Thanks for the picture. It confirmed what I thought was the serial port.
I made some progress, but now I'm stuck. I'm using cu with MacOS and an FTDI adapter. As you suggested, I connected the serial first and then pressed the reset button. A bunch of messages were displayed in Terminal.
I hit a few keys during the output, but at the end, it hangs with these messsages:
Code:
yaffs: auto selecting yaffs2
VFS: Mounted root (yaffs filesystem).
Freeing init memory: 96K
Warning: unable to open an initial console.
Failed to execute /linuxrc. Attempting defaults...
SBZ: try run /sbin/init
SBZ: try run /etc/init
SBZ: try run /bin/init
SBZ: try run /bin/sh
Kernel panic - not syncing: No init found. Try passing init= option to kernel.
The complete log is attached.
I tried resetting a few more times with the same results.
Any suggestions on what to try next?
