25 Rhetorical Question: How many of those "young kids" are _good_? There
26 is no shortcut to deep understanding (no, I'm no where close).
27 Something a GUI obfuscates away, the cli celebrates. But then, we
28 agree... ;-)

31
32 Are you implying that openocd is a gui? I think you might be referring
33 to something else. Here's a quick and dirty:
34
35 http://openhardware.net/Embedded_ARM/OpenOCD_JTAG/#testocd
36
37 Basically, run openocd from the command line, specifying a config file.
38 Then telnet into it. ;-)
39
40 Someone may have glossed over this with a gui, but that's not what crops
41 up in google.

49 I haven't needed a jtag for it, since the bootloader was sufficient, but
50 I like the NSLU2 as a good starter kit. I recently saw one on ebay for
51 ~$30US. I bought mine new years ago for ~$70US.
52
53 The next step after that (at least, what I did) was the Gateworks 2348-4
54 board. Same processor, 4 mini-pci, 2 ethernet, USB as an option. It's
55 less than $300US. Openocd works with it's parallel jtag programmer. I
56 haven't needed that yet either, since the bootloader works for me.
57
58 The ethernet support is native in the vanilla kernel since about 2.6.21
59 or .23. As of 2.6.27, the kernel has support for the hardware crypto
60 engine. IPsec VPN gateway, anyone?
