自己画的板子，用了T113-S3,镜像也编译了，但是卡在烧录界面不动，求大佬帮助

[planA8]

驱动装好了，电脑也可以识别设备，上电自动开始烧录，但是一直卡在0%界面不动，原理图上看到芯片的USB_FEL引脚和GND连接了，上电之后应该会自动置低电平板子进入烧录模式，然后我给板子上电之后软件也会自动进入烧录界面，我短接RESET和GND给置低电平也是烧录失败!目前只能编译成功USB烧录的镜像，编译SD卡的镜像会打包失败和编译报错。板子上设计了SD NAND。84616ae6-f4b9-4470-8b77-8587f4d57b18-2e12ab43ae1fe52d327d0004f9832d73.png

接上串口看看日志，0%多见于卡ddr初始化

@awwwwa 方便问一下您用什么软件看日志吗
