我尝试在 uVision（设备：Arm7）中翻译此代码，但我得到 9 个错误，这是怎么回事？我觉得我的配置是错误的。谢谢

/* Daten-Bereich */
AREA   Daten, DATA, READWRITE
Wert: DW  10
 Quadrat:DS 4

 /********************************************************************/
    /* Programm-Bereich */
  AREA   Programm, CODE, READONLY, AT 0x00000000
  Reset_Handler:  MSR     CPSR_c, #0x10 ; User Mode aktivieren
  /********************************************************************/

            LDRH    R1,[R3]         ; Wert laden
            MUL     R2,R1,R1        ; Quadrat bilden
            LDR     R3,=Quadrat     ; Adresse des Quadrats 
            STR     R2,[R3]         ; Quadrat ablegen

            END

您是否尝试在启动文件中进行更改？使用嵌入式 C 语言编写此代码会容易得多...

考虑一下！！
