TI中文支持网Part Number:TMS570LS3137
型号：TMS570LS3137
使用HAL CODE生成的驱动代码以及F021库F021_API_CortexR4_BE_L2FMC_V3D16.lib 擦除和烧写FLASH BANK0 BANK1 BANK7不成功。
但是根据官方文档编写的例程，程序显示擦除和烧写成功，不知道为什么？
备注：芯片OSC:16M，HCLK:180M
代码如下：

* return：

enum e_flash_status Flash_EraseBanks(Fapi_FlashBankType oNewFlashBank)
{
int num = 0;

num = find_sector(oNewFlashBank, 0);
oReturnCheck = Fapi_initializeFlashBanks(180); //初始化Flash Bank以进行API操作
if((oReturnCheck == Fapi_Status_Success) && (FLASH_CONTROL_REGISTER->FmStat.FMSTAT_BITS.BUSY != Fapi_Status_FsmBusy))
{
oReturnCheck = Fapi_setActiveFlashBank(oNewFlashBank); //设置活动的Flash Bank
if( (oNewFlashBank == Fapi_FlashBank0) || (oNewFlashBank == Fapi_FlashBank1) )
oReturnCheck = Fapi_enableMainBankSectors( 0xffffffff ); //设置EEPROM存储区中可用的扇区以进行擦除和编程

您好我们已收到您的问题并升级到英文论坛，温馨提示您由于圣诞节及新年假期，英文论坛的回复将稍晚。敬请谅解！

Cherry Zhou：
您好，F021_API_CortexR4_BE_L2FMC_V3D16.lib 适用于 TMS570LC43x 和 RM57x。 F021_API_CortexR4_BE_V3D16.lib 或 F021_API_CortexR4_BE.lib 应用于 TMS570LS3137 器件。

换了F021_API_CortexR4_BE.lib 可以擦除和烧写BANK1了，但是无法擦除和烧写BANK0。
备注：启动程序在BANK0中执行，sys_link.cmd如下：

还是BANK7是不是不能使用F021_API_CortexR4_BE.lib来擦除和烧写？
,
shen zhi：
擦除BANK1最后一块0x2E0000时，显示一直处于while(FAPI_GET_FSM_STATUS != Fapi_Status_Success);循环挂起中。
for (i=ucStartSector; i<(ucEndSector+1); i++){ Fapi_issueAsyncCommandWithAddress(Fapi_EraseSector, flash_sector[i].start); while( FAPI_CHECK_FSM_READY_BUSY == Fapi_Status_FsmBusy ); while(FAPI_GET_FSM_STATUS != Fapi_Status_Success); }

Cherry Zhou：
抱歉回复晚了。
1. 要擦除bank0部分，必须将flash API 相关代码复制到 SRAM ，并且从 SRAM 执行。
2. 如果您要把 Bank 7用作 FEE，请使用FEE drivers来写入/读取数据， 并使用FEE driver擦除flash.
shen zhi 说：擦除BANK1最后一块0x2E0000时，显示一直处于while(FAPI_GET_FSM_STATUS != Fapi_Status_Success);循环挂起中。
您看下最后一个sector (sector 11)有没有启用擦除。
Fapi_enableMainBankSectors(0xFFFF); –> to enable sector 0 to sector 15
