最近新购买了一批核心板，采用官方的载板进行烧录，使用如上命令，如下是我的运行日志：

Cleaning up...
提示报错might be timeout in USB write，在Sending blob之后，我注意到之后板卡过了大概30s风扇才开始转动，或许进入了某种模式，但此时电脑终端已经报错退出；
我尝试过主机关闭USB自动挂起，可还是解决不了问题。
奇怪的是，我使用之前购买的核心板，而不是这一批购买的，然后使用同样的USB线缆和载板进行同样的命令烧录，在Sending blob之后，板卡风扇立马开始转动，脚本也正常运行，烧录也成功，因此排除了USB线缆和主机以及载板硬件的问题，这似乎是由核心板引起的，使用的都是JetSon ORIN NX 16GB
我也联系过供应商，供应商回复在出厂时已经烧录过系统，我供电后进入查看，确实可以进入系统并且正常工作，证明核心板是正常的并且没有损坏，但就是无法烧录系统。似乎是由于核心板USB接收数据的问题或是由于bootloader的问题，能否帮忙找出故障原因？
