somlo: I am getting closer. Your patches were extremely useful :)

I am using UART_POLL than interrupt. I modified the dts accordingly by getting rid of interrupts. @somlo: Is there anything that comes to your mind that requires some changes in your patches? I am debugging the current problem using simulator now and hope to figure out the bug(s) soon.

scanakci: does BlackParrot have Supervisor and User mode support?
<scanakci>
yes

_florent_: litedram 48c2fc2 fixed the problem I had yesterday, we're back in business -- thanks!

scanakci: it'd be interesting if you could figure out what the trapping opcode is, and where... I remember seeing something like that when I tried booting linux on a rocket compiled without S, U, and a MMU
<somlo>
but that was long ago. How to fix it depends on what is breaking,and I can't tell off the top of my head from your screenshot
<scanakci>
true, I am collecting more debug info now. I should have a better idea in couple of hours.
<scanakci>
If I simulate the same bbl rather than pushing to the FPGA, it prints "[" (the first char of linux bootup) and hangs
<scanakci>
I hope fixing the issue when simulating will make it work on FPGA
