器件型号：TMS320F2800157
Thread 中讨论的其他器件： C2000WARE

工具与软件：

您好！

我目前正在使用 TMS320F2800157 C2000 MCU、似乎无法从闪存引导。我的开发套件和我们制造的 PCB 之间都存在这个问题。 ROM 中尚未触及引导引脚配置寄存器、因此应选择 GPIO 24和 GPIO 32作为默认引脚布线。两个引脚均通过开发套件上的开关或 PCB 上的上拉电阻器捆绑为高电平。我已经在 code composer 版本中附加了由 SYSCFG 生成的链接器文件 12.7.1.00001。我可以使用 XDS110调试器可靠地刷写和调试两个电路板上的 MCU、但在对电路板进行下电上电后、两个 MCU 都不会引导。请告诉我需要哪些其他信息才能帮助解决此问题。

谢谢、

-Alex
