Harmony V1.06 Bootloader基本应用无法启用u***总线

大家好，我试图在“u***host_pic32mz_ec_sk”配置中使用引导加载程序basic的示例应用程序。设备被更改为PIC32 MZ1024EC144.2。配置位a.#pragma config ICESEL=ICS_PGx2 to ICS_PGx1 b.#pragma config FCKSM=CSDCMD to CSECME c.#pragma config FPLLMULT=MUL_50 to MUL_100 d.#pragma config UPLLFSEL=FREQ_24MHZ to FREQ_12MHZ//使用12Mhz晶体而不是24MHz3。为了避免在Bootloader_Tasks()中按BTL开关启用引导，一些行被注释，如图所示；情况BOOTLOADER_CHECK_._PROGRAM: {/*检查用户重置地址是否被擦除。*//if(0xFFFFFFFFFF===*(无符号int*)BOOTLOADER_RESET_ADDRESS) {bootloaderData.currentState=BOOTLOADER_OPEN_DATASTREAM; }//否则{/*用户重置地址不被擦除。启动程序。*//bootloaderData.currentState=BOOTLOADER_ENTER_.;}break;}在进行这些更改之后，我的引导加载程序应用程序状态没有超过BOOTLOADER_WAIT_._HOST_ENABLE。任何建议都是非常欢迎和感谢的。请注意：硬件与SD卡的MSDFATFAX多磁盘应用程序运行良好。所以我不认为有任何硬件配置问题。谢谢，SunilP。

    Hello guys,
i am trying to using demo application of boot loader basic in "u***host_pic32mz_ec_sk" configuration.
What changes i have done are:
1. Device is changed to PIC32MZ1024ECH144.
2. Configuration Bits
    a. #pragma config ICESEL =     ICS_PGx2  to ICS_PGx1
    b. #pragma config FCKSM =      CSDCMD to CSECME
    c. #pragma config FPLLMULT =   MUL_50   to MUL_100  
    d. #pragma config UPLLFSEL =   FREQ_24MHZ  to FREQ_12MHZ     // to use 12 Mhz Crystal instead of 24 MHz
3. to avoid BTL switch press to enable bootlaoding in Bootloader_Tasks()  some lines are commented as shown;

           case BOOTLOADER_CHECK_FOR_PROGRAM:
          {
               /* Check if the User reset address is erased. */
                 //if (0xFFFFFFFF == *(unsigned int *)BOOTLOADER_RESET_ADDRESS)
                {
                       bootloaderData.currentState = BOOTLOADER_OPEN_DATASTREAM;
                 }
                // else
                {
                   /* User reset address is not erased. Start program. */
                  //  bootloaderData.currentState = BOOTLOADER_ENTER_APPLICATION;
                 }
             break;
          }

After doing these changes my boot loader application state is not exceeding from BOOTLOADER_WAIT_FOR_HOST_ENABLE.
Any suggestion will be most welcome and thankful. please do.


Note : Hardware is working well with sdcard_msd_fat_multi_disk application. so i don't think there is any hardware configuration issue.

Thanks & Regards,
SunilP
