Prerequisites
- Email syscom@csclub.uwaterloo.ca asking to be added to the board group.
- An ARM compiler and build environment. If you do your development on corn-syrup this is already set up for you.
- Basic working knowledge of GNU screen.
Compiling and Running Your First Program
We have modified the busy-wait I/O library used by CS 452 to work with the TS-7800. The following steps explain how to compile and run the test application on the TS-7800. These steps should be completed on corn-syrup.
- Clone the test git repository from csclub.uwaterloo.ca:/srv/git/arm/ts7800-bwio.git:
git clone csclub.uwaterloo.ca:/srv/git/arm/ts7800-bwio.git cd ts7800-bwio
- Build the test application:
make CC=arm-linux-gnueabi-gcc
- Create yourself a directory on our TFTP server (caffeine):
ssh caffeine mkdir -p /srv/tftp/ARM/$USER
- Copy the test application (bin/iotest) to your directory on the TFTP server.
scp bin/iotest caffeine:/srv/tftp/ARM/$USER/
- Run become_board to attach to the TS-7800 screen session.
become_board
- Reboot the board from the radreboot window. Press C-a 1 (control-A, then 1) to switch windows, then press enter to reboot.
- Execute your test program on the board. Press C-a 0 (control-A, then 0) to switch windows. Replace $USER by your user name.
tftp ARM/$USER/iotest bootelf
If all goes well, you should see the following output:
Hello ***Hello Hello world. Well, hello world23. -23 worlds for 1 person. ffffffe9 worlds for 723 people.
If you press any key the board will reboot.
