uboot2018.03在imx280上移植问题

[zhangxiaobo]

本人自己参考imx280-evk公版设计了自己的开发板，DUART的RX引脚和TX引脚连接在GPIO3_2和GPIO3_3,在移植uboot2018.03编译完成后，使用MFGtools工具烧写后，复位后，系统可以进入uboot，可以显示uboot相关信息，但是无法输入命令，是什么问题引起的该问题？

谢谢你的回答。

Dear Xiaobo,

     The final version of linux BSP for i.MX28EVK is L2.6.35, See here, please!

--Embedded Linux for i.MX Applications Processors | NXP

• i.MX28 Linux 2.6.35 Source Code Files and documentation^{(REV L2.6.35_1.1.0)}

i.MX28's linux BSP source code can also be found in other versions of linux BSP, but we didn't test and validate it. If users want to use other version of BSP, she will have to test and debug it.

In addition, according to your descriptions, the issue seemed not caused by u-boot. The reason why you can't input command should be caused by the setting of terminal software, so you can check if you set CTS & RTS in the terminal.

if yes, don't select it.

Hope above advice can help you!

Have a nice day!

Best Regards,

Weidong
