Dear Rupesh,

The discussion is about usage of S-Record files for Downloads instead of Binary file. Generally S-Record Downloads are used when the medium of communication is Serial Port , which has no Error Checking mechanism inbuilt in hardware.
...or which may be not 8-bit clean so binary transmission is impossible.
Whereas when we consider the Network download throgh Ethernet, most bootloaders (u-boot as well) does a binary download. Is this because the Ethernet hardware has a Error Checking mechanism inbuilt ?
This is one of the reasons. We also use binary protocols (like kermit binary protocol with the "loadb" command) over serrial lines.
If yes, even using a USB hardware for download also can use Binary instead of S-Records??
Define "a USB hardware"... A mass storage device? A communications device? A network device?
Please comment on my arguments?
S-Records is a very simple protocol, which is easy to implement with relatively small memory footprint, so it is usable even on small micros where you could only dream of things like ethernet or USB host functions.
