[SOLVED] no /dev/vchiq

Postby puk » Fri Dec 30, 2016 2:40 am

Hi,may be fiddling too much with boot.cmd (to boot from external hdd) destroyed my BananaPi-ArchLinux. but may be this doesn't work in general... There isn't any /dev/vchiq device on my BananaPi? Which package or kernel-module does provide that device?

Here is the boot.cmd i'm using:
Code: Select all
part uuid mmc 0:1 uuid
setenv bootargs console=ttyS0,115200 console=tty0 console=tty1 root=/dev/sda1 rw rootfstype=ext4 elevator=deadline rootwait

if load mmc 0:0 ${kernel_addr_r} /boot/zImage; then
  if load mmc 0:0 ${fdt_addr_r} /boot/dtbs/${fdtfile}; then
    if load mmc 0:0 ${ramdisk_addr_r} /boot/initramfs-linux.img; then
      bootz ${kernel_addr_r} ${ramdisk_addr_r}:${filesize} ${fdt_addr_r};
    else
      bootz ${kernel_addr_r} - ${fdt_addr_r};
    fi;
  fi;
fi

if load mmc 0:0 0x48000000 /boot/uImage; then
  if load mmc 0:0 0x43000000 /boot/script.bin; then
    setenv bootm_boot_mode sec;
    bootm 0x48000000;
  fi;
fi


Nice to be here and thank you for your information and help. I'm searching for days to solve the issue :(

Vchiq is specific to videocore on raspberry pi. Why would you need it anyway for booting?

kodi crashes while missing /dev/vchiq. and the bananapi uses the same Allwinner A20 CPU the Rasbpi ist build on. but to be honest, i have no deep understanding of the A20 Hardware and need new ideas to solve this issue. dmesg doesn't show a line containing vchiq so the device has no idea that it has to generate that device?!
thank you for your help.

Raspberry Pi uses Broadcom BCM2835/6/7 and not allwinner. Completely different hardware.

Banana Pi uses Mali GPU and thow needs mali kernel module loaded. it isn't included in the default kernel for armv7!
And no (modern) linux kernel for Banana is provided. Problem is solved i think! Thanks for the friendly help.

We don't officially support BananaPi so you won't find any specific to BananaPi bits and pieces in our repo.
