PIC24FJ1024GB610 + FeeRTOS
Posted: 13 Aug 2018 20:51
Hi
I would like to use FreeRTOS with the PIC24FJ1024GB610. I've downloaded the examples from Libstock and created a new project using this files. The project complies Ok but when I try to debug it there is some strange behaviour. When portRESTORE_CONTEXT() is called from xPortStartScheduler() both DSWPAG and DSRPAG are set to 0 so the processor resets and starts executing from the beginning again.
In order to get the code to compile I have had to modify the portRESTORE_CONTEXT maco so that for non EADS version as shown below.
I have assumed that mikroC does not support EDS, is this correct? and is there a solution to this problem ?
Looking at the device datasheet(p75) it seem the problem is that my code is trying to set a destination address above 8000h and hence generating an address error.
Many Thanks

Code: Select all
#ifdef __HAS_EDS__
asm POP DSWPAG;
asm POP DSRPAG;
#else
//Modification as suggested in https://www.freertos.org/FreeRTOS_Support_Forum_Archive/November_2010/freertos_PSVPAG_error_PIC24FJ256DA210_3939736.html
//asm POP PSVPAG;
asm POP DSWPAG;
asm POP DSRPAG;
#endif /* __HAS_EDS__ */I have assumed that mikroC does not support EDS, is this correct? and is there a solution to this problem ?
