TI PLT-SU1 拆机+开机照
传说中的vernier…… 这些东西也敢随便拆啊。。。。。。 Thank you so much for the photos of a so rare prototype, maybe the last in the world! ;)
Would it be possible to have photos of the prototype inside its case, in order to see the connectivity and the different extension slots?
Thanks.
By the way, you seem to have lots of uncommon things! ;)
TI-Navigator access point, TI-Nspire CX Navigator adapter, Vernier sensors - congratulations! :D critor 发表于 2013-2-14 13:56 static/image/common/back.gif

Would it ...
The TI-Navigator and Vernier sensors are not mine. They are samples from the TI Agency in Shanghai :P
And.. what does "inside the case" mean? I think I did upload some photos of the inside. Hi,
No sorry, I would have liked to have a look at the case from the outside, espacially for the connectivity.
Critor 机器竟然是类unix 如何验证？ 以下是外观图。
不愧是工程机，PCB上还有不少修修补补的痕迹。 Nice, what's the Serial number on the sticker? :) adriweb 发表于 2013-2-22 00:05

Hi guys,
After a whole year digging into Toto, we've finally achieved some interesting things.
Toto has no keyboard and its few keys let you input only 8 characters.
But the above prompt we're getting is U-Boot.
And U-Boot has a serial USB console, which can be used to input characters.
You just need to setup the /dev/ttyUSB0 device with the 'usbserial' driver on a Linux computer.
The 'help' and 'version' commands then definately prove it's U-Boot:
root@debian:/home/critor# echo help > /dev/ttyUSB0
h
? - alias for 'help'
autoscr - run script from memory
base - print or set address offset
bdinfo- print Board Info structure
boot - boot default, i.e., run 'bootcmd'
bootd - boot default, i.e., run 'bootcmd'
bootm - boot application image from memory
bootp - boot image via network using BootP/TFTP protocol
chpart- change active partition
cmp - memory compare
coninfo - print console devices and informations
cp - memory copy
crc32 - checksum calculation
deregister - Remove an I/O device from use
dhcp - invoke DHCP client to obtain IP/boot params
echo - echo args to console
erase - erase FLASH memory
fatinfo - print information about filesystem
fatload - load binary file from a dos filesystem
fatls - list files in a directory (default /)
flinfo- print FLASH memory information
fsinfo- print information about filesystems
fsload- load binary file from a filesystem image
go - start application at address 'addr'
help - print online help
iminfo- print header information for application image
imls - list all images found in flash
loadb - load binary file over serial line (kermit mode)
loads - load S-Record file over serial line
loop - infinite loop on address range
ls - list files in a directory (default /)
md - memory display
mm - memory modify (auto-incrementing)
mmcinit - init mmc card
mtest - simple RAM test
mw - memory write (fill)
nand - NAND sub-system
nboot - boot from NAND device
nm - memory modify (constant address)
printenv- print environment variables
protect - enable or disable FLASH write protection
rarpboot- boot image via network using RARP/TFTP protocol
register - Register an I/O device for use
reset - Perform RESET of the CPU
run - run commands in an environment variable
saveenv - save environment variables to persistent storage
setenv- set environment variables
setslink - select device to use for loadb/loads transfers
sleep - delay execution for some time
tftpboot- boot image via network using TFTP protocol
tiboot- boot linux uImage or zImage kernel in a jffs2 partition on Toto board
tidiag- perform Toto board diagnostics
tiinstallos- install OS to Toto board NAND flash
version - print monitor version
omap_toto #
root@debian:/home/critor# echo version > /dev/ttyUSB0
U-Boot 1.0.0 (Jan 13 2004 - 15:33:07)
omap_toto #
root@debian:/home/critor#
Note that some commands are undocumented, because they've been added by TI:
- tidiag
- tiinstallos
- tiboot
The 'tidiag' command does launch the diagnostic software, and definately proves us that Toto has a color screen.Watch it for the first time on the Internet : ;)

The 'tiboot' command does start a "MontaVista Linux", but unfortunately it does end up with some filesystem errors and a "Kernel panic" {:13_322:}

But good news - both NOR and NAND chips have now been dumped thanks to U-Boot commands:
Toto NOR chip - 512KB (with U-Boot)
Toto NAND chip - first 2MB (with MontaVista Linux)
(the reste of the 32MB NAND chip seemed to only return 0xFF bytes)

Thank you very much for trusting us - thanks to you, Toto is now saved and safe.{:13_324:}
And please tell us if you ever find another Toto unit, as the 'tiboot' command may reveal a working MontaVista Linux on the difference ;)
