Dear Stephane,
netboot booted perfectly well.
the problem was due to a strange bug in my dt. (a clk setting)
ping was working but none of the services were!! (turned out i should not have been sure of net :)
which led to nbd-client getting time out. now it works fine.
thanks for all your help

Dear Stephane,Thanks for the detailed guide.I am sure of network because even during "nbd-client trying to connect..." I can ping the board from the host.tried the dhcp instead of static ip and result was the same.I will continue with nbd.debug.it gives me a prompt. on that prompt i cansee that i have the /dev/nbd0also i can ping the host. but nbd-client does not run (timeout)strange is that when I boot from normal sdcart nbd-client and connecting to host through that is working.the problem happens when booting from initramdisk.I will debug further and tell you where did i get.thanks again for the information.VahidOn Thu, Oct 10, 2019 at 1:09 PM Stephane Desneux <stephane.desneux@xxxxxxx> wrote:Hi Vahid,
This seems to be an issue with the network setup.
1) check the kernel command line
Can you dump the kernel command line arguments? (these are logged by the kernel
at the beginning: search for "Kernel command line" in kernel log). On a Renesas
(H3+KF) setup, I have this command line:
console=ttySC0,115200 ignore_loglevel vmalloc=384M video=HDMI-A-1:1920x1080-32@6
0 root=/dev/ram0 ramdisk_size=16384 ip=dhcp rw rootfstype=ext4 rootwait
rootdelay=2 nbd.server=10.0.0.11
'ip=dhcp' is the important parameter for netboot :) Note that you can also put
an IP address (dhcp server is not mandatory, but just convenient)
2) check if the kernel has initialized the first network interface correctly
If the command line is ok, do you see IP initialization later in the kernel log,
like this:
[ 5.129353] Micrel KSZ9031 Gigabit PHY e6800000.ethernet-ffffffff:00:
attached PHY driver [Micrel KSZ9031 Gigabit
PHY] (mii_bus:phy_addr=e6800000.ethernet-ffffffff:00, irq=236)
[ 8.331681] ravb e6800000.ethernet eth0: Link is Up - 1Gbps/Full - flow
control rx/tx
[ 8.354037] Sending DHCP requests ., OK
[ 8.373881] IP-Config: Got DHCP answer from 10.0.0.1, my address is 10.0.0.30
[ 8.381017] IP-Config: Complete:
[ 8.384246] device=eth0, hwaddr=2e:0a:0a:00:87:be, ipaddr=10.0.0.30,
mask=255.255.255.0, gw=10.0.0.1
[ 8.393811] host=h3ulcb, domain=homelan.sdx, nis-domain=(none)
[ 8.400076] bootserver=10.0.0.5, rootserver=10.0.0.5, rootpath=
nameserver0=10.0.0.1
3) investigate manually by using nbd.debug
If you want to debug the initramfs sequence (mounting nbd device etc.), you can
add nbd.debug=1 in the kernel command line (in uboot AFAICS). This will set some
breakpoints in the initramfs script and will give you a shell prompt: you can
then investigate further manually.
Hope this helps!
