Hi Denis, Yes, the Host-Target-Interface (HTIF) has been refactored/removed in RISC-V. Also, it was meant to work with riscv front-end server (riscv-fesvr) which is not the case for your HiFive BSP I guess.
I believe now it's the good time for you to start creating your own HiFive BSP. You'll have to read/know how to output data over the HiFive serial port or so, and develop your own console driver for the board. You might find this link useful [1] when creating a new BSP, and also use other BSPs as a reference (e.g. riscv_generic). Main things to be aware of when creating a new BSP are: 1) startup code, 2) console driver, and 3) timer driver. To make things easier for you, and to give you credit for your contributions when merged upstream, you'd want to create a new branch for your HiFive BSP based on priv-1.10, and rebase against it when/if I make changes to it. Keep the good work up.
