[ts-7000] Re: USB not working after serial_blaster/7250

["gkwicker" <>]

Thanks Curtis, I've tried this but now I get the following whenever I 
try to boot the board:

>> TS-NANDBOOT, Rev 1.00 - built 10:14:31, Mar  7 2005
>> Copyright (C) 2004, Technologic Systems
$T0a0f:08003000;0d:00510180;#13

>> TS-NANDBOOT, Rev 1.00 - built 10:14:31, Mar  7 2005
>> Copyright (C) 2004, Technologic Systems
$T0a0f:08003000;0d:00510180;#13

(...repeats indefinitely...)

Here are the steps I took:

1) Used serial_blaster to boot the board with the serial_blaster 
redboot image.

2) Downloaded the following images from ftp.embeddedarm.com:

preboot/ts7250-default
redboot/ts7250-32-kernel

My board is a TS-7250 with 32MB RAM and 32MB flash, so I'm guessing 
these are the right images.

3) After serial_blaster completes, connect teraterm and:

RedBoot> load -v -r -b %{FREEMEMLO} -m xmodem

4) Send ts7250-32-kernel image using xmodem to the board.

5) Write the redboot image to flash and prepare to receive the EEPROM 
image:

RedBoot> fis create RedBoot -b %{FREEMEMLO} -l 0x40000

[...answer 'y' at prompt...]

RedBoot> load -v -r -b %{FREEMEMLO} -l 2048

6) Send ts7250-default preboot image using xmodem to the board.

7) Write the preboot image to EEPROM:

eeprom_write -b %{FREEMEMLO} -o 0 -l 2048

I then remove the JP1 jumper and reboot.  After that, it just 
continuously reboots, printing the message I listed at the top of 
this post.

I tried some other preboot and redboot images from the embeddedarm 
ftp site, but I get the same result with all of them.  I also tried 
these images:

preboot/ts7250-nand2k-default
redboot/ts7250-32-kernel-ts10

Any ideas?  Has anyone successfully restored a TS-7250 to its factory 
default loads of preboot/redboot using serial_blaster?  If so, which 
images and procedure did you follow?  Thanks in advance for your 
help...

Cheers
