Sorry to say I don't have a fix here, but I have seen the same thing on Gumstix Overo Earth. If I connect through minicom to the console port during boot-up, I get random garbage text mixed into the u-boot text as the system is coming up. Sometimes the text may have "<Interrupt>" or a partial string of the word mixed into the text output. When this happens, the boot sequence freezes and I have to cold boot the board via the reset button on the Summit board. A single reset is usually enough to make it boot properly.
I usually don't connect to the console port when I'm using the board, so I don't know if this garbage text continues on a successful boot, but sometimes when I'm in a terminal, it loses keyboard input completely and I end up cold booting it.
At least you're not alone...
my verdex xlp6 suddenly started spitting out garbage on the serial line.
this was working fine till yesterday, but today for some reason it stopped.
I rarely touch the gumstix or the connections, so i'm very surprised at what
has happened. i figured whatever the reason, the connections must have come
undone and so it's probably missing a few bits here and there leading to
garbage in kermit. However, even after i reconnect, it continues the same
I am able to ssh into the box fine and it is working but for the serial. is
there some way for me to check if some hardware is screwed up? i doubt it's
a software issue because even the bootup sequence from UBOOT is garbled.
Also, i can't seem to type anything back on to the gumstix.
my kermit file is the same (pasted below) and still works with another
embedded board i have (avr).
set line /dev/ttyUSB0
set flow-control none
set carrier-watch off
set speed 115200
set prefixing all
set file type bin
set rec pack 4096
set send pack 4096
set window 5
any clue on what could be happening? has anyone seen something like this
before? i have a demo for my project tomorrow and need uboot to change it to
boot from flash rather than NFS.
