Hi Liang Yu,
Whether the processor is EOL (End of Life) or not does not matter in my understanding.
The obligation to provide information arises from the use of the respective license. The customer has been using the FPGA unchanged with the Nios II for 10 years. The FPGA is also not EOL. Therefore, with every FPGA purchased, they bring the binaries generated with the tooling to the market.
Now their customers are interested in actually demanding FOSS (Free and Open Source Software) information due to the CRA (Cyber Resilience Act). If this cannot be clarified technically (i.e., via the RD), it will likely come back to them through Legal in another area. At least I have noticed: Previously, customers did not care. Now, their Product Management is being confronted with corresponding inquiries.
What can we do to get them the answers they need?
Br,
