9S08MP16 Flash (reserve a partition for system fault)

kazbi — Thu, 05 May 2011 16:35:50 GMT

Hello,

I´m using the DEMO9S08MP16 (16KB Flash) on my prototype with Code Warior Processor Expert and I would like to use some adresses for my fault handling.

So as following, I choose the adresses( 0xFA00, 0xFA01...).

#define DLK_V_Warning() IFsh1_SetByteFlash(0xFA00,10)
#define DLK_V_Fault() IFsh1_SetByteFlash(0xFA00,11)

#define DLK_T_Fault() IFsh1_SetByteFlash(0xFA01,11)
#define DLK_T_Warning() IFsh1_SetByteFlash(0xFA01,10)

When a fault (B) or warning(A) occurs it schould be saved wtih the defined function.

My Problem:

I don´t know how I can reserve some adresses for my fault and warning handling witout perturbing my realtime program in the flash.

Best regards

Hello,

I think that better way will be to set your flags to end of non-volatile memory, that means exactly to 0xFFAC and 0xFFAD and after that exclude this area from linking process of your regular code using the following steps:

- go to the build options tab in CPU component
- Set Size of the Memory Area0 (Name: ROM) to 3FAC

Thank you Filip,

I try your konfiguration, but I in the non-volatile memory is only 00 in all reserved adresses.

I don´t see the fault or Warning??

I have 10 Fault and I set the memory area0 size to 3FA4.

so it beginn from 0xFFA4 to 0xFFAD.

#define D_V_Warning() IFsh1_SetByteFlash(0xFFA4,10)
#define D_V_Fault() IFsh1_SetByteFlash(0xFFA4,11)

#define D_T_Fault() IFsh1_SetByteFlash(0xFFA5,11)
#define D_T_Warning() IFsh1_SetByteFlash(0xFFA5,10)

#define D_L_Fault() IFsh1_SetByteFlash(0xFFA6,11)

#define D_C_Fault() IFsh1_SetByteFlash(0xFFA7,11)
#define D_C_Warning() IFsh1_SetByteFlash(0xFFA7,10)

#define B_V_Fault() IFsh1_SetByteFlash(0xFFA8,11)
#define B_V_Warning() IFsh1_SetByteFlash(0xFFA8,10)

#define B_T_Fault() IFsh1_SetByteFlash(0xFFA9,11)
#define BORD_T_Warning() IFsh1_SetByteFlash(0xFFA9,10)

#define B_Ion_Fault() IFsh1_SetByteFlash(0xFFAA,11)

#define B_Ioff_Fault() IFsh1_SetByteFlash(0xFFAB,11)

#define INF_Fault() IFsh1_SetByteFlash(0xFFAC,11)

#define PYRO_Fault() IFsh1_SetByteFlash(0xFFAD,11)

Best Regards
