TMS570LS1224: F021 Flash API validation

Tomas Kirchner

Part Number: TMS570LS1224

Hello,

We are using TMS570LS1224 as a control CPU in avionics under DO-178C (DAL-A) norm. We are obligated to verify 100 percent code coverage, decision coverage, etc. We also need to erase / program flash. F021 Flash API library is therefore required.

I would like to politely ask TI for help. We either need to get all tests-needed verification documentation of the library or to see the library source code to do the tests ourselves. Another possibility is to get datasheet to program all code needed. Is anything of these options possible?

With regards,

Tomas

Hello Tom,

TI does not normally distribute the source code. The reason for this is modifying the code can potentially impact the flash in the devices. A modified API must not be used in an application. For creating a flash programming solution, the flash API library must be used as provided by TI.

In situations where the user has a justifiable and legitimate need for the source code for certification purposes, it can be provided under a signed license agreement with TI.

The datasheet parameters are not supported for any modification to the source code.
