Ahh so for you "normal terminal to start up under the current screen" is xterm
Did you compile xterm yourself using TVs toolchain and libs ?
Good point. My next quest will be to do so. I might ask for info this week-end if I get stuck.
About the sound. SDL so libs link to GPlayer process basic sound subroutines. GPlayer doesn't run until a native application/game is run. AudioInit it is pretty simple.
However from here
https://jkry.org/ouluhack/HackingSamsun ... ebugOutput:
Code: Select all
102 btsec mod ld
103 Insmod Broadcom BT PCM Driver
104 BTPCM btpcm_ibiza_init: ibiza_pcm_buf_left_phy_addr(Default)=0x32d20000
105 mdrv_emac mod ld
106 BTPCM btpcm_ibiza_init: ibiza_pcm_buf_size(Default)=86016
107 BTPCM btpcm_ibiza_init: ibiza_pcm_left_write_phy_addr(Default)=0x32df0b14
108 ##### System ExeBTPCM btpcm_ibiza_init: ibiza_enable_mark_addr(Default)=0x32df0b66
109 cution!!! ##### btpcm mod ld
which tells me the broadcom bt pcm cards are used on these devices.
On my machine I have very similar values. However on my tv the values are being inserted by SLauncher. Not sure if this helps but you might want to populate these parameters before trying sound under X. Buffer size might differ depending on model.
Code: Select all
/mtd_exe/SLauncher root /bin/sh -c echo 0x32d20000 > /sys/module/btpcm/parameters/ibiza_pcm_buf_left_phy_addr
/mtd_exe/SLauncher root /bin/sh -c echo 0x32df0b14 > /sys/module/btpcm/parameters/ibiza_pcm_left_write_phy_addr
/mtd_exe/SLauncher root /bin/sh -c echo 0x15000 > /sys/module/btpcm/parameters/ibiza_pcm_buf_size
/mtd_exe/SLauncher root /bin/sh -c echo 0x32df0b66 > /sys/module/btpcm/parameters/ibiza_enable_mark_addr

Okay I thought I have explained but let's start from beginning. There is no such thing as "sound under X". Standard way to use sound (in linux) is trough device /dev/. No need to start X to test that
Until you get such thing working and/or find a kernel driver there is really no point in trying anything else
No command will help, no magic strings. You either find a driver or code one yourself. It doesn't matter that you have "sound on TV". NO linux app will know HOW to use it. Linux apps know ONLY linux drivers

Yes. I totally get that. But I think where I am not clear is this: isn't btpcm a kernel driver that is used for sound?
Thank you

Well it might be but until it "exports" standard linux devices that can be accessed with standard api it still means you have to rewrite it

Makes total sense. Starting now to dive into this.
Is this the right toolchain for my tv?
arm-v7a15v3r1-20121018.tar.bz2

I am using arm-v7a8v4r3. IIRC a15 didn't work for me
Not sure what will be best for you. Test

I will try it. Do you have an arm7l cpu as well? maybe that is why it doesn't work. Can't find arm-v7a8v4r3 on their site
Thank you

I think "everybody" has arm7l cpus

Thank you
you can find cross-compiling toolchains on samygo svn for sources instead just google it or ask @samsung oss.
or you can look here
