使用RK的firefly版本的linux SDK,地址见http://opensource.rock-chips.com/wiki_Uboot
For firefly-rk3288 board. Use below command to build the U-Boot:
./make.sh firefly-rk3288
加载后可正常启动,但是怎么都进入不了loader烧录模式,串口log如下:
U-Boot 2017.09-01495-g3a06149 (May 16 2018 - 15:55:01 +0800)

### ERROR ### Please RESET the board ###
跟踪代码是udc_enable的时候hang()了,原因不明,应该是uboot有bug,请问如何解决?多谢! |
