FRDM-KV10Z Can't program (Stalling); MBED Volume 32k free space

[eljeffo]

Is this normal?

Filesystem      Size   Used  Avail Capacity   iused     ifree %iused  Mounted on

/dev/disk4      48Ki   16Ki   32Ki    34%        32         0  100%   /Volumes/MBED

I tried to load hello_world.bin from the SDK but I got some errors:

cp: hello_world.bin: could not copy extended attributes to /Volumes/MBED/hello_world.bin: Device not configured

I then tried PyOCD but then I got this:

$ pyocd-flashtool -u
INFO:root:DAP SWD MODE initialised
WARNING:root:KV10Z7 in secure state: will try to unlock via mass erase

When that failed, I tried upgrade OpenSDA but now there's not enough free space to upload anything at all (even in bootloader mode).  The Segger OpenSDA bin files are well over 32k.

Trying to copy a smaller item results in a never finishing copy:

$ cp k20dx128_bootloader_0x8000.bin /Volumes/MBED #stalls "forever"

And now trying to replace the demo app (in non-bootloader)

$ cp ecompass.bin  /Volumes/MBED/ # stalls forever

Perhaps there's something I'm missing?

Did my KV10Z somehow get locked and that's why I can't write a new program?

Is my bootloader working properly?  Is it showing up as the MBED volume proof enough that my bootloader isn't bricked?  If bootloader is okay, why does updating the bootloader (in bootload update mode; reset pin down on power-up) stall on copy?

Tried in windows as well but no luck

So I'm trying with a Segger Jlink.  I cut J8 and J12 to isolate the KV10Z and here's where I am so far.

1) You'll see a reset attempt fail with just the SWD_DIO/CLK attached

2) You'll see that even pulling reset low for the KV10Z does not seem to help the situation

Okay moved the Jumper and reflashed OpenSDA2 onto the KV10Z board.

However... still the same copying problem.  

Is there some chance I got a locked Kinetis from the factory?

How long does this mass-erase to unlock take?

Tried to check if holding down the reset button during boot would give me a BOOTLOADER volume but it doesn't.  I get an MBED labeled volume whether or not the reset button is down.  

Is this correct?  Do I have a broken reset button?

Just to verify it wasn't a mac problem I tried uploading a .bin file via Windows 7.  Same issue, board completely stalls:
