If anybody is willing, I would greatly appreciate some help, please.
I am trying to use the serial blaster program to boot my TS-7260 and
fix the bootrom. I was following the instructions found in a previous
message:
Message #5312 of 7366
Re: Wrong bootcode
I managed to fix my TS7260 after vaguely following the instructions
from Tom Hansen in message #3553. Not sure if its be best or proper
way but it worked for me:
1) download the eeprom file for the 7260 from
ftp://ftp.embeddedarm.com/images/preboot/ts7260-default
2) download the bootrom image from
ftp://ftp.embeddedarm.com/images/tsbootrom/ts7260-32-default
3) download the redboot image from
ftp://ftp.embeddedarm.com/images/redboot/ts7260-32-kernel
4) compile serial_blaster_1.0 as per instructions and run it
5) boot the TS7260 with JP1, JP2 and JP3 installed
6) once the system has gotten into redboot over the serial link
ignore the 'checksum' message and start minicom and load the
eeprom image to the ram on the TS7260 with
RedBoot>load -v -r -b 0x00200000 -m xmodem
7) copy the 2k eeprom image file with xmodem
8) copy the eeprom image to the eeprom
RedBoot>eeprom_write -b 0x00200000 -o 0 -l 2048
9) load the bootrom image to the TS7260 with
RedBoot>load -v -r -b 0x00200000 -m xmodem
10) copy the bootrom image file with xmodem
11) write the bootrom image to the FLASH memory on the TS7260
RedBoot>fis write -f 0x60000000 -b 0x00200000 -l 0x4000
12) load the redboot image to the TS7260 with
RedBoot>load -v -r -b 0x00200000 -m xmodem
13) copy the redboot image file with xmodem
14) write the redboot image to the FLASH memory on the TS7260
RedBoot>fis write -f 0x61D04000 -b 0x00200000 -l 0x40000
15) turn off, remove JP1 and reboot
I take no responsibility if it don't work or if it mucks up
your TS7260. thanks to Tom Hansen, Curtis Monroe and the others
who posted on this topic
Cheers

I can run serial blaster and it will boot up the board but I get a
"... waiting for BOOTP information"
and it times out after ten seconds. But after this, I can run minicom
and it will finish outputting some information.
RedBoot(tm) bootstrap and debug environment [ROMRAM]

here] available

It gives me that RedBoot prompt which is what I want, but I can't do
anything with it. I cannot enter any commands and it will not echo
any text. I'm not sure what is wrong with it. Is there anyone who
has any experience with this willing to help me out? I would greatly
appreciate any help you can provide.
Things to note: I am connecting using minicom with comm parameters
115200 8N1. I also noticed in the README of serial_blaster some
stuff about downloading the ecos-src and patching it for the ts7250.
I did not perform this part because the file
ftp://ftp.embeddedarm.com/ecos-src.tar.gz is no longer there, and also
the serial_blaster download came with a redboot.bin file already. I
just used that one and it seemed to get me fairly far.
Again, if anyone has any advice please share with me. And feel free
to call me out on anything stupid or completely off the wall that I am
doing.
