This firmware is quite old... Anyway about the Gotek- HxC all is there (files + updates) : https://hxc2001.com/download/floppy_drive_emulator/HXCFEUSB_HFE_beta_firmware.zip https://hxc2001.com/download/floppy_drive_emulator/index.html#stm32hxc https://hxc2001.com/store/ @jedimatt42 : Conversion to HFE is not needed anymore with the hxc firmware.

With the HxC firmware you can use both in read & write mode.

I have fixed the KF Stream loader. this one was broken since a month. The dump is fine : But the bitrate is not quite 250000. 7.6us instead of 8us. And the lower part at 4us show something that look like an write compensation effect. unless the flux reversals on the disk are migrating...

And this is the same software used by arcadeshopper ?

Well in this case still only 2 solutions to understand the problem : - Raw Kryoflux stream files. or - an oscilloscope on the Write Data & Write Gate lines...

no, what i ask is : have you already tried to write files with this controller and the "lotharek" emulator on HD images ?

According to the documentation it seems possible to change the write precompensation, at least for the hard disk. not sure for the floppy...

Here are the HDC9234 write pre-compensation possibilities : If it is set at 600ns or 500ns during HD formating the flux capture will probably fail... I can tweak the capture routines to make it work but i don't have this FDC here to test the modifications. BTW is normal writing working fine on HD disk with this controller ?

Thanks. i don't see the schematic in this pdf. I see 2 possibilities : - The FDC write-precompensation setting is quite aggressive which make the pulses capture not working properly. Is there a way to change this parameter ? Or - The emulator is forced at 250kb/s (can be forced in the internal menu...)

Thanks. Everything look fine. So unless there is no flux coming from the FDC the image should be at least altered... You are formatting in HD mode ? EDIT : It is altered and it is similar to the BeeryMiller image. Is there a schematic of the HFDC available somewhere ?

Then this is becoming odder : The image is not altered at all. Look like nothing was written to the image. Did you saw "WA" on the lcd during the formatting ?

The image look fine. i suppose that this is not the one coming from your sdcard/usb stick after the failure ?

Yes me too. No HD images in the link pointed by acadiel.

Please share the failed HFE file.

they look fine but please note that there is no HD images in this images.

If this is for the HFDC emulation, it is maybe more interesting to format a true floppy disk and redump it with a kryoflux/scp board, isn't it ?

I don't know, i know nothing about these controllers, but anyway take your HFE file and open it into the hxc software. you will see that the track viewer that there is no sector at all. i suspect that the bitrate used by FDC is for 360 RPM drives, at 300kbits/s instead of 250kbits/s. You can anyway change/force the bitrate with the internal menu.

Regarding what i can see in this HFE, i think that there is a bitrate mixup. Please be aware that you can't change track density into the HFE : An DD HFE can't be changed to HD, a HD HFE can't be changed to DD or SD, etc. The track size is different at each density. Do you know which bitrate is used with this controller ?

Just copy ST files to the stick. select "000" and reset the computer to load the manager to assign the images in slots.

You can format an image on the HxC drive, at least since the Rev B hardware version.

WIZARDSDOOM.DSK and ZOMBIv45.dsk are DD images, so since your controller doesn't support DD format, the error message is normal. About Freddy.dsk : Have you tried to convert it in HFE to see if you have the same error ?

First point : The boot sectors of these images are totally blank ! So the disk type is only based on the file size... The right disk format can't be detected in the DSSD80 case... Please consider these images as broken... You need to "format" them in TiimageTool to get the proper boot block.

To avoid any confusion : SD HxC != Gotek HxC. The firmware i have released here is for the Gotek HxC !

So this is perfect since this is the main subject of this thread and i have done the update for the HxC Gotek 3 weeks ago.

No. For me : No feedback just mean that no nobody have tested it. After 2/3 weeks i got here only one feedback with very few dsk tested... It seems that very few users are interested by this feature. Why you don't test the new HxC firmware since you have asked me this support since some months ?
