Systém pro programování a testování zařízení s procesory ARM

Presented system aims to mass production where it is used to program devices with ARM Cortex M CPU by IAP protocol and to test the produced devices with Ethernet interface. For interaction with user, the programmer contains LCD display and group of buttons. Thanks to this solution, it is possible to program device with one of the firmware images stored in the internal memory of programmer and it is also possible to change some constants such as MAC address. Other part of this thesis describes a system for testing devices with RJ-45 connectors in temperature test chamber. The device is exposed to fast temperature changes to discover hardware errors. Testing is realized by sending packets through the tested device and measuring packets loss during different temperatures in chamber. System displays results of testing as graphs of packets loss over time.
