ApertusWeb0: hello gabe!

who is this?

then try /whois Bertl

ok great

I was just going to try and get everything setup to boot off tftp

excellent! and how is your progress/status?

I had a question though

no, but I started with it

ok

which made me assume some sort of linux build on there already

the bootp/dhcp and tftp have to run on some kind of server/pc

right

I assume the dhcp connection can come from my router though?

so after the zedboard gets an ip from the router with DHCP the bootloader requests the ip of the tftp server from the router? I plan on setting up tftp on my ubuntu development box

and yes, it then takes the information returned to request scripts and images via tftp

i'll have to see if it supports that

it will then send out the bootp requests automatically which should help you to test and configure the router

(this is the latest boot.bin atm)

dmj_nova1: promised me to put the 'reset environment' commands somewhere on the wiki, but I don't see them there, so give me a minute to dig them out

you just need to interrupt the autoboot, and issue:

saveenv

that should configure u-boot properly after boot.bin was updated

it's a file not an image actually, so just copy it there (and remove the existing one)

ah. ok yeah I just realized when I plugged it in that it's a file

no, just the first time, the environment is stored in the board

I have the zed-boot prompt

ok. what's the easiest way to check if it got an ip from the router? it appears I can't use usual linux commands like ifconfig

the first line you should look out for (in u-boot) is this one:

well, actually you get another one earlier:

(both will tell you that your boot.bin is up-to-date and working as expected)

then something like this:

BOOTP broadcast 1

okay. yes I see that now

after typing the "reset" command to see it cleanly

(with your IPs of course)

will their be an indication if it got an ip address but no IP for the TFTP server? it says the link is at 100 mbps and it keeps trying the broadcast, with no indication if it got an IP

ok

yeah, that sounds good

maybe even use a GBit network card/port on your machine as the zedboard has gigabit

nah, shouldn't be a problem

good to know

hmm, how does virtual box come into play?

ah, okay :)

have you used the ISC DHCP server?

do you have to enter the mac address for the zedboard ethernet? the examples I see indicate that

yes

(i.e. as mac blabla requesting ...)

that makes sense

where the ZED folder is in my tftp folder

ok

you also want to specify a 'next-server' which is the TFTP server

I was able to resolve the tftp file not found issue. i'm a bit further, but I'll have to resume later. right now it states "a panic occurred, switching back to text console"

well, sounds good, I presume the panic happens in the booted linux kernel, yes?

so maybe you are booting with the wrong device tree, in any case, the tftp boot part should be fine if you get that far

just upload the entire bootup log when you find the time and let me know (pastebin)

great thanks. I appreciate all the help!

I'm using the ZED.zip from here: https://github.com/apertus-open-source-cinema/alpha-hardware/tree/master/Zedboard-Files/TFTP-booting

might already be a little outdated, but it should boot

morning everyone!

need to go to the supermarket

back

dmj_nova1: hmm, not sure I already mentioned it, but the PMOD debug is now shared on OSHPARK, so on http://oshpark.com/shared_projects/page/3 you should find it after a search for apertus (or on the next page)

if you still want to try to solder it yourself, simply order a pack and let me know, I send you the details for the parts
