Dear CASPERites, Thanks again for the very useful CASPER2019 workshop. I'm trying to build upon what I've learned there.
I have a ROACH2 board that I want to program and control with casperfpga.
Control is fine when I previously programmed the board through telnet.
But I get this kind of error when attempting to program it (bof or fpg):
> In [4]: fpga = casperfpga.CasperFpga(roach2)

I believed that my tcpborphserver could be too old (how to get the version,
btw?) for casperfpga (branch tutorial2019 at the time I installed it), even if
the Traceback is not exactly what is shown on
https://www.mail-archive.com/[email protected]/msg07451.html.
To check that hypothesis and try a newer tcpborphserver3, I started to setup
TFTP+DHCP+NFS using "ROACH-2 Production Test Machine Setup" documentation and
files from https://github.com/casper-astro/roach2_nfs_uboot. I merged
dnsmask.conf from those 2 sources and modified /etc/exports for my needs. You
can get a glimpse at my configuration here:
https://github.com/CedricDViou/NRT_2G_channelizer/blob/master/README.md
When netbooting, I got TFTP and DHCP to behave properly, but I get stuck when
mounting the file system from nfs (with or without nolock option):
> IP-Config: Got DHCP answer from 192.168.40.1, my address is 192.168.40.96
> IP-Config: Complete:
> device=eth0, addr=192.168.40.96, mask=255.255.255.0, gw=192.168.40.1
> host=roach2, domain=acme.pvt, nis-domain=(none)
> bootserver=192.168.40.1, rootserver=192.168.40.1,
> rootpath=/home/nfs/roach2/current,nolock
> nameserver0=192.168.40.1VFS: Mounted root (nfs filesystem) readonly on
> device 0:11.
> Freeing unused kernel memory: 144k freed
> nfs: server 192.168.40.1 not responding, still trying
> nfs: server 192.168.40.1 not responding, still trying
However, my server actually sees the request and grants it:
> Sep 4 12:22:17 nanunib rpc.mountd[25828]: authenticated mount request from
> roach2:713 for /home/nfs/roach2/squeeze_root.ppc (/home/nfs)
And when I try mounting the filesystem myself after a soloboot (just to test my
nfs server), I need to add the nolock option to have some success:
> / # mount 192.168.40.1:/home/nfs/roach2 /mnt
> svc: failed to register lockdv1 RPC service (errno 111).
> lockd_up: makesock failed, error=-111
> mount: mounting 192.168.40.1:/home/nfs/roach2 on /mnt failed: Connection
> refused
>
> / # mount -t nfs -o nolock 192.168.40.1:/home/nfs/roach2 /mnt
> / # ls mnt
> current squeeze_root.ppc
Any ideas about this problem?
When this works, I'll probably attempt upgrading the board (romfs at least, and
u-boot?, kernel?, all of them?) with:
https://casper.ssl.berkeley.edu/wiki/Getting_Started_with_ROACH2#ROACH2_kernel.2C_bootloader_and_romfs_upgrades
... if you think it's something I should do with my current configuration:
> U-Boot 2011.06-rc2-00000-g2694c9d-dirty (Dec 04 2013 - 20:58:06)
> Linux version 3.9.0-rc1+ (shanly@shanly-HP8710w) (gcc version 4.6.1 20110627
> (prerelease) (GCC) ) #8 Wed Mar 6 12:54:28 SAST 2013
> BusyBox v1.19.4 (2012-05-18 14:57:54 SAST)
Sincerely Yours,
Cedric
