大家好、
我正在使用 TM4C1294 EVK ,这里我正在 尝试通过以太网固件升级来刷写.hex 文件,我可以通过以太网将 hex 文件写入闪存,使用 TCP IP 与外部应用程序从笔记本电脑加载二进制文件
但以太网在打开时也会写入其他应用程序(铬)中的垃圾值,以及 hex 文件
您能建议如何解决此问题吗？
您是否还能帮助我们 使用 TM4C1294 EVK 的 TCP IP 数据包、与引导加载程序一起或不一起共享用于以太网固件升级的任何工作示例代码
请帮助我们完成以太网固件升级的示例项目和文档
请 尽快响应
您好！
假设您使用 LM 闪存编程器来更新您的固件。 但思路与要使用的其他工具相同、例如 eflash.exe。 在 LM 闪存编程器中、您需要指定客户端 IP 地址和 MAC 地址。 您是这么做的吗？ 常见的 TivaWare 引导加载程序是一款重量非常轻的堆栈、不包含 DHCP 应用层(OSI 层7)代码。 boot_demo_EMAC_flash 也是如此。 要将 IP 地址输入到 LM 闪存编程器中、您需要运行另一个示例、例如 enet_lwip 或 enet_io 或任何获取 IP 地址的示例。 获取 IP 地址后、您将在引导加载程序示例的 LM 闪存编程器中输入该地址。 原因是 DHCP IP 地址通常由网络上的 DHCP 服务器租用给您。 IP 地址将保留一段时间。 必须将该 IP 地址和 MAC 地址对输入充当 BootP/TFTP 服务器的 LM 闪存编程器。
我强烈建议您首先运行常用示例； boot_emac_flash 作为引导加载程序、boot_demo_emac_flash 作为 LaunchPad 上的应用固件。 在继续进行自定义引导加载程序之前、请确保它能够正常工作。
当我尝试将固件地址 chage 到 0x40000000
IAM 出现以下错误
您好、这是我的.cmd 文件您可以更改 地址值并请恢复
