This document provides information about Digi Embedded Yocto,
|
||||
Digi International's professional embedded Yocto development environment.
|
||||
|
||||
Digi Embedded Yocto 2.4 is based on the Yocto Project(TM) 2.4 (Rocko) release.
|
||||
|
||||
This is a beta release for the ConnectCore 8X SBC Express. The rest of the
|
||||
platforms are supported but have not been fully tested.

# Release Changelog
|
||||
|
||||
## 2.4-r2-beta
|
||||
|
||||
* Added support for ConnectCore 8X platform. Supported features:
|
||||
* Bluetooth and Wireless interfaces (STA, SoftAP, P2P, Concurrence)
|
||||
* MCA: Reset, Watchdog, RTC, GPIOs and ADCs
|
||||
* SBC Express interfaces: Ethernet, microSD, UART, I2C, CAN, SPI, USB host,
|
||||
USB device, GPIOs, XBee, LVDS Display, Touch Screen controller
|
||||
* Graphics and Video
|
||||
* Updated U-Boot to version 2017.03-r1
|
||||
* Fixed XBee RESET_N polarity assertion. Requires updating polarity of the
|
||||
``digi,reset-gpio`` property of node ``xbee`` on device tree files derived from
|
||||
ConnectCore 6UL SBC Pro to use polarity **GPIO_ACTIVE_LOW**
|
||||
|
||||
## 2.4-r1
|
||||
|
||||
* Release based on [Yocto 2.4 (Rocko)](https://www.yoctoproject.org/downloads/core/rocko24) including:

* The Micrel PHY KSZ9031 may take between five and six seconds to
|

auto-negotiate with Gigabit switches.
|

|
||||
## ConnectCore 8X
|
||||
|
||||
* i.MX8QXP Processor
|
||||
* The following processor features are not supported in this BSP release:
|
||||
Power Management, PWM, ADC, RS485. They will be implemented in future releases.
|
||||
* VPU unit is not fully functional, hence hardware video encoding/decoding is
|
||||
not available. On this release, video encoding/decoding can be done via
|
||||
software plugins, reducing the performance of video playback. This will be
|
||||
available in future releases of the hardware.
|
||||
* GPU maximum performance reduced. The maximum frequency targets are 850 MHz
|
||||
for the shaders and 700 MHz for the core. However, in this hardware release
|
||||
the maximum frequency is limited to 650 MHz for the shaders and 600 MHz for
|
||||
the core, with the corresponding performance reduction. These targets will
|
||||
be met in future releases of the hardware.
|
||||
* BSDL operation is not supported. It will be available in future releases
|
||||
of the hardware.
|
||||
* ConnectCore 8X System-on-Module (SOM)
|
||||
* The UART connected to the Bluetooth chip on early versions of the ConnectCore
|
||||
8X System-on-Module (hardware version = 1) cannot properly execute flow
|
||||
control. To work around this issue, UART1 of these SOM versions has been
|
||||
configured to operate at 115200 bps and without hardware flow control,
|
||||
reducing the maximum throughput of this interface. It will be fixed in
|
||||
future releases of the hardware.
|
||||
* MCA firmware cannot be updated without a debugger on early versions of the
|
||||
ConnectCore 8X System-on-Module (hardware version = 1). It will be fixed in
|
||||
future releases of the hardware.
|
||||
* MCA internal voltage reference cannot be enabled on early versions of the
|
||||
ConnectCore 8X System-on-Module (hardware version = 1). It will be fixed in
|
||||
future releases of the hardware.
|
||||
* MCA tamper pins configuration is not supported. It will be available in
|
||||
future releases.
|
||||
* Trustfence (TM) is not supported. It will be available in future releases.
