arc-hs38_vdk-20150313: release for HS38 VDK

This is ARC Linux v3.13 for the VDK Family for ARC HS Processors (HS38 VDK).

Contents:

• Kernel (foss-for-synopsys-dwc-arc-processors/linux) version 3.13
• HDMI
• USB (EHCI)
• Ethernet
• UART
• rootfs
• busybox
• gdbserver
• lsusb
• dropbear ssh
• DirectFB
• Mplayer

Further documentation on how to use the VDK and compile & run Linux applications can be found in the VDK Family for ARC HS processors User Guide.

This release includes 2 sample configurations: hs38_vdk for single core and hs38_smp_vdk for multi-core.
To build, use these configuration files for buildroot, or follow the steps described in the User Guide:

# make snps_hs38_vdk_defconfig
# make

Or for the multi-core version:

# make snps_hs38_smp_vdk_defconfig
# make

Output of the build process will be a vmlinux Linux kernel image, and a rootfs.ext2 root filesystem image for use with the VDK. Please note that U-Boot is not included for the VDKs, since the vmlinux and rootfs.ext2 images are directly loaded into memory by the VDK. See the VDK User Manual for further details.

arc-axs101-20141021: maintenance release for SDP

With this release 2 Linux kernel options are available: arc-3.13 (axs101_defconfig) and arc-3.15 (axs101_arc_3_15_defconfig).

The most important reason to have arc-3.15 kernel is support of USB 1.1 peripherals which is missing in arc-3.13.

ARC Linux 3.13 for AXS101 + root file system

This is ARC Linux v3.13 for AXS101

Contents:

• Kernel (foss-for-synopsys-dwc-arc-processors/linux@bde9d98)
  • version 3.13
  • HDMI
  • USB (EHCI)
  • Ethernet
  • UART
  • SD / MMC
  • I2C
  • GPIO
• rootfs
  • busybox
  • gdbserver
  • i2c tools
  • lsusb
  • perf tools

To build, clone this repository and use the axs101_defconfig configuration file for buildroot:

# make axs101_defconfig
# make

A prebuilt version of this release is attached in the form of 2 files:

1. u-boot.bin. This is a binary image of U-Boot bootloader. Just copy it in RAM starting from offset 0x81000000 and set PC register to the same value 0x81000000. Now run CPU and U-Boot console will be seen on debug UART.
2. uImage. This can be put onto an SD card (FAT formatted, in the root directory) and loaded using u-boot with the following commands:

AXS101# fatload mmc 0
AXS101# bootm

Alternatively this file could be put on TFTP server and the in loaded in U-boot.
For it one needs to set TFTP server IP address like this:

AXS101# setenv serverip 192.168.0.100

And then get IP address via DHCP and load image with a single command:

AXS101# dhcp

Now start execution with

AXS101# bootm

There are two consoles enabled in this image: the frame buffer console (tty0) and a serial console (ttyS3). This means that you will get a command prompt on the screen that you connect via HDMI. To interact, a keyboard needs to be connected, and - as only USB 2.0 is supported - this likely needs to be connected through a USB 2.0 hub, as most keyboards are still low speed / USB 1.1!!
Alternatively, the serial port that is multiplexed on the USB cable, can be used. To interact, use a serial terminal program with settings 115200 8n1.

Important changes compared to the previous release:

• U-Boot now comes from upstream FTP (v2014.04-rc2)
• Fixed building of host U-Boot tools
• Kernel with updated memory map for AXS101
