I don't see why not. You could almost certainly use the same toolchain. As I
say below, it's a 2.6.24 kernel, gcc 4.3, libc 2.7.

Not for the kernel console. You could modify the fastboot environment to load
USB modules and run a getty on it, but you wouldn't get console messages I
don't think.

I've got one and it's giving me some grief. We were using the TS7250 on stock
kernel/busybox and were attracted to the TS7500 for its potentially lower
price. Unfortunately, with the new enclosure TS-ENC750, and daughter board
TS752A which provides a serial port, DIO and 3 mains relays, the price is more
than the TS7250 + TS-ENC720. But if we can do without the enclosure and
daughter board, it will be cheaper.
The available documentation and software is non-existent. I am going to have a
go at TS once I have got all my questions together.
The thing giving me most grief is the MicroSD card. I have a cheap/crappy USB
to MicroSD reader that just doesn't work, so i bought the MicroSD card and
reader from TS for $55, and they didn't ship the USB reader. Their mistake,
they admit, which they are rectifying, but it takes a week or two for stuff to
arrive from the states to the UK.
I can at least boot the MicroSD card now. The default busybox fastboot
environment doesn't have a working telnetd, so the only access to the card was
over the serial port.
The FAT32 partition on the 2GB Microsd card is described as containing
"out-of-the-box ECLIPSE IDE with debugging, ARM tool chain, Debian Linux
filesystem, documentation and further binaries/utilities"
This is misleading. The ARM tool chain supplied is
crosstool-linux-gcc-3.3.4-glibc-2.3.2-0.28rc39.tar.bz2 which I doubt very much
was used to build the supplied system, which is a 2.6.24 kernel with gcc 4.3
and libc 2.7.
There are several directories on the filesystem which look tempting, for
example samples, sources, docs, distributions, binaries. Until you find they
are empty.
The FTP directory for the TS7500 is almost empty as well.
I will have to move the TS7500 off my critical path and wait for TS to provide
documentation and software.
As I said, when I have had a bit more time to play around, I'll be expecting
direct support from TS on these issues. If they had released more
documentation and software, they might receive rather less support queries.
Oh yes, the power supply is a bit problematic. Without the enclosure and
TS752A support board, the only way to get power in is via the USB Device
connector, which is a standard USB B socket. But I can't find a power supply
with this socket - there are ones with mini USB, but not plain old clunky B
USB. Buying proper USB cables and cutting them up is a waste of money and
will look like a bodge.
