Thank you for answers guys. It seems I understand now the way I should explore.
-
I want to have my SDCard storage fully encrypted including /etc and /home so it can be used with particular OrangePI Zero board.
USB drive is not an option for me, so I thought for SPI-boot with some storage keys for SDCard.
-
Hello,
Is such configuration possible:
1. Orange Pi Zero +
2. SPI-boot with no USB storage
3. SD Card has armbian files, but it is not bootable.
I red that there is configuration with SPI-boot + USB storage, but not sure if there is a guide/possibility to continue use SD Card.
Is that possible, is there any guide?
Thank you.
-
tried mainline. it is the same.
Also one more interesting thing may be related is that it doesn't detect more than 6 USB-Audio cards. For instance I use two hubs with 4 cards each. Any 6 of them are detected fine but not more.
Or is there some limitation at usb/udev/alsa/kernel level?
-
Ok, thank you. I will start with mainlien kernel.
-
Sure.
3 cards (recording start immediately after reboot)

File sizes (you can see that two have less size while they started the same time and with absolutely same arecord and card parameters)

arecord command used for all cards (only CARD name is different among the cards):
arecord -v -r 48000 -c 1 -D plughw:CARD=Device,DEV=0 -f S16_LE -d 1800 --buffer-size=170000 --fatal-errors
kernel:
orangepizero:~$ uname -a Linux orangepizero 3.4.113-sun8i #16 SMP PREEMPT Tue Jun 13 14:15:57 CEST 2017 armv7l armv7l armv7l GNU/Linux
SD card speed. It is fast. I tested it with simultaneous recording of 10 streams with 2Mbps bitrate each with no issue. DD test:
orangepizero:~$ dd if=/dev/zero of=testfile bs=1M count=1000 oflag=direct 1000+0 records in 1000+0 records out 1048576000 bytes (1.0 GB, 1000 MiB) copied, 49.8259 s, 21.0 MB/s
And mount options:
/dev/mmcblk0p1 on /var/log.hdd type ext4 (rw,noatime,nodiratime,errors=remount-ro,commit=600)
If you want me to perform any test or try a specific configuration I am ready to make it.

Hello,
I use Orange Pi Zero + 4 ports USB hub + CM108 USB-Audio cards with mic-in.
All by default.
Each mic is captured with sipmle commands like:
arecord -v -r 44100 -c 1 -D "hw:CARD=Device_1,DEV=0" -f S16_LE > mic1.wav
When 3 cards capturing simultaneous all working well. But if I start capturing with 4th card simultaneous I get two cards with crackling recorded audio.
I even can see that arecord saves less data from these two cards (file size is less than with 3 cards). No error/warning provided anywhere (dmesg, syslog, arecord).
Moreover, if I stops recording from one card - it becomes normal for rest of them instantly.
And this strange behavious exists in all cases I tried. SImultaneous recording start for 4 cards, start recording later for 4th card, many dirfferent 4 ports USB hubs, USB 1.1, USB 2.0, different sudio cards (CM108)....
Very rarely I could get normal operation for 4th cards simultaneouly, but for the same configuration it worked bad again after restart.
Could you please suggest how I can attack this issue? Do you need any info in addition to get better view?
Thank you.
Are linux-headers-3.4.113-sun8i packages deleted from repo?

Hello,
It seems a few weeks ago linux-headers-3.4.113-sun8i package was removed from armbian repo.
Is it persistent?
How I can get it?
Thank you.
