尊敬的专家：
您能否提供几行将内核寄存器读取到变量的示例？ 例如 SP 寄存器。
谢谢、
挂起。
您好 Hang、
请参阅以下示例。 SP 加载 R0指向的地址处的内容。 R0稍后会加载地址 APP_START_ADDRESS + 4处的值。
;; ;; Load the stack pointer from the application's vector table. ;;movw r0, #(APP_START_ADDRESS & 0xffff)movt r0, #(APP_START_ADDRESS >> 16) ldr sp, [r0]
;;
;; Load the stack pointer from the application's vector table.
movw r0, #(APP_START_ADDRESS & 0xffff)
movt r0, #(APP_START_ADDRESS >> 16)
ldr sp, [r0]
;; ;; Load the initial PC from the application's vector table and branch to ;; the application's entry point. ;; ldr r0, [r0, #4] bx r0
;; Load the initial PC from the application's vector table and branch to
;; the application's entry point.
ldr r0, [r0, #4]
bx r0
尊敬的 Charles：
感谢您的示例。 如何将它们置于 C 环境中？
您可以在 C 代码中嵌入汇编代码、如下例所示。
asm (" LDR sp、[r0])；
