Before getting started with the Timesys Factory, make sure the host
system has all of the required software packages. Run the
checksystem make target from within the factory directory to scan
your host system for required software. This utility will inform you of
any missing host requirements and how to resolve them.
$ make checksystem
•
Running the build environment as the root user is discouraged in
order to ensure the safety of the host work station.

•
toolchain -- build and package the cross toolchain
•
host-utilities -- build the host utilities
•
rfs -- compile all the selections and kernel and create the RFS output
•
rfs-images -- generate the RFS images (called by RFS)
•
packages -- generates packages for all selections
•
installer -- generates the installer for the factory distribution
•
distclean -- purges build directories and files
•
rfs-distclean -- reset RFS working directory

MQX 4.0.1 Beta 2 - updated from Beta 1
•
mcc-accelerometer-demo
−
•
This is an MCC application that will output accelerometer data to the MQX terminal.
mcc-webgl-accelerometer-demo
−
This is an MCC application that serves WebGL 3D pages to render Vybrid tower tilting in real time.
•
Bug fixes
•
For Vybrid Tower board kernel:
−
Serial driver fix in Linux kernel for binary transfer of files from host to target via serial.
−
While(1) fix in Vybrid Linux kernel.

A program that consumed 100% CPU cycles starved any other running processes of CPU
bandwidth. A kernel patch related to the scheduler for Vybrid has fixed this issue.
•
Known Issues
•
A race condition in MCC can cause one side to send a buffer while the other side is deleting the
endpoint
