AM335x SYSBIOS Industrial SDK 01.01.00.04 Release Notes



Feb 26, 2013

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.

SDOCM00106811 EtherCAT: Unable to go to OP state with SYNC1 enabled (DC mode) - appeared after applying SSC5.10 bugfix posted in EtherCAT forums Fixed
SDOCM00106812 EtherCAT: SM Watchdog status reads "expired" when no output process data is configured Fixed
SDOCM00105819 PROFIBUS: Only the first 128 bytes of slave's response reaches PROFIBUS master during input change Fixed
SDOCM00106780 PROFIBUS: Using any value between 0 and 31 as PRU EDMA channel does not work, except for specific channel no's E.g.:- 3 Fixed
SDOCM00106260 Bootloader: SPI Bootloader crash due to stack corruption, causing JTAG connectivity issues on ICEv2 Fixed

Known Issues And Limitations

Issue Identifier Issue Description Workaround
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
SDOCM00097012 EtherCAT: SYNC0 jitter varies with distance of slave from reference None
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
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)
SDOCM00103424 CPSW driver does not work in 10Mbps mode None
NA Ethernet/IP: Two errors during TCP/IP interface test in CTT V 10 CTT limitation.
SDOCM00106802 Ethernet/IP: Seven errors during DLR Object test in CTT V 10 None
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.
