Re: [microblaze-uclinux] Ctrl-C does not work in shell

I have the same problem not being able to stop apps using CRL-C and such key combinations.

I'm having a problem right now mounting an NFS share on uClinux-2.4.32-uc0 on Microblaze. (followed Jason Wu tutorial for setting up on an ML401)

When I try to mount the share (which can be NFS mounted by other machines on the network), it fails saying the server is not responding, still trying.  The problem is it doesn't ever return to the shell prompt.  I suppose it's possible the system has simply crashed and is not accepting input.  But I've also had the problem when I first tried using ping from the uClinux shell... and there was no escaping it  It's quite a bit of time to have to redownload the kernel image again.

Does anyone out there no whether this is a terminal setup(ie hyperterminal or CRT) or a kernel setup issue?

Hi All,

I am using the Suzaku-S board from Atmark Techno, and I am just now
trying to shift from the 20040408 version of uClinux-dist that I got
from Atmark Techno to the CVS version of uClinux. I am able to compile
the system and it boots. Networking seems to work. But I have noticed
two problems so far:

1) Whenever I run 'hostname' (e.g. in the rc scripts) it never returns
to the shell.

2) Whenever I run any application that doesn't terminate itself,
CTRL-C won't kill it! For example, I can run ifconfig to set the IP
address, and then I can run ping and sucessfully ping a remote host,
but then I can't kill the ping app. Ctrl-C, Ctrl-Z, nothing I can find
has any effect.

Any ideas on what might be causing this? I am selecting the SUZAKU
platform in make menuconfig and I have left all the user application
data (shell, etc.) to the defaults.

As an aside, when I select the SUZAKU platform, all of the RC scripts
in the romfs are made non-executable. This prevents them from running
at boot. I can change these, but I think that the default behaviour
should be for them to be made executable when the romfs directory is
built (e.g. make romfs, or just 'make'), and this might be a bug in
the SUZAKU build config. I don't completely understand all of the
configuration that is done in uClinux.

-Jeff
