AM335x SYSBIOS Industrial SDK 01.00.00.03 Release Notes

April 02, 2012

Introduction

The SYSBIOS-based software development kit (SDK) for industrial communications is designed for the Sitara AM335x ARM Cortex-A8 microprocessor family to enable customers add real-time industrial communications easily and quickly to their system. By making all the basic system software components immediately available, the Kit allows developers to focus on their application code, where they can add the most differentiation. Optimized to support real-time industrial communications protocols such as EtherCAT, Profibus, Profinet, Ethernet/IP and many others, the SDK includes a real-time, low-footprint SYSBIOS kernel with boot loader and sample industrial applications to get started quickly.

What Is Not Supported

• In general, peripherals or features not mentioned as part of "What is Supported" section are not supported
• For EtherCAT Slave Controller, the following features are not supported in this release
  • Distributed Clocks (DC)
  • Enhanced Link detection
  • Redundancy
  • LRW for process data
  • PDI side register permissions
  • PDI side support for 16/32 bit access
  • AP/FP/BRW/LRW for SM mapped area
  • ECAT side register protection for LRD
  • AL Event mask support

New In This Release

• Run Time hardware detection - automatically detect ICE/IDK at run time so that single application binary can run on both.
• NOR boot support on ICE - Enhance ICE bootloader for NOR boot support and eXecute In Place(XIP) from NOR Flash
• Cache-Locking feature
• Enhance the EtherCAT example application to demonstrate the following. New build configurations added to support the below features
  • Demonstrate XIP and Cache-Locking.
  • Demonstrate DDR-less operation both with NOR XIP, SPI boot and using only the internal on-chip memory
• NOR Flasher Tool - CCS based program to Flash/Erase NOR

NOTE

•  To support different Load and Run address for applications, SDK has introduced  a new header for application binaries. Hence the binaries generated with older version of SDK will not be compatible with this version's boot loader and vice versa. User's of old SDK version are adviced to migrate thier applications and bootloader to this version.
  

Fixed In This Release

None

Known Issues And Limitations

Issue Identifier	Issue Description	Workaround
SDOCM00088882	On ICE board, UART Echo application does not echo characters sent from UART Console application.	None
	Non ECAT frames will be destroyed irrespective of DL Control.bit0 - due to a recent spec change source address shall be marked always. CRC will be modified, previously did blind forward for such frames	None

Dependencies

Refer to System Requirements section in AM335x Industrial SDK Getting Started Guide.
