“/etc/dnsmasq.d/dnsmasq.wlan.conf: No such file or directory”

Not sure if this line makes problem.

You can have a look on this thread, there is cfg_gateway.sh to set up the dns server for ethernet interface:

Hi jyijyi,

the above link i dont get any info on how to enable the dchp on MangoH red board.

Is there any dhcp command as such which can be run when the board comes up ?

I saw there is such thing in the link:

Generating the configuration file ‘/tmp/dnsmasq.eth0.conf’ for the DHCP server…
Restarting the DHCP server…
starting DNS forwarder and DHCP server: dnsmasq… done.
MangOH gateway configuration completed

Ok here is something that i guess would have caused this problem.
I had flashed yocto seperately. Does this have some issue when the firmware is updated.

currently i m trying to update to release 12, but my board is not going to download mode.
I want to erase everything adn reflash again. Any steps in particular to be followed ?

You need to use swiflash tool on r12

7

yes i am using the same swiflash tool on ubuntu, but MangoH red board does not go to download mode at all.
Any dip switch setting ? On mine 3 and 8 are high on SW401

How about entering “at!boothold”

thanks jyijyi!! was able to flash and get dhcp up and running on the Board.
Mentioning the steps below so that it might help someone facing the same.

Steps followed.
a. On the WP AT cmd terminal entered - “at!boothold” - MangoH red board enters into dnld mode. Due to some reason the board was not going to dnld mode from the swiflash tool.

b. Using the swiflash tool, flash R12 image from PC. This image has support to erase rootfs and kernel image.

swiflash -m "wp76xx" -i WP76xx_release12_Generic_GCF.spk

c. Reboot the board.

d. Using swiflash too, erase the rootfs and kernel

 swiflash -m "wp76xx" -r

e. Flash the R13 / R12 image, using the command as in step b. Reboot.

f. After reboot, on wp76xx, assign ecm0 192.168.2.2 and on the PC the usb0 is assigned with 192.168.2.3 automatically.
g. On the MangoH red board, check for dhcp in dmesg.

How about using windows exe file to update?

Try “AT!BOOTHOLD”, this will put board into download mode and then try the swiflash commadn.
