Finding some bugs though. Like Wordstar, CLINK is also crashing the zicog, but is working fine on the Altair SIMH.
I wrote a tiny program in Notepad called HELLO.C (see attached)
#include <stdio.h>
main()
{
printf("Hello World\n");
}
Copied it into the SIMH with R HELLO.C
and ran the compiler

Hello World

Downloaded HELLO.C with XMODEMP R HELLO.C as it is quicker than pulling out the sd card. (Note that xmodem by default puts all downloads on drive A, so you need to do a PIP C:=A:HELLO.C to copy it to drive C)
On the triblade, CC.COM works but CLINK crashes after printing the first line - it then prints about 20 copies of the Z80 registers and then hangs. I'm not sure how to debug that sort of thing. But it is a similar crash to the Wordstar crash. Addit - BDS C is apparantly written in 8080 rather than Z80, as (probably) is Wordstar. Not sure if that helps narrowing down the bug. Even more strange is that BDS C and Wordstar were both working fine back in the mid August version of the zicog.
Now that heater has a ram chip...

| Posted 9/16/2009 1:42 PM (GMT -8) | | Sorry about the delay, running the exerciser is an overnight job. It fell over at this point. There is a small chance due to CRLF issues that it may be the instruction after this one.
Not sure how to test this quicker.
Also - maybe there is a file access issue as well - both CLINK and Wordstar start off by reading files off the disk.
Re "In both files ?" - which other file?

| Posted 9/16/2009 3:46 PM (GMT -8) | | Hi All,
I have a question on the SD file structure for zicog_cpm_rc5.5b_rr118 .
Would either you Cluso99 or Dr. A or heater create a batch file script to do the formating and writing of the files on the SD card for the releases?
I realize it is early (pre V1.0 release) but it would help all those of us who are "silently" trying to follow along without waiting to V1.0 .
I believe this sort of script would be helpful if it were part of the package of files in each release to somewhat automate or to give a template for how to automate this process.
Thanks

| Posted 9/16/2009 7:42 PM (GMT -8) | | Dr_A: I see the problem here.
The test "aluop a,<ixh,ixl,iyh,iyl>.....(376,832) cycles" is testing instructions like "ld a, xh", "ld a, xl" etc. Where "xl" is the low byte of the X register etc.
Just so happens that ZiCog does not implement those instruction !!!
Why not you might ask?
Well those instructions do not exist in my MOSTEK Z80 Technical Manual or my Zilog Z80 Family Users Manual. I'm not sure why EXZ80DOC is testing them.
But this gets more serious and weird. There is a bunch of instructions that use an index register plus an offset e.g. "LD r,(IX + d)" which we also do not implement.
Turns out these are in my Z80 documents but in this case EXZ80DOC doe not test them.
This will take a little research to sort out. Seems my original op-code list was a bit off.
Mean while, actually why not set CPU_8080 when building ZiCog. WordStar and BDSC should detect a 8080 and behave correctly. N.B. EX8080 will fail in this case as we still set some flags like a Z80 when in 8080 mode.
For me, the past is not over yet. | | Back to Top | | |

| Posted 9/17/2009 4:02 AM (GMT -8) | | heater : I understand your situation with resources. I would like a copy of a bash script though. I am looking to move back to a Linux based environment from the PC. Step-by-step instructions would be helpful to many.
Cluso99: I know the process itself is very simple. The details do get confusing at times. I have always managed to work my way through getting the right files on the SD card. The issue has been with the exact file names on the SD card versus the filenames in the zip archive throughout the history of the project. These have been in a state of flux. Also exactly which files need to go on the SD card and in what order. Having said this the most important reason for me is that I find scripts much easier to deal with over time than having to repetitively do things like copy & paste in a gui.
I (we) appreciate all your efforts on this project. I am sharing this project and its ongoing development with a number of junior high and high school children in our robotics group. They are eager to learn and enjoy learning about the "old days" meaning pre Windows XP for most. CPM and what can be accomplished with this "little board" (TriBladeProp) and the Propeller in general has very much caught their interest. I am sure you would agree.
Thanks

| Posted 9/17/2009 6:01 AM (GMT -8) | | TrapperBob - do you have a triblade soldered up and ready to go? And do you have a micro sd card with some sort of reader device? If so, you are only a few minutes away from getting it working. First step is to reformat the sd card on your reader device with a right click on the drive then "reformat" with fat16. Then copy the .dsk files onto the sd card. Have you got that far?
To Cluso/Heater - something is seriously wrong with this version. It can't run a number of programs that work fine on the Aug30 version.
I have been running off just drive A, and downloading programs via xmodem so they cleanly go onto the drive. Also tried copying to a sd card image and moving that over. Same error either way. Wordstar seems to restart about 10x before it gets to the prompt.
Wordstar package attached.
I tried mbasic reading and writing a file to disk and that works. As do simple mbasic programs.
I wonder if it is the autoexec thing? I remember with the N8VEM it took me about a week to get the autoexec working. It was extremely complicated, yet seemed a simple thing to do. The errors were similar - endless restarts under certain circumstances. I'm trying to find where the autoexec bit is so I can try temporarily disabling it. Not in spin. It is coming up though in the ZIPM2_64.DSK image. How was this built, and is it possible to get a version without any autoexec?
