Netgear XR500 support?

For Developers

@jordanp: exactly same behavior! + serial console is responding at all. In my case there were few times firmware changes official -> openwrt -> official. Then on official firmware "it was working fine", suddenly it stuck in this mode after reboot one day, for now didn't find way to bing it back (I have idea to do it using JTAG, however I cannot find any documentation how to put SoC in mode that allows me load uboot to ram then boot it from ram (same as it's in Mediatec SoC). the switch mode might be "default" one when uboot cannot be loaded (due to broken ext memory or broken uboot).

I have crazy idea... since usb2 led is lighting, and uboot is broken - it may be something similar as in Phone with QCA SoCs (I have hope that engineers were lazy and same tick can be reused here) - In next weeks I will check if SoC is in EDL mode so firmware might be pushed trough usb using firehose programming...

Can someone make bootlog including uboot for me?

OpenWrt does not use nvram, but uci show will provide a rough equivalent (with a very different syntax and semantics) - respectively fw_printenv from the uboot-envtools package to display the bootloader configuration.

45

Any help on how would i overclock my cpu using the uci, or how to check what freq its running at i know when i ran the ddwrt firmware the cpu ran at 800hz on this router for some reason untill i ssh nvram set clkfreq=1725,800 would like to do the same for open wrt as im not getting my full throughput .

I have the exact same thing happen to my XR500... only USB2 light on, and neither TFTP or Serial connection will work. Did you ever find a solution?

Thanks!

47

Not sure what it actually means, but I can help you if you guide me. Are you still interested? Have you found a way to recover your XR500 in the meanwhile?

48

I have the same problem: uboot probably erased. Now only USB2 light on and no output from serial.
Did anyone find a way to boot this SoC from RAM using JTAG port?

Hi everyone!

Sorry to dig this old thread but, has anyone been able to fix this router in this state (USB2 light on, no TFTP or Serial connection and in a 5-port switch)?

Thank you!
