TMS320F28388D: 28388D 双核程序升级的思路

另外请教一个问题，在cup1使用中FlashApi可以对flash进行擦写操作，但是cpu2使用该方式就没法擦写flash，同样的代码，内部函数中有关CPU1和CPU2选择的部分已经处理了，请问这CUP1和CPU2在擦写FLASH有什么不同吗？

这是CPU1的代码，可以执行擦写操作

SeizeFlashPump();
EALLOW;
oReturnCheck = Fapi_initializeAPI(F021_CPU0_BASE_ADDRESS, 200);

if(oReturnCheck != Fapi_Status_Success)
{
//Example_Error(oReturnCheck);
return false;
}
oReturnCheck = Fapi_setActiveFlashBank(Fapi_FlashBank0);
if(oReturnCheck != Fapi_Status_Success)
{
return false;
}
oReturnCheck = Fapi_issueAsyncCommandWithAddress(Fapi_EraseSector,
(uint32 *)Bzero_SectorD_start);

while(Fapi_checkFsmForReady() != Fapi_Status_FsmReady){}


oReturnCheck = Fapi_doBlankCheck((uint32 *)Bzero_SectorD_start,
Bzero_16KSector_u32length,
&oFlashStatusWord);

if(oReturnCheck != Fapi_Status_Success)
{

// Example_Error(oReturnCheck);
return false;
}

for(i=0;i<4;i++)
{
Buffer[i*2] = mflagWord;
Buffer[i*2 + 1] = cpu_selected;
}



for(i=0, u32Index = Bzero_SectorD_start;
(u32Index < (Bzero_SectorD_start + 8)) &&
(oReturnCheck == Fapi_Status_Success); i+= 8, u32Index+= 8)
{
oReturnCheck = Fapi_issueProgrammingCommand((uint32 *)u32Index,Buffer,
8,
0,
0,
Fapi_AutoEccGeneration);

while(Fapi_checkFsmForReady() == Fapi_Status_FsmBusy);

if(oReturnCheck != Fapi_Status_Success)
{
// Example_Error(oReturnCheck);
return false;
}

oFlashStatus = Fapi_getFsmStatus();
// oReturnCheck = Fapi_doMarginRead((uint32 *)u32Index,debug32buf+(i/2),4, Fapi_NormalRead);

if(oReturnCheck != Fapi_Status_Success)
{
// Example_Error(oReturnCheck);
return false;
}

}
EDIS;
ReleaseFlashPump();
return true;

这是CPU2的代码 无法进行擦写FLASH

CPU2SeizeFlashPump();
EALLOW;
oReturnCheck = Fapi_initializeAPI(F021_CPU0_BASE_ADDRESS, 200);

if(oReturnCheck != Fapi_Status_Success)
{
//Example_Error(oReturnCheck);
return false;
}
oReturnCheck = Fapi_setActiveFlashBank(Fapi_FlashBank0);
if(oReturnCheck != Fapi_Status_Success)
{
return false;
}
oReturnCheck = Fapi_issueAsyncCommandWithAddress(Fapi_EraseSector,
(uint32 *)Bzero_SectorD_start);

while(Fapi_checkFsmForReady() != Fapi_Status_FsmReady){}


oReturnCheck = Fapi_doBlankCheck((uint32 *)Bzero_SectorD_start,
Bzero_16KSector_u32length,
&oFlashStatusWord);

if(oReturnCheck != Fapi_Status_Success)
{

// Example_Error(oReturnCheck);
return false;
}

for(i=0;i<4;i++)
{
Buffer[i*2] = mflagWord;
Buffer[i*2 + 1] = cpu_selected;
}



for(i=0, u32Index = Bzero_SectorD_start;
(u32Index < (Bzero_SectorD_start + 8)) &&
(oReturnCheck == Fapi_Status_Success); i+= 8, u32Index+= 8)
{
oReturnCheck = Fapi_issueProgrammingCommand((uint32 *)u32Index,Buffer,
8,
0,
0,
Fapi_AutoEccGeneration);

while(Fapi_checkFsmForReady() == Fapi_Status_FsmBusy);

if(oReturnCheck != Fapi_Status_Success)
{
// Example_Error(oReturnCheck);
return false;
}

oFlashStatus = Fapi_getFsmStatus();
// oReturnCheck = Fapi_doMarginRead((uint32 *)u32Index,debug32buf+(i/2),4, Fapi_NormalRead);

if(oReturnCheck != Fapi_Status_Success)
{
// Example_Error(oReturnCheck);
return false;
}

}
EDIS;
CPU2ReleaseFlashPump();
return true;

你好，还有个问题，28388D的FLASH_API只提供了Verify的函数，没有读取FLASH的函数，28377D的库函数有这个读取的功能，在388D读取FLASH需要什么样的操作呢？

377D的库函数，这里面有Fapi_doMarginRead 这个读取FLASH的函数

/* Read commands */
extern Fapi_StatusType Fapi_doBlankCheck(
uint32 *pu32StartAddress,
uint32 u32Length,
Fapi_FlashStatusWordType *poFlashStatusWord
);

extern Fapi_StatusType Fapi_doMarginRead(
uint32 *pu32StartAddress,
uint32 *pu32ReadBuffer,
uint32 u32Length,
Fapi_FlashReadMarginModeType oReadMode
);

extern Fapi_StatusType Fapi_doVerify(
uint32 *pu32StartAddress,
uint32 u32Length,
uint32 *pu32CheckValueBuffer,
Fapi_FlashStatusWordType *poFlashStatusWord
);

388D的库函数 ，正好缺少了这个读取的函数

/* Read commands */
extern Fapi_StatusType Fapi_doBlankCheck(
uint32 *pu32StartAddress,
uint32 u32Length,
Fapi_FlashStatusWordType *poFlashStatusWord
);

extern Fapi_StatusType Fapi_doVerify(
uint32 *pu32StartAddress,
uint32 u32Length,
uint32 *pu32CheckValueBuffer,
Fapi_FlashStatusWordType *poFlashStatusWord
);

extern Fapi_StatusType Fapi_doVerifyBy16bits(
uint16 *pu16StartAddress,
uint32 u16Length,
uint16 *pu16CheckValueBuffer,
Fapi_FlashStatusWordType *poFlashStatusWord
);

对于F28388，所有提供的FLASH API函数都在该doc中给出了

你好，在应用过程中出现了一个问题，CPU1调用IpcInit()功能后再调用Fapi_issueAsyncCommandWithAddress(Fapi_EraseSector,
(uint32 *)Bzero_SectorD_start)这个函数擦除SECTOR，擦除地址是0X86000,则会将0x86000以后的FLASH全部擦除，如果不调用IPC_Init ，该函数运行正常，只擦除0x86000~0x88000 这一个SECTOR，这是什么原因导致的呢
