Compiler/TMS320F28377D-EP: Flash API - Source files for the F021_API_F2837xD_FPU32.lib

Part Number: TMS320F28377D-EP
Other Parts Discussed in Thread: C2000WARE

Tool/software: TI C/C++ Compiler

I am looking for the Flash API files. I have the C2000Ware_1_00_06_00_Software. I am needing the source files for F021_API_F2837xD_FPU32.lib. How will I be able to get those?

How different are the Flash API routines between the F28335 Flash API and the F2837xD API? What differences would I see if were to use the Flash API for both F28377D- EP and F28379D processors?

Please advise.

Subha,

There should not be any difference in Flash API usage between F28377D-EP and F28379D (both devices support 1MB Flash).
Source can be shared with a NDA and an agreement. Contact your local FAE or us offline and we will provide you the details.

Regarding your question on Flash API difference between F28335 and F2837xD: Note that the prototypes of the Flash API functions are not same between these two devices. Flash technology and wrapper used are different between these two devices and hence the API is different.
For example, F2837xD Flash has ECC. This will require you to program a minimum of 64-bits (aligned on 64-bit boundary) at a time.

Please refer to F2837xD Flash API (V1.54) reference guide for more details : www.ti.com/.../spnu629
This wiki can help as well: processors.wiki.ti.com/.../C2000_Flash_FAQ
Also, refer to F2837xD TRM's "Flash and OTP Memory" chapter: www.ti.com/.../spruhm8h.pdf

Thanks and regards,
Vamsi

We are trying to port F28335 application to the F2837xD processor. Is there an example project or a tutorial ( other than the Flash API reference guide) that will help us through these Flash functions - Do's and Don'ts?

At this time we are looking to use only CPU1 but once we have the application built and tested for CPU1 , we will use both CPUs for further development.

Please advise.

Thanks,

Subha

Subha,

Please take a look at the example provided in C2000Ware at C2000Ware_1_xx_xx_xx\device_support\f2837xd\examples\dual\flash_programming.

Also, I would suggest to read through this wiki: http://processors.wiki.ti.com/index.php/C2000_Flash_FAQ#Flash_API_wiki

Once you go through the example, wiki and API guide, if you have any specific questions, please let me know.

Thanks and regards,

Vamsi

Thank you, I am working with my team to get the NDA going.

Though this is not directly related to my original question, it is related. How do I get the device driver library source files for both the F2837xD and F28335 devices. I actually have the F2837xD driver libraries here:

However I am unable to find the F28335 driver libraries. I need them for a study. Please advise how I can get access to them.

Thank you.

Never mind. Found them under C2000Ware_1_00_06_00_Software\device_support\f2833x\common\source.

Subha,

Image you copied is lost. May be you can mention the path.

F28335 device support files are in C2000Ware at \C2000Ware_1_xx_xx_xx\device_support\f2833x.

Is this the one that you are looking for?

If you have more questions on that, I would suggest you to open a new thread.

Thanks and regards,
Vamsi
