Ubuntu updating bootloader
The latest firmware version for the FRDM-KL25Z is: 0243. While holding down the small button between the USB connectors, plug the Freedom board into the connector marked SDA - the bottom one as shown. These instructions explain how to upgrade your firmware.
Later boards (as FRDM-K22F) are using Open SDA V2.1 where the application starts at address 0x8000.As the P&E debug connection knows .elf/and S19 files, I have to convert the binary (.bin) into an S19 file first, then specify it in the debug connection, using the K20DX128M5 as a device. The MBR is the very first code launched in the boot process by the BIOS.You’ll need to reinstall their boot-time helpers after configuring Easy BCD.The new Windows bootmgr/bcd bootloader is installed to your first-boot hard drive’s MBR the first time you install a “BCD OS” – Windows 8, Windows 7, Windows Vista, and Windows Server 2008 – and every time thereafter it is updated or rewritten depending on its status.
