  1. 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.

  2. 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)

    -rw-r--r-- 1 root root 12240044 Dec 20 20:35 arecord.mic.2_1513801965.wav
    -rw-r--r-- 1 root root 12240044 Dec 20 20:35 arecord.mic.3_1513801965.wav

    -rw-r--r-- 1 root root 14195044 Dec 20 20:35 arecord.mic.1_1513801965.wav

     

    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.  

     

     

  3. 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.
