Re: [BUG] TFTP: No access to subdirectories

[Franz Forstmayr <f.forstmayr@gmail.com>]

Hi,

I just saw this old thread and wanted to ask, if this one has been
fixed already? I just ran into a similar/same problem using
barebox-2018-04 from the  phytec repository
(https://git.phytec.de/barebox/log/?h=v2018.04.0-phy).

When i want to boot net the first time, it fails the second time successes.

barebox@Phytec phyCORE-i.MX6 Ultra Lite SOM:/ boot
booting 'net'
eth0: 100Mbps full duplex link detected
T open: Invalid argument
could not open /mnt/tftp/segin1/Image: Invalid argument
Booting 'net' failed: Invalid argument
booting 'net' failed: Invalid argument
boot: Invalid argument
barebox@Phytec phyCORE-i.MX6 Ultra Lite SOM:/ boot
booting 'net'

This is my /env/boot/net/

#!/bin/sh

[ -e /env/config-expansions ] && /env/config-expansions

path="/mnt/tftp/${global.hostname}"

global.bootm.image="${path}/Image"
global.bootm.oftree="${path}/oftree"

nfsroot="${nv.net.server}:/nfs/${global.hostname}"
global.linux.bootargs.base="ip=$nv.dev.eth0.ipaddr:$nv.net.server:$nv.net.gateway:$nv.dev.eth0.netmask::eth0:off"
global.linux.bootargs.dyn.root="root=/dev/nfs nfsroot=${nfsroot},vers=3"

My workaround is, to set up an md5sum global.bootm.oftree and for some
strange reason, the boot command successes.
Any thoughts?

Regards
Franz

Thanks for the info, Antony!

I must admit that I was only searching the mailing list archive for the
subject concerning "bug" or "tftp", but not the content of the residual
mails before I wrote my bug report.

Good to see that you've already found that commits that cause the
problem. Hopefully it will be fixed in one of the next releases.

Best regards,
Dennis Menschel
