[参考译文] MSPM0G3107：从引导加载程序跳转到应用程序后、计时器不工作

您好、Sara：

您可以尝试使用以下代码从引导加载程序跳转到 APP：

__STATIC_INLINE void invokeBSLAsm(void)
{
    /* Erase SRAM completely before jumping to BSL */
    __asm(
#if defined(__GNUC__)
        ".syntax unified\n" /* Load SRAMFLASH register*/
#endif
        "ldr     r4, = 0x41C40018\n" /* Load SRAMFLASH register*/
        "ldr     r4, [r4]\n"
        "ldr     r1, = 0x03FF0000\n" /* SRAMFLASH.SRAM_SZ mask */
        "ands    r4, r1\n"           /* Get SRAMFLASH.SRAM_SZ */
        "lsrs    r4, r4, #6\n"       /* SRAMFLASH.SRAM_SZ to kB */
        "ldr     r1, = 0x20300000\n" /* Start of ECC-code */
        "adds    r2, r4, r1\n"       /* End of ECC-code */
        "movs    r3, #0\n"
        "init_ecc_loop: \n" /* Loop to clear ECC-code */
        "str     r3, [r1]\n"
        "adds    r1, r1, #4\n"
        "cmp     r1, r2\n"
        "blo     init_ecc_loop\n"
        "ldr     r1, = 0x20200000\n" /* Start of NON-ECC-data */
        "adds    r2, r4, r1\n"       /* End of NON-ECC-data */
        "movs    r3, #0\n"
        "init_data_loop:\n" /* Loop to clear ECC-data */
        "str     r3, [r1]\n"
        "adds    r1, r1, #4\n"
        "cmp     r1, r2\n"
        "blo     init_data_loop\n"
        /* Force a reset calling BSL after clearing SRAM */
        "str     %[resetLvlVal], [%[resetLvlAddr], #0x00]\n"
        "str     %[resetCmdVal], [%[resetCmdAddr], #0x00]"
        : /* No outputs */
        : [ resetLvlAddr ] "r"(&SYSCTL->SOCLOCK.RESETLEVEL),
        [ resetLvlVal ] "r"(DL_SYSCTL_RESET_BOOTLOADER_ENTRY),
        [ resetCmdAddr ] "r"(&SYSCTL->SOCLOCK.RESETCMD),
        [ resetCmdVal ] "r"(
            SYSCTL_RESETCMD_KEY_VALUE | SYSCTL_RESETCMD_GO_TRUE)
        : "r1", "r2", "r3", "r4");
}

谢谢！

此问题已解决、我无法正确擦除闪存。
