RTOS¶

page to save some thoughts on firmware directions

current situation for released firmware:

• build online on mbed.org
• using closed mbed libs for e.g. ethernet

next step

• do offline compiling using gcc4mbed ->works now!
• still using mbed libs

When making a step away from the mbed libs, we probably also need to look for an alternative of the MBED e.g. LPC1768. -> not required due to open sourcing mbed libs

feature list for new firmware environment

• open source
• ethernet support
• build environment in linux
• support for cortex-m3
• board support for LPC1768 / LCP1769
• RTOS
• easy to implement in the current code
• ethernet based on lwip (same as current code...)

some alternatives (based on being open source and cortex-m3 support)

for now, this is a start of getting to know the firmware structure:
