AM335x SYSBIOS Industrial SDK 01.01.00.08 Release Notes

Mar 26, 2015

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.

Known Issues And Limitations

Issue Identifier	Issue Description	Workaround
SDOCM00092510	EtherCAT: Multiple FMMU access in a single datagram to a slave for process data using LRD/LWR commands	Use LRW instead of LRD/LWR
SDOCM00098105	EtherCAT: PDI/PD watchdog counter incremented by 1 whenever PDI/PD watchdog is disabled	None
SDOCM00098950	EtherCAT:LRD access on unused registers increment WKC - no register protection while using LRD	None
SDOCM00103424	CPSW driver does not work in 10Mbps mode on ICEV2	None
SDOCM00105048	EtherCAT: LRW access to non-interleaved input and output process data of multiple slaves does not work. SOEM accesses slaves in LRW mode this way	Use LRD/LWR for process data access or use more optimal interleaved access for process data access from Master (TwinCAT way)
SDOCM00105257	On ICEV2, Ethernet/IP application in CPSW mode doesn't connect with EIP Tool. (This is found to be problem with i2c communication to clock synthesizer which proivde clock to RMII ports)	Increase delay in between i2c operations by setting Task_sleep as the delay function. This fix is already available SDK.
SDOCM00108541	EtherCAT: Rx Time Port1 (0x904) time stamping not done correctly when write to 0x900 is done cyclically
SDOCM00113028	EtherCAT: Link/Act LED behavior on ICE v2.1 is not compliant to ETG1300(Indication & Labeling spec)	Enable SW strapping (h/w mod)for TLK110 to override Link LED behavior to blink on activity
SDOCM00113092	Ethernet/IP: Successful auto-negotiation reported in Interface flag attribute (attr 2) of Ethernet Link Object when testing PC is in forced mode	None
SDOCM00118052	PROFINET: Redundant PROFINET RT binary header files (profinet_rt_PRU0/1_bin.h) in SDK.	Driver uses the right header files unless older version of "iPNDrv.c" is being used. Please make sure "profinet_irt_PRU0/1_bin.h" are being used.
SDOCM00113093	Ethernet/IP: DLR: Ethernet/IP application does not support DLR Flush table frame	None
