Re: NetBSD 5.0.1 Support for the TS7200

[Patrick Collins <normalbloke%gmail.com@localhost>]

Ken,

I am intending to build a system to monitor the health of my boat using the TS-7200 and the TS-GSM1. I want the TS-7200 to monitor battery voltages using the onboard ADC and to monitor security and a bilge float switch and a few other things using the onboard DIO. I will use a USB connected GPS receiver to monitor position so that I will know if the boat is on the move when it shouldn't be (stolen or slipped it's mooring or anchor). I will use the TS-GSM1 to send alerts if something is abnormal. I am going to use TCL to glue all this together because it my absolutely favourite programming language. If this is all successful then I will make some more for my yachting friends and then maybe sell some as well.

To get started I want to build a development environment so that I can build TS-7200 kernels. At this point I have a cross development environment running on a IA64 VMware virtual. I can build the standard TS7200 kernel in the 5.0.1 source tree but I can't work out how to gzip it so that it can be written to and booted from the TS-7200 flash.

If you can help me with the following things I would be very thankful:

1.    How to build a TS-7200 gzipped kernel.

2.    A kernel config file that will built a kernel for an 8 MB flash / 32 MB RAM TS-7200.

3.    Any pointer you may have that will help me to build a kernel driver for the onboard ADC hardware and use it with TCL.

Thankyou.

You probably don't want to build ON the TS7200, because it's not the fastest
machine out there.

NetBSD actually has a pretty good cross-compilation environment.  Check
out the build.sh script at the top-level of the NetBSD sources.

5.0.1 has support for the extra DIO boards that are sold for the TS7200;
if you want support for the on-board DIO pins then that support is in
-current, and I have back-ported it to 5.0.1; contact me for more info.

There is currently no support for any of the ADIO hardware for the
TS7200; I have been meaning to write some, but I haven't figured out
what the API should look like.

If you're cross-compiling from MacOS X, you will need some changes;
you can ask me for those.
