[U-Boot-Users] Loading U-Boot SREC file

[U-Boot-Users] Loading U-Boot SREC file

[Devraj Mukherjee]

Hi everyone,

Thanks to everyone who responded to my email. I managed to get a version 
of UBoot compiled for our target board and have ended up with an SREC file.

The boot loader that already exists on the board allows me to load the 
SREC file via TFTP, and I have succeeded doing that. I am still unsure 
if we should go ahead burn the image and restart the board to see UBoot 
come up.

If there is anyone out there using a LH7A400 based board then please let 
me know if I should look out for anything else. Any other suggestions 
are very welcome.

Regards,
Devraj

I am not familiar with your platform but the SREC file is definitely
not for tftp download.  You will end up with the SREC file in memory -
uninterpreted.  If you use tftp, then use the bin file - the srec
format is for serial download only.

Cheers

This is not quite correct. There are  so-called  boot  loaders  (like
YAMON,  to  name  one) that are stupid enough to accept ONLY S-record
files over TFTP. [If you feed them a binary image  this  may  produce
some funny console error messages and/or completely hang the system.]

[Don't try it out on "charon", please ;-) ]

Best regards,
