When you build your bitstream, does it pass timing?
Other than that, doublecheck the register addresses in DTS?
That's all I can think of, off the top of my head...

2 years ago I was able to build bitstream with the following messages:

2 years ago I can make it work now.
I'm not sure this is the root cause, but from the message remote fence extension is not available in SBI v0.1, I guest the issue may from SB1 v1.0.
Enable this option on kernel make the linux boot ok

I'm not really sure how enabling RISCV_SBI_V01 in your kernel is in any way related to the dev board, fpga model, or HDL compiler you're using!
Seems like something about how you compiled the rest of your software stack (i.e., busybox or whatever it is you're booting on top of Linux).
Besides, the help line in the kernel Kconfig says RISCV_SBI_V01 is being deprecated, so relying on it is not a good long-term strategy.
But good to hear it's working for you, at least! :)

2 years ago The HDL compilation was ok and not related to kernel. The fpga bitstream was loaded to the board successfully without nay issue. I was having issue on booting boot.bin. If boot.bin that was built without RISCV_SBI_V01, then the booting is hang. And you are right, RISCV_SBI_V01 is being deprecated. I need to figure out the real issue that make the boot process hang.

2 years ago Thanks @lapnd I recently tried recompiling the kernel and I ran into the same issue.
For me it would hang after Timer extension is not available in SBI v0.1.
Adding CONFIG_RISCV_SBI_V01=y to the defconfig like you suggested did the trick.
Hello, I'm trying with Altera DE2-115 kit. I have added ethernet patch to make TFTP boot work. However, the booting is hang at step
