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?

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
