Using Linux to upgrade the FW for KL25Z

Hello, How to upgrade FW using a Linux host. Does the instructions at (https://mbed.org/questions/3702/Using-Linux-to-upgrade-the-FW/#answer4271) for KL46Z hold good? Thanks, -Gitesh

Question relating to:

if original bootloader is older than version 1.11 in order to update it on linux you have to unmount the auto-mounted BOOTLOADER volume after taking note of the corresponding device (that should be some kind of usb disk like e.g. /dev/sdc or /dev/sdb or whatever), then mount it to a temporary mountpoint using msdos, e.g. mount -t msdos /dev/sdc mytempmountpoint. after that you should be able to copy the new bootloader file to the mounted disk, unplug, replug and you're ready to upload MBED fw

That depends on the version of the bootloader installed on your FRDM board. In any case, using a Windows 7 PC or older will work. To see the version hold the reset button down, connect the USB to openSDA and then open a file called SDA_INFO.

Thanks, I plan to use a windows machine for first upgrade and then on I believe dragging and dropping on Linux m/c should work for application programming.

BTW, right now I am not able to see SDA_INFO file as website seems to be down. Is their a other way to see the version of bootloader?

I am able to flash the latest bootloader using Windows XP. After that KL-25Z is getting flashed using Linux. Thanks Sam.
