TQ2440白屏修复，无法正确读取Nor Flash Id

我买了个TQ2440的开发板，开发板白屏，没有做过什么操作。我最近买了个Jlink想刷下程序，但是Jlink提示如下：如果不选择Flash型号就提示无法connect Flash. 怎么确认Nor Flash坏了没有，还是Nor Flash ID被覆盖了？如何修复？（确认Jlink配置正常）

jlink是从哪里买的，要从我们这边买的才配套哦

不从你们这边买的Jlink还识别不出来这个Flash芯片么？我的Flash 芯片应该是EN29LV160AB吧

你们的Jlink在那个地方订，多少钱，你给我发个链接吧

天嵌的客服呢，这个能不能确认是由于Jlink不配套导致的？能确认的话给个链接吧
