I'm having a small issue with a Gateworks GW2348-4 [1] ixp4xx board. I |
2 |
attached the RXD, TXD, and GND lines from an FTDI USB serial TTL cable |
3 |
to the appropriate JTAG pins (RXD, TXD, GND). |
4 |
|
5 |
I can see the bootup messages in minicom, both RedBoot and Linux. It |
6 |
dumps me to a command prompt, but that's it. The errors I see are: |
7 |
|
8 |
1.) CTRL-C to RedBoot yields periods and doesn't stop the boot process. |
9 |
2.) what I type echoes back, but hitting Enter goes to the beginning of |
10 |
the line, and doesn't go down a line. |
11 |
3.) no response to any commands eg 'ls<CR>' does not give me a list of |
12 |
directories... |
13 |
4.) I do have Local Echo turned off, so I'm reasonably confident that |
14 |
the characters I'm seeing are being seen by the board and echoed back. |
15 |
I tried passing minicom '-7' or '-8' with no improvement. I did get a |
16 |
chinese character for CTRL-C with '-8' as opposed to a period in RedBoot. |
17 |
5.) I managed to catch the 2sec window to telnet into redboot and load |
18 |
my own kernel and rootfs to ram, and execute, but I get the exact same |
19 |
effects. |
20 |
6.) The exact same cable, minicom, kernel, and rootfs (made with |
21 |
crossdev/xmerge/xkmake for the OT! criers :-) ) works fine when booted |
22 |
on an NSLU2... |
23 |
|
24 |
Any terminal gurus here have any idea what I messed up? |
25 |
|
26 |
btw - minicom is set to 115200, 8n1, no HW flow, no SW flow. RedBoot |
27 |
and the first linux are factory loads. |
