连接 gdb 时出现 ocd 断言错误

Question

我正在使用 openocd 和 arm-none-eabi-none 在 Ubuntu 20.04 上调试板 STM32f4 Discovery。直到昨天一切都很好。今天，当我将 gdb 连接到 localhost:4444 时，发生了以下断言并且 ocd 退出：

我看到它正在使用 stm32f2x.c，芯片是 stm32f407vgt，是否正确？

Answer 1

我发现了问题：我在没有切换到适当的闪存延迟的情况下提高了时钟速度，因此调试器将丢失程序地址的轨道，如此处提到的，在时钟和初始设置部分： https://vjordan.info/log/fpga/first-steps-with-the-stm32f4.html
