RK3399PRO-JD4固件无法烧写
１．上周五收到了两块rk3399pro-jd4的新主板，一块可以烧写，一块却烧写不了，刷机步骤，方法一：长按recover,然后按一下reset，过段时间松开recover，但是没有进入刷机模式。方法二:想用adb命令进入刷机模式，但是将usb公对公插入ubuntu电脑，设备都识别到，插入windows电脑也没识别到设备,usb线换过３跟，排除了ｕｓｂ线的问题。２．之前问贵司买过几块rk3399pro-jd4板子，其中一块刷了ubuntu固件之前操作都没问题，不知什么原因该板子上周有时候出现开机无法进入系统，有时候进入系统过个４－５分钟鼠标卡主，整个系统都卡住了，固件重新烧写，也是一样的现象，用贵司的hdmi触摸屏也出现一样的现象，想抓debug log 用usb转ttl，波特率1500000，一堆乱码，无法获取log，询问淘宝客服，让我发帖询问。 1、烧写固件时请注意：先用数据线连接开发板的 USB3.0(OTG)接口和电脑，然后再按照你的方法一进入loader模式。如果还是没有进入loader模式，可以按照wiki进入maskrom模式烧录固件： http://wiki.t-firefly.com/zh_CN/Core-3399pro-JD4/maskrom_mode.html
2、串口波特率等相关设置都正确，然而还是出现乱码的话，试试看把 TX/RX 交换看看。详情请参考wiki：http://wiki.t-firefly.com/zh_CN/Core-3399pro-JD4/debug.html
１．第一个问题解决了。
２．第二个问题换了个usb转ttl设备，log能出来，下面是debug抓取的完整log,一直卡在firefly开机log界面

这样的情况是hdmi屏幕卡住了，但是在串口里还可以操作是吗？ hdmi屏幕没卡住的时候，串口可以操作，卡住的时候，串口里也卡住，按回车也没反应，没接hdmi也是一样的现象 我是经常遇到过无线鼠标卡住几秒钟的情况，我一直以为是usb的无线鼠标的问题，没注意是不是内核卡主还是哪里卡住了，一般不接串口 请问接下来怎么操作，这是什么原因导致的，买了几块板，就这块有问题，不知是软件还是硬件问题 flyfish 发表于 2019-12-30 16:39
请问接下来怎么操作，这是什么原因导致的，买了几块板，就这块有问题，不知是软件还是硬件问题
1.如果只有一块有问题可能是硬件问题，烧个android验证一下会不会也是异常
2.如果没有打印任何错误log就挂掉很可能是硬件问题，你可以试一下串口卡住的时候输入"fiq" fiq是优先级最高的终端模式，防止机器卡死时候可以抓取log。
3.如果上诉方法都验证过有问题，就没有办法了，寄回去硬件检查一下吧
