Zephyr SDK 0.9.5 Release

Nashif, Anas


As announced a few weeks ago, we have been working on a new version of the SDK with updates mostly to the host tools.

This release of the SDK has the following changes as compared with 0.9.3:


·       New QEMU release (based on 3.0.0+git 19b599f7664b2ebfd0f405fb79c14dd241557452)

·       Qemu installation now has all needed ROMs and BIOS files to support connecting Ethernet drivers such as the Intel e1000.

·       New OpenOCD based master with Zephyr related changes (commit: 05e0d633)

·       New DTC version 1.4.7+git (commit 2e930b7f8f6421638869a04b00297034c42e1a82)

·       Upgrade arc binutils to 2018.03-rc2


The above changes and especially the Qemu related items require that you move to the new SDK ASAP, earlier version will not work with the master tree. In Zephyr, we have made the following changes based on the new SDK:


·       RISCV32 Qemu is now using a different machine type. Qemu-riscv32 is now an alias to the hifive1 board which can be run in Qemu as well.

·       NIOS2 Qemu is now using a different UART driver

·       ARM Qemu is now supported by two machine types:

o   mps2_an385: This one will be the default target for sanitycheck and will be used for testing kernel features. This machine type does have MPU support and will enable userspace testing on ARM

o   lm3s6965evb: This is the machine type we have now, we will keep it for compatibility and testing some networking and Bluetooth related features. It might be obsoleted in favor of the above in the future.


CI will be updated with the new SDK and sanitycheck will require the new SDK to pass, meaning that if you run sanitycheck locally you will need this SDK. We now made this version required for building Zephyr.
