[syslinux] Checking CRC (of bzImage) before loading

[Mau Z]

Hi,

I am wondering how to implement the following customer's requirement :
The system is a stand alone embedded system with no operator (with Linux).
There is one SSD for the system's usage (and that is where the system loads
from).

The requirement is to have a duplication of the Linux Image, and that
syslinux should calculate CRC of "the first image" (say bzImage_1).
If the CRC is correct then load the image, if the CRC is not correct, than
syslinux should try "the other image" (say bzImage_2).
If even that is no good do nothing.

Any suggestions as to how to implement the requirement ?


Thanks
Mau
