STM32U5使用AT、netutils软件包时遇到硬中断错误

CN-Antonio commented 2 years ago

开发板为NUCLEO-U575ZI-Q，MCU型号STM32U575ZITBQU。开发环境为RT-Thread Studio 2.2.1与2.2.3，导入BSP为项目，BSP使用stm32u575-st-nucleo，pull#5802，rtt版本尝试过latest, 4.1.0, 4.0.3, 4.0.2 工具链版本需选择GNU6.3.1或10.2.1

遇到的问题为：

软件包中心添加AT-latest软件包，启用ESP8266，参数默认，编译通过，下载至开发板。运行后由uart1连接的msh反馈cpuport.c中rt_hw_hard_fault_exception函数，pc地址为0x08003268，查询为指向rt_strcmp函数。目前定位故障只能至此。

2. 软件包添加netutils，配置使能NTP客户端，其余设置默认。编译下载后，msh输入命令ntp_sync后出现类似上述硬件中断报错。定位pc为 0x0800b416，函数ntp_get_time+298

单步调试一下呢

CN-Antonio commented 2 years ago

AT-ESP8266的问题是，将断点打在main函数任何一行，开始调试，都会直接中断错误，判断最后的错误发生在rt_strcmp函数

netutils的问题是，可以进行单步调试，问题如上述所说

liukangcc commented 2 years ago

可惜，隔离在家，没有 ESP8266，没办法帮你了

mysterywolf commented 2 years ago

我用l475潘多拉帮你测了一下和这两个软件包没啥关系。应该是这个bsp本身的问题

CN-Antonio commented 2 years ago

不需要连接ESP8266，RESET后直接中断错误，启用ESP32也会报错，只需要NUCLEO的板子就可以

liukangcc commented 2 years ago

不添加软件包，bsp 运行有问题吗

CN-Antonio commented 2 years ago

直接导入BSP，编译下载没有问题，红色LED闪烁，msh不报错

CN-Antonio commented 2 years ago

这次尝试了添加AT软件包的广和通L610模组支持，同样以上问题1报错，大概是BSP存在问题。
