I am working on FRDM-K8F board. It has open SDA support. It is not entering bootloader mode if if i press the reset button and then power up. So i request you to share with me .s19 or srec file for opensda as I am using PE Micro as debuger.
The OpenSDA can been download from here: OpenSDA Serial and Debug Adapter|NXP
However I highly recommend you may have a look at this post, especially when you can not see the "BOOTLOADER"
