Issue with Enabling CONFIG_NETCONSOLE in Boot-loader

[Ahmed Mokhtar]

Hello Team,

I hope this email finds you well. I'm currently facing an issue with 
enabling the CONFIG_Netconsole flag under the bootloader. Despite 
CONFIG_NETCONSOLE being already enabled in the build system, I'm 
encountering difficulties in getting it to work.

Here's what I've tried so far:

 1. Enabled CONFIG_NETCONSOLE in the build system.
 2. Set the environment variables as follows:
      * |setenv nc 'setenv stdout nc;setenv stdin nc'|
      * |setenv ncip 192.168.1.1|
 3. Saved the environment using |saveenv|.
 4. Executed |run ncc|.

However, I encountered the following errors:

|## Error inserting "stdout" variable, errno=22 ## Error inserting 
"stdin" variable, errno=22 |

Upon checking the environment variables using |printenv|, I see that the 
|stdout|, |stdin|, and |stderr| variables are set to |serial at ff812000|. 
Here's the relevant part of the environment:

|tderr=serial at ff812000 stdin=serial at ff812000 stdout=serial at ff812000 |

I'm seeking your assistance in resolving this issue. Any guidance or 
solutions would be greatly appreciated.

Thank you for your attention to this matter.

Best regards, Ahmed
