As long as issue#65 isn't fixed opensbi is mostly a no-go for me. At least it
gives me more reasons to press the reset button. :-)
The reset button works fine for me an Atish. I am sure it works fine for lot of
other folks too.
BTW, as-per discussion with SiFive folks the reset button on Unleashed
Board is not much tested and it can misbehave on certain boards. It is quite
possible that you might have a "flaky" board.
I don't think the reset button differs between boards. As far as I know, the
issues are really just that it doesn't reset everything -- specifically some of
the IP on the chip (clock, power, JTAG) isn't reset and nothing on the board
(SD, ethernet, PCIe, etc) is reset. This frequently results in flakiness when
debugging drivers, but the cores and memory system should all be OK.
Is that issue 65 on github.com/opensbi? If so it clearly says this isn't a
reset button issue.
