F021FLASHAPI: Aerospace Qualification of the F021 API

Part Number: F021FLASHAPI

My team is developing software for the TMS570LC43X processor, supporting an aircraft manufacturer. All software needs to be developed following civil aerospace guidance (RTCA DO-178C). One of the function we are developing requires saving data on the micro-controller internal flash. Reviewing available discussions and past support request (see here and here ), we came to the conclusion that developing our own source code for the flash driver was not an option (TI does not support that options and require user to the F021 flash API an associated binary).
This request is to:

  1. Confirm the above statement (essentially that the F021 driver is our only option)?

  2. Assuming the answer to the above statement is yes, and that no DO-178C life-cycle data is available for the F021, we will need to develop some data (requirement, tests...) to support the qualification of the F021. We understand that, under NDA, we can audit the source code, which would probably help with the lifecycle data development, and help us estimate the effort. We would therefore like to set this in motion
