CCS/TMS320C28346: Can CCS/Uniflash be customized to flash a parallel on-board flash device

Jim Schierenberg

Part Number: TMS320C28346
Other Parts Discussed in Thread: UNIFLASH,

Tool/software: Code Composer Studio

We have a board with the TMS320C28346 and a Cypress S29AL016J parallel flash device. In the past, as a separate tool, SDIflash could be customized to program an on-board flash device. Now that SDIflash is part of CCS or Uniflash, is there a similar way to customize Uniflash to program our on-board flash? If so, could you elaborate on the steps, or point me to a document that describes the customization process?

Thanks.

That document is about 11 years old and refers to things that appear not to exist in CCS 901. Such as SDFlash.exe.

Hi Jim,

I could not find anything newer than than the doc / tool Manoj mentioned. I believe that is the most relevant collateral for interfacing with external memory on the C2834x device, which is a relatively old C2000 device in itself.

You may need to use an older version of CCS to use the SD flash tool if newer CCS version do not support it.

Best,

Kevin

The above did not resolve my problem, as I felt the "older version" approach could be a rabbit hole.

But, it did cause me to flip to the Debug Server Scripting (DSS) scripting interface to automate execution of a .out file we created that is able to read files from the operating system and program them into external flash.
