Untethered lowRISC: run bbl using Verilator
by Grady Chen
Hi All,
For some reason, I am running bbl using Verilator.
The following are my steps:
grady@riscv:~/lowrisc-chip/riscv-tools/riscv-pk$ elf2hex 16 8192 build/bbl
> ../../vsim/bbl.hex
grady@riscv:~/lowrisc-chip/vsim$ ./DefaultConfig-sim-debug +vcd
+vcd_name=bbl.vcd +max-cycles=100000000 +load=bbl.hex | spike-dasm > bbl.log
Core 0 get unsolved tohost code 8cb0 *# This is what I expected.*
grady@riscv:~/untether/lowrisc-chip/vsim$ grep request bbl.log
memory read request: 1 @ 200
memory read request: 1 @ 240
memory read request: 1 @ 280
memory read request: 1 @ 2c80
memory read request: 1 @ be80
memory read request: 2 @ bfc0
memory read request: 1 @ 2cc0
memory read request: 1 @ 2d00
......
There is only the memory read request but no memory write request. Seems
not right.
Any one know how to make SD assembly instruction leads memory write
transaction?

lists.lowrisc.org has problems with SPF (I think)
by Ludovic Pouzenc
Hi,
(sorry for anoying all the list, but suggested
mailman(a)listmaster.pepperfish.net does not work)
I just received an automated unsubscribe mail from the lowrisc-dev list
after many (unnoticied) bounces. My mail server says that SPF checks
against lists.lowrisc.org fails. I try to figure out things manually and
I think there is a missing ipv4 or cname in your SPF string about "bagpuss".

^------ this one goes in "-all" I think.
I just renew my subscription, so if there is activity on the list, you
should find rejects from mail.pouzenc.fr [185.61.116.42] in your logs if
the problem persists. It does not have IPv6 connectivity yet, sorry.
Be aware that SPF could eat a reply to this email too :o)
Cheers,
