am5728支持串口启动,我使用的串口终端工具是picocom,串口参数115200-8e1
TI官方人员给出3步:
1. Perform binary transfer of the boot message: 0xF0030002 -> this tells the board that you will transfer a boot image.
2. Perform binary transfer of u-boot-spl.bin
3. Perform xmodem transfer of the u-boot image
请问我应该如何操作?
万能答案:
要供应商提供样例啊!
你付钱卖硬件还不要服务,太傻了吧!
