Posted on May 17, 2011 at 09:54 I've a problem with bank switch in STR912W42X6
I would use bank0 to restore data ,when i write data in FMI_B0S2 ,why FMI_B0S3 have same data with FMI_B0S2.
__ramfunc u8 EepromFormat(){
u16 gg1,gg2
SCU_AHBPeriphClockConfig(__FMI, ENABLE);
SCU_AHBPeriphReset(__FMI, DISABLE);
SCU_PFQBCCmd(DISABLE);
SCU_AHBPeriphReset(__VIC, ENABLE);
FMI_BankRemapConfig(0x0, 0x6,0x80000, 0x0);
FMI_WriteProtectionCmd(FMI_B0S2, DISABLE);
FMI_WriteProtectionCmd(FMI_B0S3, ENABLE);
FMI_EraseSector(FMI_B0S2);
FMI_Timeout_Status1 = FMI_WaitForLastOperation(FMI_BANK_0);
gg1=FMI_ReadWord(FMI_B0S2);
if(gg1==0xffff)
{
FMI_WriteHalfWord( FMI_B0S2,0xAAAA );// write data to FMI_B0S2
FMI_WaitForLastOperation(FMI_BANK_0);
}
gg2= FMI_ReadWord(FMI_B0S3);//gg2 is the same whith FMI_B0S2
}
