TI Information – Selective Disclosure

StarterWare – Development Tools

• Code Composer Studio (CCS)

• Integrated development environment for TI embedded processors

– Includes debugger, compiler, editor, simulator, OS…

– The IDE is built on the Eclipse open source software framework

– Extended by TI to support device capabilities

• CCSv5 is based on “off the shelf” Eclipse

– Going forward CCS will use unmodified versions of Eclipse

• TI contributes changes directly to the open source community

– Drop in Eclipse plug-ins from other vendors or take TI tools and drop them into an

existing Eclipse environment

– Users can take advantage of all the latest improvements in Eclipse

• Integrate additional tools

– OS application development tools (Linux, Android…)

– Code analysis, source control…

• Low cost!

StarterWare - Running examples within CCS

StarterWare includes GEL scripts to perform bootloader initialisations and

application loading within your IDE using a JTAG emulator

Application Code &

StarterWare - Bootloader Utility

• Acts as bridge between

RBL and application

• Applies same EMIF, PLL

settings as GEL file

• Use host PC tools to

prepare boot image:

– AISgen

– out2rprc

– Serial flash tool (SFH)

• Boot your application

quickly from SPI Flash

Beagebone Flashing And Booting – SD Card • Simple two step process

– Prepare SD Card

• The SD card needs to be prepared, by FAT formatting it as follows.

• Choose a SD card and a USB based or similar SD card reader/writer. Plug it to a

Windows host system.

• The converted bootloader binary has to be renamed to "MLO" and the application

binary has to be renamed to "app".

• Run the TI_SDCard_boot_utility_v1_0.exe executable (which is in release

package in the following directory - tools/sd_format/).

– Select the SD Card drive name, location of bootloader file (MLO) and

application image (app) path.

• Safely eject/remove the card from the host, unplug the card reader, remove the

SD card. The SD card is ready for use on the target.

– Booting the BeagleBone

• Insert the SD card into the SD slot

• Connect to the Virtual serial Port on PC (115200, 8, N, 1)

• On power on, the MLO is first detected and copied and executed from the OCMC0

RAM. The MLO then copies the application image (app) from the card to the DDR

and passes the control to the application. On Successful boot, following messages

appear on the serial console.

Beaglebone Boot with StarterWare

ROM

Bootloader

(RBL)

On-chip RAM

Bootloader

StarterWare

Application

On Power-up execution begins from on-chip ROM which:

1. Checks the boot setting (configured by DIP switches)

2. Loads the secondary bootloader from the respective

medium to on-chip RAM

3. Hands over control to the on-chip RAM

The secondary bootloader then:

1. Initialises PLLs

2. Enables Peripheral Clocks

3. Initialises DDR

4. Sets the operating frequency (up to 720 MHz)

5. Loads the application from respective medium to off-

chip DDR

6. Hands over control to DDR

The StarterWare Application code is then executed from DDR

DEMONSTRATION

37

StarterWare - Demonstration

• Import a CCS Project from

the StarterWare Release

package

• Build the CCS Project

• Create the Target

Configuration

• Launch and Debug project

Performance optimisation (1) –

Enabling the ARM VFP with Starterware • The AM335x Cortex A8 family feature the ARM VFPv3 Vector Floating Point

co-processor:

– Provides a significant performance boost for floating point arithmetic heavy

applications

– This is not enabled by default!

• Starterware build options, libraries and initialisation code require some simple

changes

– Initialise and enable the VFP and NEON sub-system in init.asm

(..\AM335X_StarterWare_02_00_00_06\system_config\armv7a\cgt\init.asm)

– Insert the following code before Clear_Bss_Section:

; Initialize NEON and VFP MRC p15, #0, r3, c1, c0, #2 ; Read CPACR ORR r3, r3, #0x00F00000 ; Enable access to CP10 and CP11 MCR p15, #0, r3, c1, c0, #2 ; Write CPACR ; Enable NEON and VFP MOV r0, #0x40000000 VMSR FPEXC, r0 VMRS R1, FPSID

Performance optimisation (2) –

Rebuild Libraries with ARM VFP Support • To make use of the VFP the support libraries and your application code all need

to be re-built with the ARMv3 options (check the <project>.cmd build file to

see the library dependencies ) :

– Platform, Drivers, System, Utils

– In the project settings select Runtime support library rtsv7A8_A_le_v3_eabi.lib

and float_support option VFPv3 then Clean and Build all dependent projects
