I have just assembled a custom board using MKL43Z, with a brand new chip.
When I connect it to the USB, it is enumerated as Kinetis bootloader.
However, when I run blhost get-property 17, it returns that the device is SECURED....
Is that correct for a brand new Chip?? What can I do to program it and/or remove the security??
I have tried to unsecure it via blhost with no success:
Is the new Chip lost?

Is there any way that does not involve a third party hardware?
I don't have a segger J-link and to buy one would not be ideal for mi right now, is there any other way?
I just happen to have an Olimex-arm-usb-ocd-h + arm-jtag-swd + arm-jtag-20-10, is it possible to use that setup to unsecure the chip??
