magicse7en b9748e50ea Xtensa: fix stack overlap coproc_area issue (#118) ... In function pxPortInitialiseStack of port.c: sp = ( StackType_t * ) ( ( ( UBaseType_t ) ( pxTopOfStack + 1 ) - XT_CP_SIZE - XT_STK_FRMSZ ) & ~0xf ); We assume XT_CP_SIZE is 0xE4, XT_STK_FRMSZ is 0xA0, pxTopOfStack is 0xA0000000, sp is 0x9FFFFE80. From port.c, we know the frame->a1 as below: frame->a1 = ( UBaseType_t ) sp + XT_STK_FRMSZ; /* physical top of stack frame */ So frame->a1 is 0x9FFFFF20. Therefore the interrupt stack frame range is 0x9FFFFE80 ~ 0x9FFFFF20. The coproc_area is: p = ( uint32_t * ) ( ( ( uint32_t ) pxTopOfStack - XT_CP_SIZE ) & ~0xf ); So its value is 0x9FFFFF10. Obviously, the interrupt stack frame overlaps the coproc_area. Co-authored-by: Carl Lundin <53273776+lundinc2@users.noreply.github.com>		2020-10-26 11:07:32 -07:00
