Network Problem on Skyeye running uClinux

[jeffrey....@gmail.com]

Hi everybody,

I want to run uClinux on Skyeye on my Ubuntu System.

Therefore, I followed the instructions on http://sourceforge.net/apps/trac/skyeye/wiki/uClinux.

The good news: uClinux on Skyeye 1.2.5 under Ubuntu 12.10 runs, if (all) the network-related lines in the skyeye.config file are commented (i.e., there is no network module present). I can run uClinux, add own applications, etc.

The bad news: When I uncomment the network line (net: type=rtl8019, mac= ...) in the skyeye.config file, the following error message occurs:

failed to setup_module (name:net, type:rtl8019)
*** stack smashing detected ***: skyeye terminated

(for detailed output, see below, modifying the skyeye.config file to "type:cs8900a" doesn't help, still the same problem)

Apparently, there seems to be a problem with the network module. I also tried to use Skyeye version 1.3.4-rc1, basically the same thing happens.

Searching on Google for the same error message ("failed to setup_module (name:net, type:rtl8019)") gave me the following 2 hits, though the problems don't seem to be exactly the same:

https://groups.google.com/forum/#!topic/skyeye-simulator/xmf6U1FQFOw
-> didn't really help

http://sourceforge.net/p/skyeye/bugs/32/
-> says that issue is fixed in Skyeye 1.2.8, but as I mentioned, I have the same problem in Skyeye version 1.3.4-rc1.


Some details on the software that I use:

Host System is Ubuntu 12.10
Skyeye version 1.2.5 (I installed the official Ubuntu package over apt-get)
GCC: from arm-linux-tools-20061213.tar.gz -> gcc version 3.4.4
uClinux -> uClinux-dist-20070130, basic configuration:
 Vendor         : (GDB)
 Product        : (ARMulator)
 Kernel Version : (linux-2.6.x)
 Libc Version   : (uClibc)

If you need more info on anything, just let me know.

Again, it seems to me that the problem is somewhere in the networking setup (which is bad, since basically the only thing I really need in uClinux is just that).

Anybody having any thoughts on that? Thanks in advance!

Jeff

Hi,
thanks for your response.

Strange. When I start skyeye as su, I get the following output:

There's no more
"failed to setup_module (name:net, type:rtl8019)" and
"tapif_init: icotl TUNSETIFF errorAborted (core dumped)",
but all the other lines are almost the same, just some addresses in the 'Backtrace' and 'Memory Map' have changed.

And still, Skyeye starts running uClinux without problems when I remove the networking line in the skyeye.config file.

For Skyeye 1.3.4-rc1, the problem is basically the same.

From what I guess, there must still be some issue with the networking module. In the uClinux 'make menuconfig' menu, I did not change anything in the 'Customize Kernel Settings' or 'Customize Vendor/User Settings', but left the standard values. Should I have chosen there some networking options there?
