I found integration between the freeRTOS and the nxp libraries and cmsis a confusion with the official example : [http://www.freertos.org/FreeRTOS\_Support\_Forum\_Archive/March\_2011/freertos\_FreeRTOS\_RDB1768\_examples\_with\_LPCXpresso\_4394988.html](http://www.freertos.org/FreeRTOS_Support_Forum_Archive/March_2011/freertos_FreeRTOS_RDB1768_examples_with_LPCXpresso_4394988.html) then I found the contributed source from Richard [http://www.freertos.org/Interactive\_Frames/Open\_Frames.html?http://interactive.freertos.org/forums](http://www.freertos.org/Interactive_Frames/Open_Frames.html?http://interactive.freertos.org/forums) . It seems to be the best place to start ( this port uses the CMSIS 2.0 and the peripheral library of nxp). However I wanted to start from scratch and not with full load of extra files, and I’m not sure if the project is suitable for my board, so I decided to delete off the FreeRTOS IO files, and face some mem files error (apparently it uses the heap2 configuration, I’m not familiar with this, so I copy the heap3 file from the official port). I can compile and run for now, but I really cant be sure if this is a good configuration. I will like to know: 1) Is there any particular configuration/files I should take note of? The code seems to be written for the  LPCXpresso Base Board BSP, and I am using the RDB1768v2 (same LPC1769 chip though). Also, can I actually just delete those files from the project? The files I have deleted are: FreeRTOS-Plus-CLI folder FreeRTOS-Plus-IO folder FreeRTOSIOConfig.h FreeRTOS\_IO\_BSP.h printf-stdarg.c Examples,FatFS,IwIP folder, change heap\_2.c to heap\_3.c 2) I hope it’s not too demanding, I will really appreciate if there’s a strip down version of that project. (i.e. with the freeRTOS i/o and cli removed). Any input will be much appreciated 🙂 ---
