| tpb | <robin7g> I will try this on a Linux machine with a fresh install of the tools. | 00:00 |
|---|---|---|
| tpb | <robin7g> (I am using macos currently and it worked fine last week on this machine with another fomu) | 00:01 |
| tpb | <robin7g> I am expecting the blue flashing when I plug it in but nothing | 00:01 |
| tpb | <robin7g> If I plug it into a Linux box running Ubuntu this is the error message. | 00:03 |
| tpb | <robin7g> sb 3-4: new full-speed USB device number 10 using xhci_hcd | 00:04 |
| tpb | <robin7g> usb 3-4: Device not responding to setup address. | 00:04 |
| tpb | <robin7g> usb 3-4: Device not responding to setup address. | 00:04 |
| tpb | <robin7g> usb 3-4: device not accepting address 10, error -71 | 00:04 |
| tnt | Yeah. either there is a bad contact or the bootloader has been erased. | 00:04 |
| tpb | <robin7g> usb usb3-port4: unable to enumerate USB device | 00:04 |
| tpb | <robin7g> How do I reinstall the boot loader? | 00:05 |
| tnt | There are tiny test points giving access to the spi bus of the flash. Then you need a flash programmer. | 00:06 |
| tpb | <robin7g> I think the USB contacts are fine as I can see scoring on the pad from inserting and removing it. | 00:07 |
| tpb | <robin7g> is there a link to the flashing process something. I can create an SPI bus programmer I think. | 00:07 |
| tnt | there is a sw to use a rpi as spi programmer : https://github.com/im-tomu/fomu-flash | 00:09 |
| tnt | https://github.com/im-tomu/fomu-hardware/blob/master/archive/pvt/images/fomu_pvt_test_points.jpg | 00:09 |
| tpb | <robin7g> Okay so its just a matter of connecting the tiny test pads.. that looks hard. but I don't think AdaFruit will accept a return after all this time and they are out of stock anyway. | 00:11 |
| tpb | <robin7g> Luckily I have a raspberry pi from before the supply shortage. | 00:12 |
| tpb | <robin7g> Thanks for your help. | 00:12 |

| tpb | <robin7g> these are really small pads but I think I can see the original test pin marks. I wonder what happened. | 00:27 |
