Just got a new TWR-K20D72M and am attempting to debug with it from KDS.

P&E GDB Server, Version 5.07.00.00

Loading library C:\Freescale\KDS_1.1.1\eclipse\plugins\com.pemicro.debug.gdbjtag.pne_1.1.2.201408071632\win32\gdi\unit_ngs_arm_internal.dll ... Done.

Device is secured. Erasing ...

PE-ERROR: Error downloading to the device.

Things I have checked:

* I have checked that the "Always Mass erase on Connect" flag is checked.

* I have checked the jumpers (J16 in particular).

On failing, the tool says it cannot find instruction 0xFFFFFFFE (I'm guessing it tries to start, reads an unprogrammed vector table filled with an erased flash's 0xFFFFFFFFs and tries to branch to a thumb instruction at 0xFFFFFFFE).

Any suggestions on why this is not working?

Possible thinking is I'm missing a jumper -OR- I'm using Mini-USB instead of Micro USB (I couldn't get Micro-USB to power).

Thanks,

Roger

Ok, P&E Microcomputer Systems website says that there the "Device is secure" message is a red herring meaning the device may not be powered/talkable-to from the OSBDM/OSJTAG. I will try to verify connectivity.... wondering if I mis-set a jumper. Or if I have the wrong version of gdbserver talking to that pseudo-jtag chip?

Hello Roger:

Seems that the selected device is wrong.

Try changing this:

Thanks- That was it. I'm still getting used to Freescale grouping peripheral features by processor speed.

General suggestion for anyone reading this... don't ignore the number after the Package Code.... you may have to try all the different reasonable selections.
