nvram-faker A simple library to intercept calls to libnvram when running embedded linux applications in emulated environments.
Usually an embedded system has a certain numbers of devices interconnected via different signals. To configure these interconnections in some cases gpio are used.
>>> gpio2num = lambda a,b:(a -1)*32 + b >>> print gpio2num(7,16) 208 >>> print gpio2num(7,9) 201 num2gpio = lambda x: (x /32 + 1, x%32) >>> num2gpio(98) (4, 2)
- Mender Mender is a secure and robust software update system designed to handle large number of devices. Mender is designed according to a simple client/server architecture, allowing central management of deployments to all devices.
- RAUC is a lightweight update client that runs on your embedded device and reliably controls the procedure of updating your device with a new firmware revision
