I download openwrt 15.05 branch (Chaos Calmer) using

git clone -b chaos_calmer git://

run make menuconfig to configure it to target system "Freescale i.mx23/i.mx28" and target profile "Olimex Olinuxino maxi/mini boards"

run make V=s

and I obtain in the following dir ...bin/ mxs the next file


and using windows win32diskimager I copy to SD card

I load my custom board but my output is

U-Boot 2015.01 (May 03 2017 - 20:41:15)
CPU:   Freescale i.MX23 rev1.4 at 454 MHz
DRAM:  64 MiB
*** Warning - bad CRCCOMMA using default environment
In:    serial
Out:   serial
Err:   serial
Net:   Net Initialization Skipped
No ethernet found.
Hit any key to stop autoboot:  3 '8''8''8' 0   ('8' es un backspace)

I not have keyboard to write something

I see in the next comment

Further notes

The board uses a special boot image called bootstream / safeboot. The file includes a zImage, a compiled devicetree, and various preparation bootlets (power_, sdram_, linux_)- these are contained in package/imx-bootlets. The image is created by the elftosb tool.

My question is

How can i copy the correct files to SD card and with what tool

Thanks for your help

Since your system is successfully starting u-boot, your SD card seems to fine, actually.

You do not need a key board: The same serial connection, that provides the output, that you are showing, also can be used for input...
