Gotek with the HxC on an HP1652B

[siredward]

Ok that is in work!

What particular action do you want me to do (to verify your theory). Do I need to put the Logic Analyzer trace up again?

[siredward]

I completed the update to the new version. I don't see any difference from my perspective. Attached is the Logic Analyzer plot and the settings I used, just in case they are useful. Compression produced some moire effects.

Ok, i will fix the firmware for the QFN32 gotek !

[Jeff]

So i have updated the instructions and the firmware for the AT2 QFN32 Goteks :

https://hxc2001.com/download/floppy_dri ... P_1652B.7z

Regenerate the firmware with these settings :

Go to this page :
https://hxc2001.com/custom_fw/

Set :
- "Non gated mode"
- "Floppy Interface mode" to "Advanced pins configuration"
- "Advanced pin 2 configuration" to "nDiskChanged (mode 1 : DSKCHG Clear -> Step only)"
- "Advanced pin 34 configuration" to "nReady"
- Enable Reset DC (Diskchange) input signal (pin PA14)
- Bitrate override : "500kbit/s"

Then go down to "Build order" to generate the new firmware.
Once upd file received by email, you can update your gotek with this firmware.
Update procedure :
https://hxc2001.com/docs/gotek-floppy-e ... pdate.html

Amazing! it all works! After a few months of struggle, you have helped me achieve this amazing feat. The LA boots up correctly (no more System disk error), and I can change disk images. One slight user note is that once I press the Gotek button to change disk image, the 7-segment display will blink about two seconds after button push. I need to wait that long before trying the disk directory.

Now I have one more request/question. I actually have both the original floppy and the Gotek wired on a special ribbon cable to the LA. My intent was to be able to read my old floppies and then copy over configuration/setup files to my new USB system. I was partially successful. I was disabling the floppy by powering down 5V and 12V on the floppy, and I disconnect pin 10 (Drive Select 0) to disable the Gotek. This used to work to the extent that I was able to boot off the floppy, and then partially format the USB drive (all this with the factory Gotek firmware). With your firmware, I am able to boot up with the Gotek without the M0, S1 S0 jumpers. So your firmware appears to not use these signals. Can you modify your firmware to be enabled by one of these signals?

Edit: I have an old laptop with a floppy drive that works, but it won't read HP disks. Neither LIF2DOS nor LIFUTIL works. So the only way for me to read HP disks is with the Logic Analyzer.

Yes this is what the "Non gated mode" do : the bus is always enabled. this is avoid potential issues related to the gotek software latencies since the gotek floppy bus gating is done by software...

So try these settings :

- "Floppy Interface mode" to "Advanced pins configuration"
- "Advanced pin 2 configuration" to "nDiskChanged (mode 1 : DSKCHG Clear -> Step only)"
- "Advanced pin 34 configuration" to "nReady"
- Enable Reset DC (Diskchange) input signal (pin PA14)
- Bitrate override : "500kbit/s"

And set the jumper at the S0 position and retry. if all is working properly you can try to add your floppy drive and redirect the selection signal (wire 10) to select the gotek or the floppy drive.

[siredward]

ok I repeated the build except did NOT check Non-Gated Mode.

The result was a bit odd. It boots up completely, but in the Disk Menu it shows "Unsupported Disk" (even after it just booted correctly from it). Also when I press the Gotek buttons to change disk number, the DCHGE line does not go low. So the LA does not know I changed the disk. It looks like these options don't work for me. All this with the M0 jumper in (pin 16, MOTOR ON). Using jumpers S1 (pin 12, DRIVE SELECT 1) or S0 (pin 10, DRIVE SELECT 0) does not work at all. It does not find the disk.

BTW of the above, only MOTOR ON toggles. DRIVE SELECT 1 and DRIVE SELECT 0 are static. DS0 is low all the time.

[siredward]

After thinking about it some more, it dawned on me that I don't want dynamic control of the enable/disable, but a manual one. So as a test, I jumpered pin 14 of the jumper block (goes to FPI5V_DSELn) to ground and the Gotek operated normally (always enabled this way). Removing the jumper and allowing PU4 to take the control line high allowed me to boot off the floppy (Gotek always disabled).

So now I need to modify my interface harness to be able to switch between one or the other. Doing so would be to the Logic Analyzer like I popped the floppy out and put a new one in. I will update once I do that.

[siredward]

With some temporary mods to my harness I was able to toggle between the floppy and the Gotek . I will tidy up my harness tomorrow and put in a switch to easily go between the two modes. I will certainly document all this on my blog and post a link to it.

So finally all is working as it should ?

Yes Jeff, thanks to you it all works. Here is my blog (still being edited):

I know you suspended the fee this Summer for the HxC package but I would like to buy you a coffee. I can Paypal you, let me know how. Thank you again, sir!
