We are looking for an http client now as well. Our major issue revolves
around the download times for tftp.
Can Volkmar Uhlig kindly provide the patches?
Our units automically update themselves inside of uboot giving us the most control over our firmware. The issue is that it takes 20 minutes via a DSL line in Africa to update our units. An http test showed that the same firmware downloads in 30 seconds. We have also added things like the blksize parameter to the uboot tftp client to get it down to 20 minutes, our original download times were ~50 minutes.
Hmm -- I'm assuming that is http://www.faqs.org/rfcs/rfc1783.html ?
Do you have a patch to send - or that I can clean up and submit?
Requesting a bigger blocksize is already implemented and should work if the server supports it. It's been a while since I used this, but it was added along with support for multicast TFTP, probably about a year ago.
I see:
#define TFTP_MTU_BLOCKSIZE 1468blksize static unsigned short TftpBlkSizeOption=TFTP_MTU_BLOCKSIZE;
/* try for more effic. blk size */ pkt += sprintf((char *)pkt,"blksize%c%d%c", 0,TftpBlkSizeOption,0);
but that is it...
No CONFIG_ options for anything else?
