Howto apply realtime patch to kernel
by Hiram.Coffy
::
Rate this Message:
I have an OEM product that uses your Basix 400-xm-bt motherboard. It is running the 2.6.21-r1 kernel. I need to apply the -rt8 patch to support real-time Java. What do I have to do? I am thinking of Sun's RTSJ based api. For the base Java SDK, I am assuming that any of the recommended J2SE 1.5 stacks from your website would do the trick. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.

robostix baud rate

Rate this Message:
Hi,
I'm using the robostix Flash-LED program. It says the baud rate should be 38400 8n1 but that output is giving me garbage. Any ideas on what I'm doing wrong? ~Shane ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.

I was using a poorly made usb-rs232 converter. When I use the actual
rs232 converter the program works fine. On Tue, 20 May 2008 12:00:14 -0600 "Shane Kirkbride" <skirkbri@...> wrote: > Hi, > I'm using the robostix Flash-LED program.

tweener board to robostix issues
by Shane Kirkbride
::
Rate this Message:
Hi,
Now I am trying to use the Flash-LED program and get UART out on the tweener board. I made the correct modifications to the tweener board and plugged it in. It's not outputting anything. I changed the uart from u0 to u1 in the code and back there was no change. Does anyone have any ideas of how I can get the tweener board to work with Flash-LED.c? Thanks. ~Shane On Tue, 20 May 2008 12:08:44 -0600 "Shane Kirkbride" <skirkbri@...> wrote: > I was using a poorly made usb-rs232 converter.

The tweener board exposes the console of the gumstix (FFUART). By default UART-0 and UART-1 on the robostix aren't connected to anything on the gumstix. You can hook up a logic-level to RS-232 adapter and see the output on your host machine. You can connect them to the STUART port, and then write a program which runs on the gumstix and reads the STUART port and prints the output to the console. sertest is a program which can do this. You can connect UART-0 to STUART by using two jumpers as shown on this page: <http://docswiki.gumstix.com/Robostix_gumstix_ISP> -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.

Thanks for getting back so quickly. I am only using the robostix and an
STK500 to program it. (I don't even have a gumstix board) I've mounted the 'tweener' board on the robostix board and then connected the tweener to the output. I've downloaded Flash-LED.hex to the robostix, I know it is running because the LEDs are flashing. However when I try to read the outputs from the UART0 I get garbage. I would like to use the tweener board for I/O from the keyboard, but I cannot. Also, my robostix and tweener looks very different from the one in the link.

The tweener was never intended to be used with a standalone robostix. The data coming out on the UART-0 pins is logic-level serial. You'll need a serial adapter like the one of the ones on this page: <http://docswiki.gumstix.com/Serial_adapters> in order to see the data on your PC. Also, be sure to read this page: <http://docswiki.gumstix.com/Serial_voltages> to understand the differences between the various voltage levels. -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.

Ahhhh - there are RS-232 to logic-level voltage converters included on the STK-500, so you should be able to use one of those. -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.

If all you want to do is add the patch to the build process, reconfigure the defconfig and build the OE kernel, there's lots of tutorials to do this. The most recent can be found in the post under the subject "Kernel Hacking" started on 5/20 at 2:13pm. Basically, it involves copying the kernel setup to the user.collection directory and working with the recipe and config there. That should allow you to build a kernel to support what you want as long as it generically fits the OE setup. -- Pete Funny=Truth Truth=Beauty So take it as a complement when people say you look Funny. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
