| xobs | Unfortunately, an unconfigured FPGA places weak pullups on all pins, meaning an unconfigured FPGA will attempt to enumerate over USB. It could be that it's not able to configure itself. | 02:53 |

| tnt | Is the 'done' pad exposed ? | 09:21 |
| tnt | might be worth probing. | 09:21 |
| xobs | It is exposed, yeah. Good thinking. | 09:23 |

| tcal | Hi all; are there any tricks to getting iceprog to work with fomu? I updated udev rules according to the Fomu workshop. This is the info I get from dmesg: | 22:49 |
| tcal | [510716.745828] usb 1-4.4: new full-speed USB device number 57 using xhci_hcd [510722.021701] usb 1-4.4: New USB device found, idVendor=1209, idProduct=5bf0, bcdDevice= 1.01 [510722.021707] usb 1-4.4: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [510722.021750] usb 1-4.4: Product: Fomu PVT running DFU Bootloader v2.0.3 [510722.021753] usb 1-4.4: Manufacturer: Foosn | 22:49 |

| tcal | Sorry about that -- mainly, `New USB device found, idVendor=1209, idProduct=5bf0, bcdDevice= 1.01` | 22:50 |
| tcal | So I tried: sudo ./iceprog -v -d i:0x1209:0x5bf0 foboot-bitstream.bin | 22:50 |
| tcal | And I see: | 22:51 |
| tcal | Init.. | 22:51 |
| tcal | Can't find iCE FTDI USB device (device string i:0x1209:0x5bf0). | 22:51 |
| tcal | ABORT. | 22:51 |
