3. 提供解决RISC-V Load Access Fault的一些建议方法 检查内存权限:确保当前处理器模式具有访问目标内存区域的足够权限。 审查PMP配置:如果使用了PMP,检查PMP配置以确保没有错误地阻止了对合法内存区域的访问。 验证内存映射:确认目标内存地址已被正确映射到物理内存,并且映射是有效的。 调试和日志记录:在异常处理程序...
Description I'm purposely trying to access unmapped memory to trigger load fault. Since the memory starts at 0x80000000 I'm accessing address below it, like 0x80000000 - 2 = 0x7ffffffe. When accessing this address via lh instruction, the...
存在的问题:(1)在芯片上电启动后,会开始进入“Load access fault”异常,然后线程会正常调度;(2)线程能正常运行几分钟左右后,便会卡死。请问进入“Load access fault”异常的原因是什么啊?以及线程卡死,是否与其有关系呢?另外,上述的移植过程还有哪里需要完善和改进吗?请大佬指点。 离线 #1...
RISC-V的StoreAMO access fault调试实例 本文以一个实例分享RISC-V的StoreAMO access fault异常的调试过程。StoreAMO access fault主要发生在非法地址访问时(栈溢出,指针异常等)。 2023-06-08 11:10:12 解析汽车抛负载LoadDump:loaddump产生原因与TVS并联保护方案 ...
I will cite arch/riscv code here but I see the same pattern in other arches. arch_new_thread() does not entirely initialize its exception stack frame, rather it only initializes the subset of esf data necessary to get to z_thread_entry() on return from the exception handler. Not ...
