<s_frit> suprothunderbolt: which SoC? have you read the data sheet?
<suprothunderbolt> RK3288, yes.
<s_frit> "Not only I2S but also PCM mode surround audio output (up to 7.1channel) and stereo input are
<s_frit> supported in I2S/PCM controller."
<s_frit> page 441
<s_frit> 8 channel output, 2 channel input
<suprothunderbolt> mmm, the 3308 seems to support a lot more channels in / out
<s_frit> 3399 has multiple parallel stereo I2S serial channels with configurable direction. up to 10 channels total
<suprothunderbolt> ahh, alas I'm looking at a lower price point.
<s_frit> i'm working on trying to multiplex more channels using an fpga. but it's early days
<suprothunderbolt> I'm currently using a am3358 (TI chip)
<s_frit> you're making a custom board?
<suprothunderbolt> if I can use a SOM that would be great
<s_frit> i see
<suprothunderbolt> I was looking at the things like : https://www.graperain.com/ARM-Embedded-RK3288-System-On-Module/ and the firefly som's
<suprothunderbolt> looking around the $35 price point.
<suprothunderbolt> with some emmc / flash
<s_frit> yeah. not a SOM, but $45: https://www.friendlyarm.com/index.php?route=product/product&product_id=241
<s_frit> what are you making?
<suprothunderbolt> the big little stuff scares me a bit
<suprothunderbolt> plus i need either MIPI DSI out or parallel RGB
<suprothunderbolt> so really looking at a SOM
<suprothunderbolt> deciding between Allwinner, Amlogic and rockchip.

<suprothunderbolt> it's for an audio project (synth)
<s_frit> cool. i'm trying to make something more like a modular audio computer
<suprothunderbolt> oh nice :)
<suprothunderbolt> S905 Amlogic seems to support i2s / tdm well.

<s_frit> i have to leave the computer now, but i'll be interested to hear how you progress.
<suprothunderbolt> you too
<s_frit> #music-electronics might be a place to keep in touch if you're on freenode often
<suprothunderbolt> sounds good
<s_frit> there are a few linux folk with relevant knowledge in #lad. I think @falktx was involved with the MOD pedal, which used Alwinner. Now they have switched to NXP I think

<suprothunderbolt> yeah, i know falktx
<suprothunderbolt> he's not with that project any more
<suprothunderbolt> neither are any of the other code people... ;)

<orion> Hi. Why are there so many blobs listed here for the rockpro64?: https://github.com/rockchip-linux/rkbin/tree/master/bin/rk33
<orion> What is their naming convention?
