最关键那一段没有截取到呀，我要看出厂固件版本，请进入串口窗口后在掉电上电重启，再截取 log
刚才从官方固件地址下载固件文件后，全部分区做了升级，板子启动串口没有任何输出了。
请问这怎么处理？ 正常升级的话串口不会没有输出，请试试能否正常进入升级模式，如果不可以需要进入 Maskrom 模式抢救。
1. 如果版本比较新的板子，通过短路表面预留的两个焊盘，重新上电就可以进入 Maskrom 重新升级了。如果不行请尝试需要如附件所示位置飞线然后短接地，然后重新上电，就可以进入 Maskrom
2. 如果上述方法都不行，或者不具备条件，可以寄回检测，如果只是烧错 loader 导致的寄回重新刷出厂固件就可以恢复了 板蓝根 发表于 2021-6-7 22:10

升级之前要先擦除flash？这一步是必须的吗？ Eric.Z 发表于 2021-6-7 22:43

重来没有说过必须擦除，Maskrom 只是防止设备因为不当操作变砖的最后抢救方法 Mounting /dev/mmcblk0p8(ext2) on /userdata
