Aug.22 eCos Configuration

Open eCos LMS topics:

• Optimize eCos
• Can / how or how much can thumb instructions be used instead of ARM cmds?
• http://ecos.sourceware.org/docs-1.3.1/tutorials/arm/ecos-tutorial.11.html
• eCos may require all Thumb or all ARM - comments in code around use of Thumb flag indicate  problems when using Thumb for interrupts
• http://nxtgcc.sourceforge.net/EMSOFT-2009-Mindstorms-Tutorial.pdf  p.64
• Lego FW uses thumb except for interrupts
• Sensor/Motor related
• Change system clock from TC0 to PIT (since 3 TCxs allow edge counting)
