Hi

downloaded the openwrt-15.05.1-brcm2708-bcm2709-sdcard-vfat-ext4 file and wrote to formatted sd card as per instructions

nothing happens on the serial and it does not seem to boot if i look at the green led


i verified the setup with the jessie light image and that works perfectly


any pointers are welcome

EDIT: by serial i mean i have a 3.3v ftdi cable connected to my pc... and as said it works fine with the jessie light image

Are you sure you wrote the image file to the card following the right instructions? The "formatted sd card" part of your message tells me perhaps you didn't...

yes i did

i just formatted the card first to make sure there was no old stuff on it

then i used win32diskimager to write the image to the sd card

the instructions i used are these ones:

How to flash OpenWrt to an SD card

On a Linux desktop, insert your SD card and run:

dmesg
to see the latest kernel messages.

The most recent message should give you the SD card's device name, such as sdb or sdf or similar.

Download the relevant openwrt-brcm2708-bcm2708-sdcard-vfat-ext4.img or openwrt-brcm2708-bcm2709-sdcard-vfat-ext4.img image.

As the root user, use dd to copy the image file to the device you identified previously, for example:

Raspberry Pi

dd if=/home/username/Downloads/openwrt-brcm2708-bcm2708-sdcard-vfat-ext4.img of=/dev/sdX bs=2M conv=fsync
Raspberry Pi 2

dd if=/home/username/Downloads/openwrt-brcm2708-bcm2709-sdcard-vfat-ext4.img of=/dev/sdX bs=2M conv=fsync
Replace the sdX with your device name, such as sdb or sdf.

On a Windows desktop, use Win32DiskImager to copy the img file to your SD card's drive letter.

but since i'm on windows i do

1. format the sdcard with SDFormatter
2. write the image to card with Win32DiskImager

The discussion might have continued from here.
