Does anyone know of an assembly place for PCBs and can you tell me the name of this place?
<set_>
Google is messing around again...
<set_>
I find these places online. Right, so. Then, I try to integrate my info. into their site online. I get questions like, "How many holes do you need?"
<set_>
It is a question that may deserve some answer but...
<set_>
Holes?
<set_>
What?
<set_>
How about, "How much area is left after you remove holes?"
<set_>
Some place asked me about how many TH and SM parts there were... This sounds reasonable, right. I check my pick and place file. So, this is not reasonable. I am paying them to handle issues. Issues in this sense is exactly the mfg. of the part w/ holes, area w/out holes, and how far apart are these areas w/ or w/out holes.
<set_>
Anyway...
<set_>
I am going to lengths to handle the concerns of this Cape making.
<set_>
Holes!

Outside of that idea, has anyone made a Cape when asked how many holes one needs for pricing?

Hi everyone, I want to ask something really quick, after run sudo tools/update_kernel.sh ,gives these errors end of the installation. The board is BBB wireless and Debian Buster IoT Image 2020-04-06
<Emre>
E: Unable to locate package seeed-modules-4.19.94-ti-r68
<Emre>
E: Couldn't find any package by glob 'seeed-modules-4.19.94-ti-r68'
<Emre>
E: Couldn't find any package by regex 'seeed-modules-4.19.94-ti-r68'
<zmatt>
seeed-modules-4.19.94-ti-r64 seems to be the latest version of that package for some reason. no idea what these modules are anyway ( https://pastebin.com/yxjbDELn )
<zmatt>
unless you have a specific need for one of these I wouldn't worry about it
<zmatt>
I don't have this package installed on any beaglebone
<Emre>
Actually,I just want to update kernel.I dont know if i need them,maybe it will cause problems in the future. Robotcontrol library seems okey, tests were succesfull. However, user leds are not blinking because of unsuccesfull kernel update
<zmatt>
uhhhh
<zmatt>
nothing you shared sounds like the update was unsuccessful
<zmatt>
what do you mean the user leds are not blinking?
<zmatt>
it just sounds like it skipped installing the seed-modules package, which is optional anyway
<zmatt>
it's still odd, but it shouldn't cause problems
<Emre>
Only wi-fi, bluetooth and power leds are operating on the board
<zmatt>
that sounds really strange, hold on let me try this kernel
<Emre>
May be, the skipped installing is not a problem. I thought that way
<Emre>
Let me share version.sh logs
<zmatt>
(note: don't paste multi-line stuff into chat, use a paste service like pastebin.com )
<zmatt>
user leds seem to be working fine on 4.19.94-ti-r68 for me
<Emre>
okey , by the way thank you so much for your help, I am waiting the BBB to initialize
<Emre>
bb-cape-overlays is already the newest version
<zmatt>
rcn-ee_: looks like kernel 4.19.94-ti-r68 has a DT issue on the bbbw ?
<zmatt>
Emre: my suggestion would be to just go back to an older kernel until this issue is solved
<zmatt>
(the kernel to boot is selected by the uname_r variable in /boot/uEnv.txt .. be sure to set it to a kernel that's actually installed by checking the contents of /boot)
<Emre>
Could you check my uEnv.txt https://pastebin.com/u/emreduman. By the way, It is not a big problem for me, I am just afraid of that can cause problem in future for my project
<zmatt>
I mean, what's there to check... it's just the default settings
<Emre>
Okey then my bad, thank you again

Hello:)
<Guest75>
I'm working on audio cape for BBAI (BBB) and want to ensure that it'll not block HDMI audio. If I have looked corectly HDMI audio has shared pins with P9.28-31, is that true? becouse somewhere else I read that HDMI audio is on/through McASP0.
<zmatt>
BBB or BBAI ?
<Guest75>
BBAI
<zmatt>
HDMI on BBAI is not shared with any other resource
<Guest75>
So it is on McASP0 as I read
<Guest75>
And on BBB?
<zmatt>
I don't think it uses any McASP on the BBAI but I might be wrong about that
<Guest75>
I want to be sure to have "universal" cape
<Guest75>
I'll try to find that McASP
<zmatt>
I'm not sure if it's possible to make an audio cape that works on both without conflicting with HDMI audio
<zmatt>
*without conflicting with HDMI audio on the BBB
<Guest75>
Oh, what a pitty
<zmatt>
https://goo.gl/jiazTL#gid=1779159674 this compares the McASP instances/pins available on the BBB vs BBAI and highlights their intersection
<Guest75>
Hopefully last question:) I see that BBB has onboard oscilator "An on-board 24.576 MHz oscillator" but in BBAI schematic there is no such osc, do I have to supply one? or is there some sort of internal multiplier/divider
<zmatt>
the BBAI doesn't have a dedicated 24.576 MHz osc because it has way more flexible options for internal clock generation
<zmatt>
so it can generate that clock internally can output it on tx hclk if needed
<zmatt>
*and output it
<Guest75>
So its more SW work than HW :)
<Guest75>
Thanks a lot, again :)
<zmatt>
probably just a matter of appropriate DT configuration
<zmatt>
the closest you could get with supporting both BBB and BBAI while preserving HDMI audio on the BBB is by using the same pins for hclk/clk/fs but different pins for data (P9.30 and P9.41 are the options available)
<zmatt>
though it would mean that HDMI audio show up as two extra channels on your audio device (and in particular your cape and hdmi audio would need to use the same samplerate)
<Guest75>
Yea that could work, HDMI as master, as it is in TI guide.... also, wanted the possibility of stacking more audio capes, which I hope have managed, but from what i can see only for BBAI
<zmatt>
the hdmi framer on the BBB is not a TI device
<zmatt>
that document is just showing examples
<zmatt>
there's no mclk on this hdmi framer afaik, or if it has one it's not hooked up
<Guest75>
But it is using McASP, which (if it reciving data) is working as a slave
<zmatt>
master/slave has nothing to do with whether you're transmitting or receiving data
<zmatt>
it has to do with which side is providing the bitclock and framesync
<Guest75>
yeah my bad... 100 times and still same mistake
<zmatt>
normally the 24.576 MHz osc provides a master clock to McASP 0, which uses it to generate and output the 48 kHz framesync and 1.536 MHz (I think) bitclock
<zmatt>
note also that typically the rx section of McASP is synchronized to the tx section, so even for receiving data you're using tx clk and tx fs (either as output if master or input if slave)
<zmatt>
(McASP supports using independent clocks for tx and rx but the linux driver doesn't support this feature)
<zmatt>
(so don't be confused into thinking "tx clk" (aclkx) necessarily means it's a clock output, the "tx" means it's the clock pin of the transmit section, but that clock may still be either input or output)
<Guest75>
ok thanks one more :)
