Any key presses result in similar garbage.
That vaguely looks like gdb gibberish maybe?
Spot on, this is the GDB remote procotol. The above means:
"Trapped on signal 0x0a, PC=0xc0368134, SP=0xc07f9548"
(the bytes in the GDB protocol are hex strings in target byte order i.e.
Ah-ha ... well, that would explain what I am seeing!
To answer some more of Simon's questions:
That vaguely looks like gdb gibberish maybe? Is the entry point
same/similar for your 3.99.mumble kernel?
Well, the _address_ is certainly the same; I checked that. Although my
3.99.mumble kernel is a gzimg kernel that runs out of flash.
Out of curiosity, does the 4.0.1 normal TS7200 kernel at least load and
start normally? You mentioned that a 3.99.mumble works, but I didn't
see if you'd mention that a 4.0.1 non-INSTALL kernel worked.
I forgot to mention that; a non-INSTALL kernel does work. Under the same
circumstances as well; I load it in via tftp and do "go".
Signal 10 is bus error in NetBSD -- I assume also in the RedBoot GDB stub?
Hrm. So, if I were to connect to this via gdb, would it work? I ask because
it's likely the RedBoot gdb stub and not NetBSD's, and I only have limited
experience using gdb to debug stuff remotely.
I'm not sure what the difference is with the kernels built for flash
When I looked at it, they were just compressed and had a gunzip stub so they
would fit into the flash.
