Hi,
I built Stefan's xu1451 project from https://github.com/wagiminator…on/tree/master/C64_xu1541. Based on the instructions, I am able to flash the usbtiny bootloader using an usbtiny programmer. I see the TWO LEDs on, meaning that I have not flashed the firmware. I try to flash the firmware using the command "xu1541_update.exe firmware.hex" on WINDOWS but nothing happens. This is where I am stuck.
When I unplugged the programmer and connect the xu1451 to my computer via a USB cable, I see that WINDOWS shows the below in the device manager window. It looks like the "xu1541" driver is not fully working or recgonized by WINDOWS.
How can I upload the firmware successfully via the xu1541_udate.exe utility? If I try flash the firmware.hex file using my usbtiny programmer, it does so successfully BUT WINDOWS won't recognize the xu1541 board as a USB device. That's because the bootloader is overwritten.
Thanks for any tip!
