也无法进入loader模式，按recover reset 后打印信息如下：

这个是需要sd卡启动的吗？

作者: sunkai 时间: 2021-3-17 09:07
板子上有一个maskrom按键，可以进入maskrom模式再刷吗？

你好，rk3399prox，就是下面链接的板子

做过擦除flash操作么？
进maskrom烧写可以启动么？

什么板子

新的板子，无法开机，也无法进入loader模式，有一个maskrom按键，不过还没有尝试过，可以尝试进入maskrom模式进行烧录吗？

可以尝试进入maskrom烧写,另外确认下电脑端的usb驱动是安装好,如果还不行换一下电脑端的usb看下能不能正 ...

按照教程下载了驱动，串口有信息，显示出com口了，还需要别的驱动吗？
烧写工具怎么都识别不到板子，长按maskrom，再按resnet还是不行，还有别的方法吗？
