all tied to a vendor's chip
<dgp>
I suggested just using the pn532 and skipping the Android API for NFC but I think they want stuff like beam to work, so it's fully integrated or nothing
<jas-hacks_>
and you couldn't use one of the usb boards
<dgp>
which usb boards?
<dgp>
for the built in NFC stack it has to be a pn544 over I2C or UART
<jas-hacks_>
ACR122U
<dgp>
The PN533 (I think?) with a USB host interface isn't supported as all of the important bits of the NFC stack are in the PN544 firmware
<dgp>
The ACR122U doesn't integrate with the Android NFC stack AFAIK
<jas-hacks_>
So Android NFC isn't that open
<dgp>
NXP supplied the first NFC stack as opensource but basically locked it to their chips by putting the brains on the 8051 in the chip
<dgp>
TI and Broadcom have alternative stacks for their chips.. getting those chips is hard and they don't work with NXP stuff like older mifare cards etc IIRC
<jas-hacks_>
I'm planning to take the latest kernel branch 4.0.0 and rework our kernel changes. I'd like to refactor board-mx6q_hdmidongle.c to board-mx6q_gk802.c. This way if we need to merge our changes to future kernels it should be easier to manage.
<dgp>
Have you registered a machine ID yet?
<jas-hacks_>
nope
<dgp>
Even if it doesn't go mainline it would be good to have an ID that isn't going to get used
<jas-hacks_>
Please shout if there are issues with my suggestion.
<dgp>
The 4.0.0 android kernel breaks Android's opengl stuff. Not sure if that'll cause issues with your video stuff
<jas-hacks_>
... I'll try it out in my repo first
<dgp>
no interest in having an android kernel etc in the github project? ;p
<jas-hacks_>
Yes we should one
<dgp>
not sure what to do with the android source as it's a massive lump of AOSP source + freescales hacks and external applications
<hste>
dgp: how far have u come? still many issues?
<dgp>
hste: basic android 4.1.2 all works, wifi and bt
<hste>
:)
<dgp>
you get a 6gb of storage on the sdcard
<dgp>
actually, I haven't tested if video is hardware accelerated. It should be if freescales blobs support it
<hste>
dgp: would it work with jas multi uboot?
<jas-hacks_>
dgp: you could sell it back to richtechie :)
<dgp>
hste: it needs a uboot with support for android kernel + root ramdisk images really
<dgp>
the uboot I have supports android's fastboot stuff apparently
<dgp>
jas-hacks_: it wasn't that much work to be honest. The freescale stuff was mostly there, the wandboard guys bundled it all up and being able to read the original boot.img stuff gave me all the hints I needed about how the original image was doing things
