Comment 2 Sean Adams 2005-03-29 11:10:47 UTC

This is caused by long TCP timeouts on dropped packets.

Correct solution is to dump the firmware update into SDRAM before copying to flash, rather that writing 
the flash on each TCP segment received.

punting unless we have cases where the update fails altogether.

Comment 4 Kevin Pearsall 2005-08-18 16:43:15 UTC

Ehhh, yeah, I'm not seeing this any more really.  You guys?
