Title: How to build flashimage
Post by: zgyarmati on November 13, 2016, 12:24:44 pm
 On the olinuxino github site there are pre-built images (https://github.com/OLIMEX/OLINUXINO/tree/master/SOFTWARE/RT5350F/Prebuilt%20images) which can be loaded directly into the flash memory, but i failed to find any instructions how to build these image from the bootloader, factory and openwrt squashfs partitions. Is there any information available on this somewhere?

The wiki and openwrt at least?

E.g. https://www.olimex.com/wiki/RT5350F-OLinuXino
https://wiki.openwrt.org/toh/olimex/rt5350f-olinuxino-evb

 Thanks for both the responses, although it's not exactly what i'm looking for:
I know how to build the u-boot and the openwrt images, but i'm looking for a way to tailor all the partition images together and be able to flash it directly to the SPI NOR flash memory, as described here: https://www.olimex.com/wiki/RT5350F-OLinuXino#Upload_prebuilt_images_using_programmer_tool

I suppose the partition images has to be concatenated together (for example by using dd) with padding where necessary, and i'm in the hope that somebody has set this up already so i don't have to experiment with this (and risk my HW).

I flashed the firmware (no bootloader) : https://www.olimex.com/wiki/File:Arm-usb-ocd.png
with ./flashrom but I had to pad the image to the size of the NOR flash before like so :
dd if=/dev/zero of=image_to_pad.bin seek=(NOR_flash_size_in_bytes - 1) bs=1 count=1
