ReSpeaker Core v1.0 – uboot load and run addresses for respeaker linux image

Hello,

I have been really stupid and replaced the Respeaker linux image with a stock OpenWrt Image, which provides no networking support on the Respeaker Core v1.0 .

However uboot is untouched and does support a load via serial function. Unfortunately I am not sure that the default load address is correct. So I am really hoping someone might be able to tell me the correct:

  • Load address for the ramips-openwrt-latest-LinkIt7688-squashfs-sysupgrade.bin image
  • Execution address for the “go” command

It is quite possible that a serial terminal connected when a linux is rebooted “reboot” would show this.

I have also looked at the possibility of a USB boot, but the github page [https://github.com/respeaker/get_started_with_respeaker/wiki/Rescue-from-a-failed-upgrade] is very unclear on the connections for a USB device showing only a photograph for this. I am tempted to try using the reported USB pins USBDP and USBDM, but this might be contrary to the instructions.

Any assistance so I can actually get to play with the Respeaker Core v1.0 would be greatly appreciated! :slight_smile:

I have actually overcome this now by booting from a USB stick, using the USBDP and USBDM labelled pins. Uboot option 5 actually writes the loaded image to flash after loading it, making this a nice recovery path
Now just need to get the 192.168.100.1 device (interface) working.
