I am interested in how other small electronics companies handle their End-of-Line testing and programming.

I am working for a small company (2.5 firmware devs, 2.5 software devs and 1 hardware guy)

We design and sell small electronic devices (RFID Reader), let them produce by a partner company but provides them with custom hardware and software to perform End-of-Line testing and programming.

I have inherited this EOL testing software and now need to maintain and implement new features, but it is a huge mess. So we are looking into replacing everything.

Currently everything is written in Python (the main language for software in the whole company) We flash a custom test firmware the DUT and perform different tests LED flashing Buzzer working RFID range Various Interfaces (USB, Erhernet/PoE, Rs485, Rs232, Bluetooth …) At the end we program the final firmware and configuration into the device and print labels.

Currently everything is homebrewed (software and hardware) and I am interested in more off the shelf solutions which can be customized.

How are you tackling this in your company?
