RT1052

[Zz1han]

用RT1052开发板（A1版）烧录程序，用JLINK进行调试，在烧录程序成功几次之后就烧录不进去了（使用qspiflash），用JFLASH进行连接，能连上主控芯片但是无法擦除程序，会弹出如图1提示.用NXP-MCUBootUtility刷FLASH，采用直接启动的方式，在调整好拨码之后，connect的时候会检测不到接口。

Hi,
感谢回复。
你的两块板子都是在Jlink烧录出现了类似的问题，你有试过板载的OpenSDA调试过吗？而且将boot mode设置为Serial Downloader模式，看看能否进入Debug.
Have a great day,

Hi，
非常感谢使用NXP产品，很高兴为你提供技术支持！
请介绍一下在出现上述问题之前，你对EVK开发板做了哪些测试？
我建议你换个接口与NXP-MCUBootUtility再重新连接一下，如何还是连接失败，请分享一下log记录。
Have a great day,

RT1052的这块开发板一直用来跑一些例程做学习使用，一直以来用SDK都正常，然后就正常用JLINK烧录会无法烧录程序，一开始怀疑是FLASH的问题，因为能连上JFLASH但是无法擦除程序，然后更换了相同型号的flash，依然无法烧录程序，电源依次测试下来都正常，包括FLASH的每一个引脚，然后改变电路换用QSPIFLASH(1052默认HYPERFLASH)，依然烧录程序烧不进去，但是各引脚测下来电压都正确，然后更换回HYPERFLASH，使用NXP-MCUBootUtility，连接J9，点击reconnect会有如图1提示框，图2为操作记录，根据你回复的换一个接口连接NXP-MCUBootUtility，我连接了J10,会检测不到连接口，无法点击reconnect。
