Introduction

StarterWare 02.00.00.05 provides no-OS platform support for TI AM335x GP EVM and Beaglebone which are based on TI AM335x SOC. StarterWare 02.00.00.05 provides Device Abstraction Layer, libraries, peripheral/board level sample/demo examples that demonstrate the capabilities of the peripherals of AM335x. StarterWare comes with pre-compiled binaries for bootloader and example applications which can be run from an SD card.

Fixed in this release

Issue Identifier Issue Description Issue Resolution
SDOCM00084265 CPLD I2C: Communication with CPLD via I2C is not happening Issue is resolved in Beta version of TI AM335x EVM 
SDOCM00086209 IAR and TMS470 projects are not created for a few examples IAR and TMS470 projects are created for Power Management and USB examples
SDOCM00086796 Interrupt status clearing API of HSI2C DAL fails to clear RAW interrupt status.  
Used write to clear instead of read modify write to clear RAW status.

Known Issues / Limitations

Issue Identifier Issue Description Workaround
SDOCM00087753 USB MSC Dev Mode executable doesnot work in standalone mode. However the .out file works when loaded from CCS. The command file for CCS can be modified (Line 57:".bss  : load > DDR_MEM" to be changed to ".bss  : type = NOLOAD,")and the project can be rebuilt. The updated command file usb_dev_msc.cmd (for EVM and beaglebone) is available in this link
SDOCM00084262 UART: UART EDMA example application is not working in FIFO Enabled mode. The issue is under investigation. In case of UART EDMA, disable FIFO.
SDOCM00084263 McSPI: McSPI is not working at 48MHz, eventhough the flash and the McSPI controller supports operation at 48MHz The frequency of operation can be kept at 24MHz for SPI Flash access
SDOCM00085661 UART EDMA example not working consistently with AM335X EVM and Beagle Bone None
SDOCM00085925 Cache MMU Example application does not work consistently in AM335x EVM and Beagle Bone None
SDOCM00086247 INF file required to support the USB CDC serial device on WIN 7 64 bit host. None.
SDOCM00086202 Hardware register layer files of peripherals which are not part of AM335x SOC are included in the Starterware release package. None.
SDOCM00086275 Spurious interrupts generation can happen sometimes and generate an abort and halt the execution. Dummy ISR is added to handled spurious interrupt to demo application. This can be done in any application to prevent spurious interrupt generation from halting the execution.
SDOCM00086180 Starterware web server takes a long time to start sometimes. Several options in lwipopts.h file can be changed and fine tuned
SDOCM00086319 Beagle Bone Demo application home web page is not coming consistently, when tested across networks Several options in lwipopts.h file can be changed and fine tuned
SDOCM00086320 The software implementation of CLZ, NumLeadingZeros() in grlib/string.c, misses a special case: the case of being passed a zero. Update the code to add a check that, if the parameter passed is zero, return 32.
SDOCM00086390 Unable to load .out file from IAR IDE. None
  • If the code sourcery installation path contains white spaces, Cygwin may give errors while linking.
