What is the difference between the generic mbed bootloader and the bootloader on the freedom board? I used appendix b of the DOC-100720 to put the bootloader on a K22 freedom board. It went on and started up just fine. Then I MSD'd the 0221_k20dx128_k22f_0x8000.bin file on after which the status light blinked fast which I assume was indicating an error. It did not start after that for an normal power on boot. I've done that on both a freedom board and my own pcb. Any ideas. Thanks.
