tagline: From openSUSE

Parallella

The Parallella is a single-board computer (SBC).

Technical details

  • Zynq-7010 or Zynq-7020 SoC
    • dual Cortex-A9 CPU
    • FPGA
  • 16-core Epiphany-III coprocessor (or 64-core Epiphany-IV)
  • 10/100/1000 Mbit Ethernet
  • HDMI (via FPGA)
  • USB
  • UART

Manual installation

Downstream kernel

  • Partition SD card using MBR (TODO: test GPT), with one FAT "BOOT" partition (e.g., 100MB) and one ext4 "rootfs" partition
  • Extract JeOS rootfs into rootfs partition
  • Build parallella-linux-adi.git xcomm_zynq branch using parallella_defconfig plus the usual suspects like CONFIG_FHANDLE=y, CONFIG_FANOTIFY=y, etc. and with LOADADDR=0x8000 for uImage, copy uImage into BOOT partition
  • U-Boot boots without delay, so place kernel options into zynq-parallella.dts, such as console=ttyPS0,115200 root=/dev/mmcblk0p2 rw rootwait rootfstype=ext4 (by default outputs to HDMI)
  • make dtbs, copy zynq-parallella.dtb as devicetree.dtb and uImage into BOOT partition
  • Place FPGA bitstream as parallella.bit.bin into BOOT partition

Upstream kernel

Basic support (serial console, Ethernet) has been added upstream for v3.17.

A cross-epiphany-binutils package is available already.

Cross-compilers for Epiphany are being prepared at home:a_faerber:epiphany.
