IQmathTablesRam: where they come from if they not in ROM Table?
In linker command file...... it LOAD the table into RAML1 but does not appear to come from ROM, why?
IQmathTablesRam : > RAML1, PAGE = 1
Can it be placed in FLASH instead (FLASHA)?

IQmathTablesRam are built into the ".lib" file - its used by IQasin, IQacos, and IQexp
The tables in ROM are for division, IQsin, IQcos, IQatan, IQatan2

yes you can, but for speed its better to copy over to RAM as follows:
1. in the linker command file, declare the section as
IQmathTablesRam: LOAD = FLASHA, RUN = RAML0, LOAD_START(_IQmathTablesRamLoad), RUN_START(_IQmathTablesRamRun), LOAD_SIZE(_IQmathTablesRamSize), PAGE = 0
2. in main.c, declare
#include <string.h> extern uint16_t IQmathTablesRamLoad, IQmathTablesRamRun, IQmathTablesRamSize ; memcpy((uint16_t *)&IQmathTablesRamRun, (uint16_t *)&IQmathTablesRamLoad, (uint16_t)&IQmathTablesRamSize);
