I have a Teensy 4.1 at a remote site. I wish to update its firmware but due to its location, it is not practical to update its firmware using a PC.
Is there a way to upload an updated HEX file to that Teensy either by connecting it to another Teensy or from a microSD card inserted in the target T4.1?
I did read the following threads but they do not offer a clear solution or a complete sketch:

Thanks in advance for the community's help.
