What file transfer protocol do I use when sending an S-record file when I issue the loads command ?
There is no protoco. You just send line by line...
I tried with both TerraTerm and Hyperterminal.
Why did you not follow the description in the Manual?
In both these cases, it reads the first line correctly, but by the time it wants to process the following line, it ends up reading garbage. It looks like the terminal programs kept sending bytes while U-boot was processing the first S-record line (which is an S0 record).
Yes. With other terminal emulation programs you may have to twiddle with inter-character and especially inter-line timings.
I also tried sending a file with the protocols Xmodem, Ymodem, Kermit.
loads is not supposed to support xmodem or ymodem or kermit (binary) protocols.
For ymoden, please use the loady command.
For kermit binary protocol, please use the loadb command (recommended: most stable and often fastest of the serial protocols).
