I tried to update the WHD firmware on the Edgi-talk board. But msh CLI didn't work in the XiaoZhi example:
But when I tried to copy and paste "whd_res_download whd_firmware", msh CLI got scrambled text as command.
Build environment:
RT-Thread IDE 2.3.0 and BSP 1.2.1.
XShell 8 for terminal
I have screenshot but can not upload into this post.
This looks like a terminal/paste encoding issue rather than an RT-Thread problem.
Try:
Set XShell to UTF-8 encoding
Disable “smart/fast paste” options
Test with another terminal (PuTTY / Tera Term)
Paste into a plain text editor first to remove hidden characters
Since help works but pasted commands break, it’s very likely extra hidden characters are being added during paste.
