Hi Micheal
Thanks for your response.. I hope we can figure this out soon.
(Since I have to wait about a day each time for response since I'm on
the other side of the planet )
I've installed armel Debian linux (etch)
And linking with apt-get to sid and upgraded.
Don't think this should really affect kernel stuff anyway?
I'm booting from on-board flash.
Well I can't exactly tell you the md5sum for ts7800_nand.ko
Because if I say lsmod I don't see any nand driver.
I only have ts7800 and tssdcard drivers so I guess the nand driver is
inside the kernel or something?
I've installed the folllowing kernel to nand flash (dd to /dev/mtdblock1
(I think it's 1))
ftp://ftp.embeddedarm.com/ts-arm-sbc/ts-7800-linux/binaries/ts-kernels/Image-7800-initrdroot
The md5sum of the image:
95605e729333e65f2bb99b4aa2db3621 Image-7800-initrdroot
I've downloaded the following modules package:
ftp://ftp.embeddedarm.com/ts-arm-sbc/ts-7800-linux/binaries/ts-modules/linuxmodules-2.6.21-ts-jan182008.tar.gz
the md5sum for that .tar.gz is:
f299f6c03479a77e723a9bc2d47ab688 linuxmodules-2.6.21-ts-jan182008.tar.gz
I've also updated the following driver to the 21 Jan version:
5799b7ecb79948d11cc4cabfc3d3df7c tsuart7800.ko
From here:
ftp://ftp.embeddedarm.com/ts-arm-sbc/ts-7800-linux/binaries/ts-modules/tsuart7800.ko
I think I've updated tsuart1.ko also but that is still the 18jan version
from the ftp so I think it's the same.
in my /lib/modules/2.6.21-ts/kernel/drivers/mtd/nand folder I have:
560595f538f83bf360aec50a05ca859b ts7800.ko
(on the nand flash itself)
Somebody else said that the nand driver corrupts the flash..
Well I really hope he is wrong.
And so far I have good hope for that as the segfaults or other funny
things seem to disappear after a reboot. So I don't think it's that.
A few other clues I can give you:
Once I had the messages from dmesg (or syslog file) that drivers could
not be registered.
Other times apt-get doesn't give segfault but complains about a wrong
library version or something(was last week so can't remember exactly)
But it all seem rather random. So I don't think the errors are directly
related to the bug/problem.
btw. Is there somewhere an example program which can use these ts-uarts
(8 and 9-bit) using the /dev/tt(t/8)s? devices.
Because it really seems that program like setserial doesn't really
change the settings - which worries me.
Thanks
-Heinrich
