Andy, Thanks for the quick reply. Thanks to your comments, I noticed the two 'bin' subdirectories under the two different 'arm-unknown-linux-gnu' folders, each...
From a suggestion by Brian, I tried the same command but with verbose response: "arm-unknown-linux-gnu-gcc-3.3.4 -v -Wall -o hello hello.c" The response (sorry...
When I power on the 7800, I get the "Booting from onboard NAND flash..." message and then it sits there forever. If I boot from sd card, the board boots up,...
... Having two different 'arm-unknown-linux-gnu' folders is confusing to me too and I'm not a novice - then again I'm a novice when it comes to crosstools -...
... The procedure for doing this is documented here: http://www.embeddedarm.com/epc/fastboot.htm Note that once you set up the 7260 to boot from the SD card...
Ok, Kind of back up now. I can open ttyS3 ok now, but S4 etc was still failing. I copied up the latest tsuart1 and tsuart7800 modules and now each of uarts...
... Well if you start with "mknod /dev/ttyS3 c 234 1" then there is no ttyS2. Maybe that should be "mknod /dev/ttyS2 c 234 1", and then "mknod /dev/ttyS3 c 234...
ok, Got a little confused previously when mknod /dev/ttyS3 was used for the first ts port, and made me think that perhaps the 3rd port was CPU based. Is there...
... Well it is a little confusing because the first two TS-UARTs are actually on the flow control pins for COM1 and 2. The third TS-UART is actually on the...
Thanks for that Things seem to be working except for anything on COM3 - the port opens ok and sets the baudrate etc, but I never seem to get anything on the ...
Hi, I'm hoping someone out there has some thoughts or suggestions that can help me with a problem I'm having. I'm using a TS7260 connected to 2 multi port...
Mike I'm not familiar with the 7260, but have done some timing critical serial code on the 7250. I was getting problems with missing recieve characters. I...
Hi, off the cuff... You don't show how you read/write to the device. Are you sure you are not doing some flushing before reading? A fast return might get data...
I have a TS-7800 with metal enclosure with COM1/COM2/COM3 marked at rear of the box. I supposed that COM1 is /dev/ttyS0 and COM2 is /dev/ttyS1 and so on. I...
These are all good questions. Also, you might try select() as a way to see if data is available. I've had good luck with that approach on a TS-7200. My TTY...

Well 2 things comme to my mind. First the com3 is not /dev/TTYSo (o as oscar) but /dev/ttyTS0 (zero) that's for one, and for the second port com1, did you...
