I tried to have a union in the EEPROM memory but Ride7 keeps crashing (during build)
any ideas?

the union was declared as follows:

in data.h file -

union active_chair_data
{
u8 chair_data[40];
struct
{
u16 cycle_on_time;
u16 cycle_off_time;
u16 continuous_time;
u16 reset_position_time;
u16 pause_time;
u16 restart_after_pause_time;
u16 start_after_sitting_time;
u16 pwm_cycle_time;
u16 pwm_on_time;
u16 get_up_time;
u16 spare2;
u16 spare3;
u16 spare4;
u16 spare5;
u16 spare6;
u16 spare7;
u16 spare8;
u16 spare9;
u16 spare10;
u16 spare11;
}par;
};

extern union active_chair_data eeprom chair_eeprom;

and in data.c file-

union active_chair_data eeprom chair_eeprom;

I have another variable declared as this union but it is located in RAM, I believe it should not present a problem.
extern union active_chair_data chair_value; (in h file)
union active_chair_data chair_value; (in c file)

I tried different locations for the eeprom directive (once before and once right after the union (union eeprom active_chair_data chair_eeprom; and eeprom union active_chair_data chair_eeprom;) the compiler crashed.

I need the variables to be in the EEPROM in successive addresses so I can write them using a flash programming at the same time without calling the function many times (40 byte write to flash at one go)

thanks
