Does not work on my C-64

[C-64Bram]

hi! Build myself the Kung Fu Flash. Great cartridge!!

As described in Github I booted the device in DFU mode. Renamed the firmware from upd to bin and used DFU file manager to create a dfu file. Flashed the file with DefuSe and verified. No errors. So far everything ok. Removed the 2 jumpers and went to my C-64. When I put the cartridge in the C-64, the screen stays black and the cart won"t start. I've tried different firmwares but no result.

Could be a NTSC C64? did you check 100R array resistors?

[C-64Bram]

It's pal. Checked the array resistors and they are in place.

[jgilcas]

Could you try to use dfu-utils? there is a win64 version available, working fine with following command dfu-util -a 0 -s 0x08000000 -D KungFuFlash_v1.10.upd

[C-64Bram]

Is there a 32 bit version? I have 32 bit windows :-)

Thanks! Will try it later. Have to go to work now.... :-(

Tried with DFU-Utils. Did not work. :-( I quess because of the suffix because what the error sais... :-))

Invalid DFU suffix signature A valid DFU suffix will be required in a future dfu-util release!!! Cannot open DFU device 0483:df11 No DFU capable USB device available**

So I used DFU file manager to create a DFU file from the BIN -file. Strangely the created DFU file is only 336 bytes. So something is going wrong.......

Hello, with the dfu-utils I used the .upd binary what I have downloaded from here (github), without any conversation (I used linux under VirtualBox under win10).

[C-64Bram]

hi. if I load the .upd-file with DFU-utils it says "this file does not have the correct format".

[dikdom]

Hello, this is I received last time I flashed a KFF device:

~/devel$ dfu-util -a 0 -s 0x08000000 -D KungFuFlash_v1.09.upd

Just had a thought. I have had this issue with the resistor ladders not being soldered in correct. Once run over with an iron and some flux and no more black screen. Just a thought

[C-64Bram]

Hi. Thanks! I am going to retry building it in a few days and also reworking the non-working ones.

Best regards, Bram.

Just my 2 cents: if you get the error "No DFU capable USB device available" from dfu-utils on Windows, you probably need to install the USB driver for the ST DFU mode. The regular ST tools driver conflicts (is closed source) with what dfu-utils need. You'll need to follow the steps for example here. Short version:

• Plug in the STM32 usb in your pc, making sure its in DFU mode
• Install Zadig

I just had the same issue. I checked all connections on the 2 resistor networks and there was one loose solder joint. Thanks to this thread I found it right away 👍

Hello brother, I want to know how much thickness should be selected when making pcb

I'm using 1.6mm enig with golden fingers.

thanks,bro,Does the thickness have no effect on reading?
