I have an application where I'd like to measure the pulse width of a pair of signals about 10 times per second. The pulses are in the range of 2 to 5...
Hi there, I'm working with the 256Mb CF card by booting with exec -c "console=ttyAM0,115200 root=/dev/hda1" and I need to see the on board 6Mb flash memory to...
Hi all, Has anybody gotten the ts-7000 to get its IP address (either wired or wireless) via DHCP? I've gotten both to work statically, but they refuse to use...
... I'm pretty sure the ep93xx uart drivers are using the FIFO's. They are 16bytes wide. The hardware is capable of using DMA, but I don't think Linux...
... Hi, I've got the kernel to boot with the ip=dhcp option in order to get the kernel to boot nfsroot == Executing boot script in 2.000 seconds - enter ^C to...
... create a directory where you will mount the flash memory... cd / mkdir flash then add the following entry to the file /etc/fstab /dev/mtdblock/1 /flash...
... I'm a bit baffled by this? Are you saying the CFDISK won't mount? If the file system on the cfdisk is clean then where does the fsck come in? what does...
I commited my NetBSD TS-7200 port to NetBSD-current over Christmas and have just now put a precompiled installation available from FTP/HTTP for those that...
I took Jesse's advice and wrote my pulse-measurement code as a loadable device driver. However, I get a kernel oops when I try to access either the DIO data...
Those pointers referring to 0x8xxx_xxxx addresses are not valid. the 0x8xxx_xxxx is physical space, and in a driver you're working with kernel virtual space...
Hi all, I am starting a program that uses the DMA controller to store data that is being recieved from the SPI port. I have the SPI part working but I keep...
Has anyone used the watchdog? Any hints or sample code? Perhaps it isn't supported by the kernel, so would my best bet be to mmap the processor registers and...
The watchdog on the EP93xx isn't considered reliable. You can use it, but there is an errata from Cirrus that it may just lock up the board rather than reset...
Thanks that fixed it. Do you have a suggestion for the section of RAM that I should use to write my data to? I need between 1K to 16K of RAM. Thanks ... ...
Any memory should do. Just be sure you understand the L1 cache issues. I'm not sure what it is you're doing, but another thing to keep in mind is that most...
Jesse, This is my first attempt at writing a program using the DMA controller so I am in a learning process with all the registers, etc.. My program writes to...
... As Jesse said, you have another large problem on the horizon, you need to use a physical address when programming the DMA controller, not a virtual address...
Hi all, I am going to attempt to write a driver to access the SSP port in the EP9301 processor. If anyone has example code or information that might help me...
Hi, I am trying to write a driver that will take data from the SSPDR register and store it in a buffer location in SDRAM. Can I use the functions in dma.txt(I...

I'd like to build a couple of standard linux packages like bind and dhcp for the ts-7200. I downloaded the debian source tarballs, but there doesn't seem to...
The crosstools tarball for linux doesn't match up with the system on the CF card. The CF card has: libstdc++.so.3.0.4 and libstdc++-3-libc6.2-2-.10.0 But the...
OK, I was booted on the CF card and I was transferring a file down to the board using rz on the board, and kermit on my laptop. The transfer hung. I could...
Fixed it. Don't know why it just hung there when booting. I popped the CF card into my laptop and fsck'd it. I also mounted it on the laptop and checked it...
Ok, I commited more work for the TS-7200 to NetBSD-current today and was able to write drivers/test existing support for the following new peripherals: *...
We're using the TS-7200 board in a system we're putting together. We have the board up and running OK, but I have a question. We'd like to use the digital I/O...
We currently do not have a driver for GPIO interrupting in Linux as we're not certain what type of interface would be generic enough to be use to userspace...
