Other Parts Discussed in Thread: TMS570LS3137

Hello everybody,

Could anyone help me? I need to develop a bootloader to TMS470M06607. I read QJ Wang has developed one but I can not download the code source.

Thanks in advance!

Hello,

I have forwarded your question to QJ. I believe the bootloader used to be available on our Wiki page, but I don't know if it is still supported or not. QJ should be able to provide you the details of availability.

Hello,

As some additional information, there is a CAN based bootloader avaiable for the TMS470M devices. The download for this bootloader is located at:

http://processors.wiki.ti.com/index.php/Category:TMS470M#Tools_.26_Software

Although you have stated you would like an SCI bootloader, this one would have the framework you are looking for and you would simply need to replace the communication mechanism from CAN to SCI. We also have examples of an SCI bootloader for our TMS570 products located at :

http://processors.wiki.ti.com/index.php/Category:TMS570#Tools_.26_Software

This project could give you a good reference on how to integrate teh SCI portion into the TMS470M project.. Note that the TMS570 bootloader would use a different Flash API so it cannot be used directly.

Hi Chuck,

The links you gave in above post are not linked to a place with demo source code. Actually they are the links to TI wiki website which asking subscribers to contribute their source code. Are you sure those are correct links?

Could you please give this a follow up? Thank you!

Lisa

Hello Lisa,

I apologize the inconvenience. I am not certain why the links are not working for you. They do link to a wiki page but perhaps your view externally is different than my view internally at TI. It may be that these software packages have now been released through our official channels so they are no longer listed externally on the TI web.

None the less, the application note for the CAN bootloader for the TMS470M devices can be found at www.ti.com/.../spna200.pdf and the source zip file at www.ti.com/.../spna200.

With respect to the sci bootloader for the TMS570 devices, the following links are to the bootloaders for the TMS570LS3137 devices.
Application note: www.ti.com/.../spna199.pdf
Source: www.ti.com/.../spna199

Also note that other application notes on bootloaders can be found under the Hercules product pages for specific part numbers under the technical documents tab.

Lisa,

Also, just to be sure you are aware, the Flash technology, CAN module and architecture of the TMS470M devices are not compatible with the R1B1M device.

Hi Chuck,

I really appreciate your quick response! I have got the demo code you put here.

Yes, I know that TMS470M is different from SM470R1B1M.

Best regards,

Lisa
