Introduction

StarterWare 02.00.00.04 provides no-OS platform support for Beaglebone which is based on TI AM335x SOC. StarterWare 02.00.00.04 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.

Supported Features

• User Bootloader for stand-alone booting of the board.
• Device Abstraction Layer (DAL) libraries for the following peripherals
  • Ethernet
  • DMTimer
  • EDMA
  • GPIO
  • High-Speed I2C (HSI2C)
  • Multi-channel SPI (McSPI)
  • High-Speed MMC/SD
  • Real-Time Clock (RTC)
  • UART
  • USB(CDC, Custom Bulk & MSC)
  • Watchdog Timer
• MMC/SD Library
• USB library
• APIs to configure Cache and MMU.
• Support for switching between Privileged and Non-Privileged modes.
• Support for both IRQ and FIQ handling

• Example applications for Beagle Bone Rev A3 to demonstrate
  • Ethernet
  • Timer
  • GPIO
  • High-Speed MMC/SD
  • RTC
  • UART
    • Using Interrupts
    • Using DMA
  • HSI2C
    • Using Interrupts
    • Using DMA
  • Watchdog Timer
  • Cache and MMU
  • USB in CDC device mode
  • USB in Custom Bulk device mode
  • USB in MSC device mode
  • An Out-Of-Box (OOB) application using multiple peripherals.

What is Not Supported

• Nesting of interrupts within host interrupts
  • One IRQ cannot pre-empt another IRQ
  • One FIQ cannot pre-empt another FIQ
• Security Extention Features
• Applications using standard malloc/calloc
  • StarterWare 02.00.00.04 Startup Code neither call any library nor initializes heap. Hence does not perform initializations required for malloc/calloc.
• Peripherals or features not mentioned as part of "What is Supported" section are not supported
• Downloading and debugging support for IAR Embedded Work Bench.

New in this Release

None

Fixed in this release

Issue Identifier	Issue Description	Issue Resolution
SDOCM00086491	TI binary image converter built for bootloader cannot be used for application binaries	Image converter modified to take load address and boot modes as parameters

Known Issues / Limitations

Issue Identifier	Issue Description	Workaround
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
SDOCM00084265	CPLD I2C: Communication with CPLD via I2C is not happening	CPLD contains information related to the profile settings. Instead of reading the profile setting from CPLD, hardcode the profile value in your code.
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.
SDOCM00086209	IAR and TMS470 Projects not created for few examples.	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.
