Sorry to hear that you're feeling dejected.

On your questions: 1) We are providing FE310 samples to folks who ask us for them at info@sifive.com

See our past forum posts for similar requests: https://forums.sifive.com/t/assistance-getting-in-contact-wi... https://forums.sifive.com/t/e300-on-the-market-other-sbc-s-w...

2) We do provide both versions, just as you recommended. SiFive continues to maintain the Rocket repository at https://github.com/freechipsproject/rocket-chip

We intend to continue to maintain this core and ensure it's compatible with any updates to the RISC-V specification.

For commercial customers who do not want to utilize rocket-chip, we are providing them with other options.
