# Some info about Ctera firmware:
|
|
# 1. It's simple tar file (GNU standard), but it must have ".firm" suffix.
|
|
# 2. It contains two images: kernel and romdisk. Both are required.
|
|
# 3. Every image has header and trailer file.
|
|
# 4. The struct of tar firmware is: header kernel trailer header romdisk trailer
|
|
# 5. In header file are some strings used to describe image. It was decoded from
|
|
# factory image.
|
|
# 6. Version format in header file is restricted by Original FW.
|
|
# 7. Trailer file contains MD5 sum string of header and image file.
|
|
# 8. Firmware file must have <=24MB size.
