ysionneau: i worked as a contractor in network security and log analisys projetcs projects (install, deploy, setup, support integrate)
<kristianpaul>
ysionneau: new one is about system administration on a network security company (alertlogic)
<kristianpaul>
wpwrak: i dint have to work? well not all time but i have too :)
<kristianpaul>
wpwrak: new one have better conditions, of course more responsabillity
<kristianpaul>
wpwrak: new city
<kristianpaul>
well i always worked here but not sleeping/living
<kristianpaul>
wpwrak: and when i have to, usually was something to deliver faster plus other represed work
<wpwrak>
(not having to work) i remember those times where you were working on gps all the time, with the occasional day, maybe once per week, when you said you had to do something for your company. it did sound rather relaxed ;-)
<kristianpaul>
wpwrak: also improve because i'll use english all time, bigger team
<wpwrak>
development work ?
<kristianpaul>
integration
<kristianpaul>
but not fully focused on development as a developer :)
<wpwrak>
ah, where the bugs of team A and B meet ;-)
<kristianpaul>
lol
<kristianpaul>
kinda
<kristianpaul>
relaxed, yes it is, but as i said sometime things get represed
<kristianpaul>
and when i was working in gps, i just have to work 3 days per week :D
<wpwrak>
aah, i see
<wpwrak>
(pressed) sort of like the fire police :)
<kristianpaul>
yeap
<kristianpaul>
the good think is that now i can save money to travel to a ccc3 or similar event
<kristianpaul>
btw are you working right now wpwrak ?
<wpwrak>
yeah, on an embedded ieee 802.15.4 project
<kristianpaul>
i meant paid work
<kristianpaul>
ahhh
<kristianpaul>
good :)
<kristianpaul>
you said embedded and came to mind first the password keeper thing
<wpwrak>
naw, the password safe is unpaid fun.
<larsc>
besides the money from the NSA
<wpwrak>
you can't prove that the account belongs to me :)
<larsc>
I don't have to

ysionneau: btw you can debug the gdb with "set debug remote on" (or sth like that)
<mwalle>
no need to trace with wireshark
<mwalle>
ysionneau: i guess qemu singlestepping with mmu is broken :)
<ysionneau>
yeah I put a breakpoint in the tlb miss handler
<ysionneau>
and it works better
<ysionneau>
better than single stepping :)
<ysionneau>
18:23 < mwalle> ysionneau: btw you can debug the gdb with "set debug remote on" (or sth like that) < ah good thanks :)
<ysionneau>
qemu is such a useful tool
<ysionneau>
thank you so much for the lm32/milkymist work on qemu :)
<ysionneau>
that's very useful for development
<mwalle>
np ;)
<mwalle>
ysionneau: could you send me your binary, so i could have a look at the single stepping?
<mwalle>
larsc: are you at home? :)
<ysionneau>
mwalle: yeah sure!
<ysionneau>
I think it can be triggered by just writting 0d74 to PSW and nop nop nop nop
<ysionneau>
just to trigger a tlb miss exception
<ysionneau>
anyway I will send you the binary ;)
<ysionneau>
gotta go, see you
<mwalle>
bye
<mwalle>
ysionneau: are you sure you're single stepping (si command in gdb)? because i can single step through the whole mmu unit test without any lockups

mwalle: I think I was doing nexti
<ysionneau>
wait a minute
<ysionneau>
mwalle: hum weird, it seems the problem disappeared
<ysionneau>
hum well
<ysionneau>
not really
<ysionneau>
GDB does not hang but it goes another round (my tlb miss and fault handler are nops)
<ysionneau>
one would expect GDB to single step to the first instruction of the exception handler
<ysionneau>
instead, it goes through the exception handler and to crt0 and back to the main code and then stops on the first breakpoint it encounters -> right before wcsr to PSW
<ysionneau>
maybe I should just send you the binary :)
<ysionneau>
oh, with stepi indeed it works as expected, it stops at the exception handler
<ysionneau>
it was just my understanding of stepi / nexti which was wrong :$
<ysionneau>
sorry for the false alarm

Question for De0 nano owners: is the USB blaster thing recognized by Linux as a ttyUSB* UART?
<ysionneau>
or is this only for programming the device and not to get uart from milkymist-ng soc
<ysionneau>
hum ok a quich look at mibuild file for de0nano says it's using GPIO pins for uart
<ysionneau>
so no uart through the usb blaster
<ysionneau>
so I guess you need a TTL 3V3->RS232 converter
Russ has quit [Ping timeout: 240 seconds]
<ysionneau>
mwalle: good, I get the correct value in PSW, TLBVADDR and TLBBADVADDR in gdb when doing "info all-reg" after the tlb miss exception

mwalle: ah right, sorry forgot about you. I'm in Romania right now, so not at home
