TMS320C6747: Parallel nor flash

Part Number: TMS320C6747
Other Parts Discussed in Thread: OMAP-L137

Hi E2E,

Our customer needs your expertise with TMS320C6747 DSP. Here are the details of the query.

In TMS3230C6747 boot mode pins are set regarding nor flash parallel interface to EMIFA. Some of the address pins are connected to GPIO's which are pulled high. If we set pin multiplexing for boot mode pins and load the code through emulator then code stores in flash or else there is another procedure for loading the code in flash.

Is the file loaded in flash is in .out format or in another format? Is the flash code is loaded through xds100v2 emulator or another? I want the complete setup detail of flash code load.

Thank you for your guidance.

Regards,
Carlo

    Hello Carlo,

    Firstly, the application binary needs to be converted to AIS binary. Please refer to this app note for details: Using the TMS320C6747/45/43 Bootloader.

    Secondly, a flashing utility needs to be used to flash the application in AIS format to the NOR flash. Please download the flashing utility from here. After installation, you'll find the UART based flashing tool <flash tool root folder>\OMAP-L137\GNU\sfh_OMAP-L137.exe. Please refer to the attached document for how to use this tool. An alternative is CCS based flashing tool at <flash tool root folder>\OMAP-L137\CCS\NORWriter. Please follow instructions in the readme.

    Lastly, for custom board, you may need to rebuild the flashing tool. Please refer to the attached document as well for details.
