Hi,
I'm trying to debug a custom board with a MKE02Z64VFM4 with the Kinetis Design Studio 2.0 and a CMSIS-DAP JTAG.
I'm facing an issue when downloading a simple application created with KDS "Create new project" wizard. The result is that the MKE02 cannot be programmed because " Cannot access device, device is secured. Mass erasing a device will unsecure it until the next reset. To permanently unsecure, mass erase then flash a program containing an appropriate flash configuration field.". And then KDS ends the debug session.
Note that working with KEIL uVision, with the same JTAG and a GPIO demo from Freescale, the MKE02 works OK and can be reached by the JTAG an debugged with no problems. But for other reasons I cannot develop the final project using KEIL.
This is the complete output from KDS, executing OpenOCD with the "-f kinetis.cfg --debug 4" parameters (full debug output). The bold at the end was added by me.

Info : 202 527 cortex_m.c:1810 cortex_m_examine(): Mass erasing a device will unsecure it until the next reset. To permanently unsecure, mass erase then flash a program containing an appropriate flash configuration field.
Trying to understand more I've downloaded the KDS 2.0 source code (http://cache.freescale.com/lgfiles/KDS/KDS-v2.0.0-source-files.zip?fpsp=1&WT_TYPE=IDE%20-%20Debug,%2...) to see the modifications Freescale has made to OpenOCD to enable MKE devices support.
Looking at the patch file openocd-0b26376_kds-2.0.0.patch I've noticed that OpenOCD was modified to do the following:
retval = target_read_u8(target, FSEC, &fsec);
if (retval != ERROR_OK) {
LOG_ERROR("Cannot read FSEC. Device may be secured");
LOG_INFO("Mass erasing a device will unsecure it until the next reset. "
"To permanently unsecure, mass erase then flash a "
"program containing an appropriate flash configuration field.");
exit(-1);
}
else if ((fsec & 0x3) != 0x2) {
LOG_ERROR("Cannot access device, device is secured");
LOG_INFO("Mass erasing a device will unsecure it until the next reset. "
"To permanently unsecure, mass erase then flash a "
"program containing an appropriate flash configuration field.");
exit(-1);
}
But FSEC, on the same patch, is defined as
#define FSEC 0x0000040C
I know other Kinetis devices have the Flash Security Byte located at 0x40C, but for the MKE02 it's different:
So the question is: Is KDS 2.0 enabled to debug MKE02 devices with OpenOCD with CMSIS-DAP?
Has anyone managed to work and debug with said configuration?
Thank you.
