In our F28027 uses kernel A for programming, It programs all 4 FLASH segments: A, B, C, D. I would like to program only FLASH segment C. How to do it?

The documentation mentiones that the kernel A is for TMS320F28027, but it does program all segments together.

Kernel B, accoridng to documentation, can program FLASH segment individually, but it seems that it cannot be used with TMS320F28027.

This has to be done in the field, without JTAG, from another processor, and it already wors for all four segments.

It seems to be feasable, since the TI UniFlash tool can program individual FLASH segments, A, B, C, D.

Please, advise me how to field-program TMS320F28027 FLASH, only segment C, or only segments A, B, D with the flash kernel of TI without JTAG.

Vlad,

Yes, this would certainly be doable, I am attaching a screenshot of where you would make the change in the Flash kernel. Please try this and let me know if it works. At the moment, we are erasing all the sectors - try picking which one(s) you want to erase and rebuild the Flash kernel.

Thanks,

Sira

Thanks Sira,

It makes sense. We will try it, and put more flexibility in our changed kernel, as you pointed out.

regards,

Vlad
