How to get/program OpenSDAv2.1 bootloader?

Hi,

I am working on a project that involves a Freescale/NXP MK02FN64VFM10 microcontroller. To download my code to this device, I use a FRDM-K22F development board. This was working, until, somehow, it didn't...

The MK20DX128VFM5 OpenSDA device on the development didn't show up in Explorer anymoren, not even as bootloader when holding the reset button while plugging in.

I used another development board to download the OpenSDAv2 bootloader to the MK20DX128VFM5 of the original development board. This worked well, now it shows up as bootloader again. However, to drag and drop the MBED firmware does not work (I was able to do this before). When I inspect the Bootloader drive, I see a bootload.htm file, and not mbed.htm. This means that the bootloader I programmed is OpenSDAv2.0, and not OpenSDAv2.1 (according to https://community.nxp.com/docs/DOC-100720, under 'OpenSDAv2 Bootloader'.

So my question is: where/how can I get the OpenSDAv2.1 bootloader? The v2.0 bootloader I am currently using, I also got at https://community.nxp.com/docs/DOC-100720, at the bottom of the page, .

Thank you in advance, Maarten
