libti99-helloscrl

This is a simple helloscrl application in EA5 format suitable from running from Editor/Assembler or calling using call tipi on a metal TI994a with at tipi installed.

Just a plug, if you need a tipi, arcadeshopper was very helpful giving me some pointers and helping me troubleshoot things, so I recommend getting one from his store.

Build Tools Installation

This requires "GCC for TI", libti99, as well as a few other build tools. The best comprehensive directions on how to get a working enviroment are here:

libti99

Depending on your environment, you may have to stop makeinfo from happening. This will fix a breaking part of the build that dies on texinfo. That can be done by setting the following environment variable:

export set MAKEINFO=true

Building the code

1. Edit the Makefile to point to paths for your system.

2. Run make

   mkdir -p objects tms9900-as crt0_ea5.asm -o objects/crt0_ea5.o mkdir -p objects tms9900-gcc -c main.c -std=gnu99 -O2 -Werror --save-temp -I/range/share/software/ti994a/libti99 -DBANK_STACK_SIZE=10 -o objects/main.o mv *.i *.s objects/ tms9900-ld objects/crt0_ea5.o objects/main.o --script=linkfile -L/range/share/software/ti994a/libti99 -lti99 -o helloscrl.elf -Map=mapfile rm -f upper.bin lower.bin objects/HELLOWORL? helloworl?.tfi tms9900-objcopy -O binary -j .text helloscrl.elf upper.bin tms9900-objcopy -O binary -j .data helloscrl.elf lower.bin python ./ea5split.py A000:upper.bin 2000:lower.bin objects/HELLOSCRL ----------------1:1-- filename: objects/HELLOSCRL flag: 0xffff len: 0x7f2 addr: 0xa000 ----------------2:1-- filename: objects/HELLOWORLE flag: 0x0 len: 0x14 addr: 0x2000 xdm99.py -T objects/HELLOWORL? -f PROGRAM for i in helloworl?.tfi; do cp $i basename $i .tfi; done rm -f .DSK xdm99.py HELLOSCRL.DSK --initialize DSDD40T xdm99.py HELLOSCRL.DSK -t -a helloworl? xdm99.py HELLOSCRL.DSK HELLOSCRL: 13 used 1427 free 360 KB 2S/2D 40T 18 S/T

Thanks

Special shout out and thanks to both jedimatt42 and arcadeshopper for giving me some pointers along the way, and, for publishing code that helped me get to a point that things are working. I started with examining TI99-FTP and the example Telenet application from the tipi project to understand the basics of a build enviorment - the Makefile and linkfile in this project are heavily taken from their work.
