 +=== Firmware ===
 +
 +Out of the box this board doesn't work with anything resembling a modern
 +day computer so I never used it until 8 years after buying it in 2014.
 +
 +Without an upgrade it doesn't work in any variety of Linux or Windows after 7.
 +The fact that it doesn't work with anything except XP and 7 means it's
 +very hard to upgrade.
 +
 +You have to download new firmware to upgrade the bootloader from version 0.11
 +to something higher that will work with a modern PC. Somehow I managed to get it
 +to upgrade using Windows XP in a VirtualBox VM.
 +
 +Once the upgrade magically worked I further updated it from OpenSDA to J-Link for NXP.
 +
 +The files I think I used to proceed were (I have a bad memory but this is probably close):
 +
 +<code>
 +DEBUG-APP_Pemicro_v108.SDA
 +BOOTUPDATEAPP_Pemicro_v111.SDA
 +12_OpenSDA_FRDM-KL25Z.bin
 +</code>
 +
 +Good luck.
