Hi, while investigating the max. FIQ latency on a LPC2294 (other LPC should be similar), I wrote following code which fits completly into the vector table and allows a total of 7 (or 5 with synchronisation with an RTOS or higher layer) instructions to be executed without a branch. It uses vectaddr14 and vectaddr15 of the VIC to store the Abort and

Hello All, I am searching from a suitable open source OS for ARM7 controllers. I looked into a number of them; contiki, pico OS and FreeRTOS. I think FreeRTOS is the best among all these. One important reason for me to choose FreeRTOS is that it has an active forum which I did not find for pico OS otherwise that too could have been a good choice. Contiki on the other hand, ...

Can I have some recommendations on tooling up to use the 2129? We use ARMs, but under Linux, and almost never at the kernel debug, or JTAG level. Now I'm looking at working with the L2129. I guess I'll be working on bare metal, or possibly a simple RTOS. So I need to get to grips with IPS/JTAG programming and some editor-compiler-linker-debugger chain. What sort of tools would I want to...

Ok, just as an idle thought what sort of mechanisms do people use when trying to determine how much of the processing usage is actually being used? This stems from doing some experiments with an FreeRTOS based device . I tried counting tick events in an idle handler and then deriving load from that but I don't think this takes into account the fact that tasks may be suspended partway thr...
