Discussion - MCU / Re: One-wire programming method for FT9xx documented?
« on: October 24, 2019, 06:27:30 PM »
Thank you, that sounds good.  3-pin connector is not so bad to add.  Might use Servo cable...

Ok, I think I've determined that my issue was due to launching the Programming Utility from within Eclipse.
On 3 out of 4 computers that I've tested, this and other things do not work properly.
But, when the Programming Utility is launched from Windows Explorer, it works.

Discussion - MCU / Re: Can one program D2xx example using DFU?
« on: October 24, 2019, 06:04:23 PM »
Thank you.  I just tried this again and it worked!

I'm going to test on one of the other computers I was working on to see if it's something with the computer.
I also have this issue of the programmer utility not working when launched from Eclipse and it may be something to do with that...

Anyway, I'm glad that DFU programming with D2XX is possible!

This is all with D2XX firmware...

I do have somewhat better luck on a forth computer.  On this one, it only sometimes loses connection either inside Eclipse or from the .bat file after selecting the programmer and hitting the "Next" button on the FT9xx Programming Utility one-wire interface dialog.

At this point, it sometimes works and populates the D2XX tab, but more often it says "There is no response from the MCU.  Please check the connections (power, data) and try again.  Now, I can hit the "Scan for device" button and it will sometimes populate the D2XX tab.

But, sometimes it freezes and Eclipse freezes too.  At this point, you need to CTRL-ALT-DEL and end the task Eclipse task to recover...

I think I'm going to never use the programming utility from inside of Eclipse.
Instead, I'll use it with this:  FT900Prog GUI Launcher.bat
located here:   C:\Program Files (x86)\Bridgetek\FT9xx Toolchain\Toolchain\programmer\dist

I don't know how or why, but the one inside Eclipse does not work or does not work as well, at least on the four Win10 PCs I've tried it on...

Ok, thanks.  That's what I figured...  I saw "Proprietary" somewhere about this...

Can I use just a 2 or 3 pin header from the programmer board to the board with the FT93x chip on it?

Do I just need the DBG and GND signals to program?  Or, do I need reset# too?

Actually, I think I just confirmed this behavior on a different computer.
Programming utility barely working from inside Eclipse, but works fine with the directly link posted above.

Just tested on a third computer, same thing.
Funny, you can program via 1-wire just fine inside eclipse, but the utility doesn't work when invoked from Eclipse.
I suppose that is because the programming is done with FT900Prog.exe and not the GUI utility.

I'm really surprised nobody else had this difficulty...

I was playing around with this and it started working.  Not sure why.
One thing I did when it worked was launch the utility using:
FT900Prog GUI Launcher.bat
located here:
C:\Program Files (x86)\Bridgetek\FT9xx Toolchain\Toolchain\programmer\dist

I can't imaging that was the reason why it started working though...

Thank you.  I did figure out today how to program the "GPIO DFU" example using the DFU interface.

I changed this line in the example so I didn't have to mess with I/O pins or UART pins:
volatile int trigger = 1;//RJA Force DFU on startup 0;

However, I'm still not able to program the D2XX example over the DFU interface.
Still getting the error message described in top post.
Is it possible that D2XX code cannot be programmed over DFU?

Discussion - MCU / How to get D2XX tab on programming utility to work?
« on: October 22, 2019, 02:59:52 PM »
I don't seem to be able to get the D2XX tab on the programming utility to populate...
I've tried three different computers and three different FT9xx boards with same result.

I can see the USB device that this needs until I hit the scan button and then it disconnects...
What am I doing wrong?

Discussion - MCU / One-wire programming method for FT9xx documented?

It would be convenient to be able to reprogram the FT9xx using a microcontroller that will be on the same board.
But, to do this, would need details on the 1-wire programming method.
Is this documented somewhere?

Discussion - MCU / Can one program D2xx example using DFU? Answer: YES
« on: October 16, 2019, 11:27:27 PM »
I'm just starting with FT93x...

Trying to program the "D2XX Example UART Bridge" example over USB using DFU...

I think I followed the directions in the video, but I get this error message:
"The binary file contains D2XX section.  DFU only allows firmware update.  The binary file is incompatible".

Does this mean that any program using D2XX cannot be programmed over DFU?
