Problem with flashing the FRDM-KL25Z with new program
Hello,
Today I get a new FRDM-KL25Z but something seems not right with the board: After connection to the PC I could not find MBED.HTM but the following files present there:
cshulev@mmsol:/media/FRDM-KL25Z$ ll
total 116
drwx-- 2 cshulev mmsol 16384 1970-01-01 02:00 ./
drwxr-xr-x 3 cshulev mmsol 4096 2014-03-17 13:03 ../
-r-xr-xr-x 1 cshulev mmsol 512 2012-08-08 22:58 FSL_WEB.HTM*
-r-xr-xr-x 1 cshulev mmsol 68 2012-08-08 22:58 LASTSTAT.TXT*
-r-xr-xr-x 1 cshulev mmsol 1536 2012-08-08 22:58 SDA_INFO.HTM*
-r-xr-xr-x 1 cshulev mmsol 7091 2012-08-08 22:58 SERCDC89.CAT*
-r-xr-xr-x 1 cshulev mmsol 3003 2012-08-08 22:58 SERCDC89.INF*
-r-xr-xr-x 1 cshulev mmsol 512 2012-08-08 22:58 TOOLS.HTM*
Then I compile a simple example for LED blinking and coping the bin file on the board. The file appears in the file browser but after pushing reset button nothing happens. After power reset (unplug and plug cable) the bin file does not present in the board. Could someone help me to start working with the FRDM-KL25Z board?
Regards CShulev

The easiest way to flash the KL25Z with mbed firware is to do it on a Windows machine. I was able to do this on both Windows 7 running on Virtualbox and KVM.

That is correct, see: http://mbed.org/handbook/Firmware-FRDM-KL25Z for updating the firmware

Hi Erik,
Thank you for the quick response. I tried this tutorial for firmware updating but I also have a problem with it. While holding down the small button between the USB connectors, plug the Freedom board into the connector marked SDA. When the FRDM-KL25Z is plugged in this way the BOOTLOADER disk does not appear.

Did you notice the yellow warning message on that page? Either you need to update the bootloader first (which might require also a windows PC, not 100% sure though), or you need to do it on a windows PC. This is a one time thing: After you set it up to use the mbed firmware it will work on a Linux PC, and you won't need a windows PC in the future to for example program your device.
