Extending the IVOS Kernel

After booting the kernel the IVOS extensions may be downloaded, that is, send it as a plain text file through the terminal. If it's a bare kernel then you may want to download the decompiler and then the SDFAT16 driver after which you can type "0 BURN". The zero "0" tells the O/S to find the next available Flash area and burn the application there with an auto-link appended to the end. Don't forget the white-spaces, they separate numbers and words, you may use multiple spaces or tabs.

The burning to Flash is optional and usually only performed when the code has been debugged.
