Another odd Omega not booting problem

@Harvey-Golob That's so strange... Can you give us the output of help?

Also, are you using Windows or Mac or Linux? We will need you to host a tftp server on your computer. Let me know if you know how to do that. If not we can show you how to do it.

Running Win 7. Have setup TFTP Turbo4 and was going to attempt tftpboot of the latest firmware but can't seem to get the ethernet link working in uboot. Maybe I'm missing something?

Boken Lin

@Harvey-Golob Can you try the following?

setenv ipaddr 192.168.1.1   
setenv serverip 192.168.1.100
tftp 0x80000000 uboot.bin
erase 0x9f000000 +0x10000
cp.b 0x80000000 0x9f000000 0x10000

The uboot binary can be downloaded here: https://s3-us-west-2.amazonaws.com/onion-downloads/openwrt/uboot_for_omega_final.bin.

@Boken-Lin I'm doing this over my LAN so tftp server is at 192.168.0.102. When running tftp get this:

ar7240> setenv ipaddr 192.168.0.200
ar7240> setenv serverip 192.168.0.102
ar7240> tftp 0x800000000 uboot.bin

When setting IP on the Omega in Uboot have not been able to ping from either end, yet when Omega boots to Linux can ping from both sides of the connection...

Boken Lin

@Harvey-Golob When you say you are doing it over LAN do you mean you are connecting the Omega to your router and trying to flash the Omega from your computer, which is also connected to your router?

Harvey Golob

@Boken-Lin Yes.

Boken Lin

@Harvey-Golob Is there anyway you can try Omega to computer direct? Uboot is a very small program, so it doesn't have the dhcp stack built in. Your router typically assigns IP via DHCP. Even though with the setenv command you are setting the static ip of the Omega to 192.168.0.200, it might not be recognized by the router (because the Omega in uboot isn't responding to the router with dhcp protocol).

Harvey Golob

@Boken-Lin I was wondering if something like that might be the case. Will setup a laptop with the Tftp server and try...

Boken Lin

@Harvey-Golob Ok. Keep me posted.

Harvey Golob

@Boken-Lin It's ALIVE....., thanks for the help, I had moved the connection to the laptop yesterday but didn't try tftp on the laptop.
Reflashed Uboot and httpd to load the latest Omega firmware an its up and running. Now to tackle wifisetup

Sawyer McBride

Was going to say make sure your host firewall is turned off on windows as that is generally the biggest problem when hosting stuff on a windows desktop! (Windows firewall normally, obviously turn it back on after, alternitively create a rule to allow ping and tftp through)

Harvey Golob

@Boken-Lin Omega seems to run as expected except no wifi, have gone over another post related to no wifi and can't get any response from Omega as far as wifi set up. The following is what I get.

The last post to https://community.onion.io/topic/135/omega-can-t-connect-to-wifi didn't seem to have resolved similar issues. Any other suggestions?

Boken Lin

@Harvey-Golob If you run a hotspot on your phone, are you able to detect it via the wifisetup command?

Boken Lin

@Harvey-Golob I think I figured out the issue. You also need to flash the ART partition on the Omega. Can you start up httpd from your uboot again, and at the bottom, there should be a link to flash ART. the ART partition binary can be found here: https://s3-us-west-2.amazonaws.com/onion-downloads/openwrt/art_for_omega.bin.

Harvey Golob

@Boken-Lin Flashed ART just now, no change. Also tried hotspot suggestion, scan from Omega still fails. ifconfig only shows lo and eth0. Headed to work now, will check back end of day.

Boken Lin

@Harvey-Golob You will need to do a factory reset after flashing the ART partition. On first boot, the Omega will read from the ART partition and setup its WiFi.

Sorry about the confusion!

Harvey Golob

@Boken-Lin Finally got back to this, started Omega, did factory reset and still no wifi. Just to be sure dropped to Uboot and started httpd and tried to reflash ART. Then did factory reset and no change.

Boken Lin

@Harvey-Golob Can you try reflash both ART and the rootfs partition from uboot?

Harvey Golob

@Boken-Lin Reflashed firmware (omega-v0.0.5-b238) and let boot, then restarted and reflashed ART, let it boot and then factory reset, still no change. Missing something?
