make

My part of the project has been to make it possible to run the Ethernut software on a custom developed hardware.

Ethernut is an open source project.

Embedded Linux Development (2005)

Techniques:

Embedded
Linux
SNMP
bash
make

My part of the project has been to develop and maintain software for an embedded Motorola PowerPC based environment. I have basically worked with the SNMP client and the startup scripts.

Development Environment Administrator (2005)

Techniques:

Linux
Cross-compiler
make
bash
Perl

I worked with maintainens of an AMD64 cross-compiler development environment for an embedded Motorola PowerPC based target. Both the host and the target were running Linux.

Alarm Monitor Software (2005)

Techniques:
