hi @Hermann

Could you provide the Software version (uname -a) of your module? Which carrier board are you using?

To install gdb please do the following:

opkg update list
opkg install gdb

Best regards, Jaski

Thank you for yor answer.

But

opkg install gdb

causes

Unkown package ‘gdb’.
Collected errors:

opkg_solver_install: Cannot install package gdb.

???

Could you provide your software version?

Hi Jaski,

here is the answer to your question:

root@colibri-imx6:~# uname -a

Linux colibri-imx6 4.1.39-2.7.2+gba2f75f #3 SMP Mon Apr 10 03:01:06 CEST 2017 armv7l GNU/Linux

Thanks for this Information. Bsp 2.7.2 is not supported anymore. Could you update to at least Stable 2.7 release or even better to 2.8b5? Thanks.

Hermann · January 11, 2019, 11:24am

Hi Jaski,

yesterday I started

opkg upgdate
opkg upgrade

and that caused my problem with gdb.

How can I upgrade to 2.8 ?

jaski.tx · January 11, 2019, 11:53am

As written here the command opkg upgrade will lead to a unusable system. For updating the module, you should use the Toradex Easy Installer.

Hermann · January 14, 2019, 6:32am

Hallo Jaski,

you are right.
I tried a second upgrade an now the iMX6 doesn’t boot.

Thank you for your answers.

Best regards

jaski.tx · January 14, 2019, 7:07am

Thanks for you input. Were you able to reinstall a booting version of Linux with GDB?

Hermann · January 14, 2019, 7:47am

What bust be done to make the iMX6 able to start the app shown on the attached jpg ?
Is there a description, please ?

jaski.tx · January 14, 2019, 10:26am

As explained under the following link, you should put the module to the recovery mode and then load the Toradex Easy Installer to the module using USB OTG Connection.

Hermann · January 14, 2019, 5:06pm

Hallo Jaski,

the iMX6 works again, I installed Bsp 2.7.2.
Now two questions are left:

setxkbmap de

changes y and z and the some other keys but the keys ÄÖÜ don’t work.

and

opkg install gdb

causes

Cannot install package gdb

Best regards

jaski.tx · January 14, 2019, 11:18pm

Perfect that it works again. Could you install the Bsp 2.8b5 instead of 2.7.2?

Hermann · January 15, 2019, 5:48am

Hallo Jaski,

Bsp 2.8b5 is installed.
GDB can be startet.

But now I 'm missing gcc ?

opkg install gcc

causes

No packages installed or removed

Best regards

jaski.tx · January 15, 2019, 10:05am

I think gcc is already installed. Did you try to run gcc? Try the command arm-angstrom-linux-gnueabi-gcc, please.

Hermann · January 15, 2019, 1:52pm

Hallo Jaski,

“arm-angstrom-linux-gnueabi-gcc” works.

How can I achieve, that “arm-angstrom-linux-gnueabi-gcc” can be called with a simple “gcc” ?
My cross-platform expects “gcc” and I have no idea how to change it.

Best regards

jaski.tx · January 15, 2019, 5:18pm

you can do a symbolic link or change the configuration of your cross-platform Toolschain. Further it is not recommended to do the compilation on the module but use a cross compiler platform on the host.

Hermann · January 15, 2019, 8:08pm

Hallo Jaski,

thank you very much for your reply.

Every coin has two sides.

There are advantages and disadvantages to use a cross-compiler or compiling on the target.

One advantage of compiling on the target is: it only needs gcc, gdb and gdb-server on the target and I can do my job on several hardware-platforms and BSPs.

And why is at toradex
gdb == gdb,
gdb-server == gdb-server
and gcc == arm-angstrom-linux-gnueabi-gcc ?
What is it good for ?

Now I have to care how to get a symbolic link.

Best regards
