hi ,Rita,考虑可能是硬件问题,MCU摸着比正常烫一点,想进一步定位问题,看看是MCU损坏的个例还是有设计风险。请帮忙分析下,谢谢!
烧录也是通过USB-OTG,使用MFG。问题出在JUMP TO OS IMAGE的环节。
打印信息如下。
打印信息一是其他板卡的正常打印信息,由于我司只能专门的机器使用U盘,在我自己电脑上MCU被识别为U盘后就被禁用,所以打印信息只执行到被识别为大容量存储设备后就停止了。
打印信息二到四是故障板卡的打印信息。该板卡有时启动到BOOTING THE KERNEL后,就再无打印信息;偶发的能继续往下走点,但到某环节后就开始异常(标注红色或粗体)
一、正常板卡打印信息
