TMS320F28377S: 我用tms320f28377s做flash固件升级相关问题

否，擦除FLASHA时必须保留bank选择逻辑。
对于固件更新，F2837xD没有示例实现。一个很好的起点是F2837xD的SCI闪存内核示例，并使用F28004x等其他设备的固件更新实现。

 Serial Flash Programming of C2000 Microcontrollers, Live Firmware Update with Device Reset on C2000 MCUs (Rev. A), and Live Firmware Update Without Device Reset on C2000 MCUs (Rev. B) 都是有用的应用程序说明。

如果FLASHA无法完全擦除的话，我的代码只能从FLASHB开始？还有其他的方案吗？

   #define Bzero_SectorA_start	       0x80000
  Uint16 backupBeginData; // 用于在RAM中备份BEGIN数据


    Uint16 *beginAddress = (Uint16 *)0x080000; // BEGIN区域的起始地址

    
   // 1. 备份BEGIN区域的数据
    backupBeginData = *beginAddress; // 读取2字节数据
