Thanks for the fast reply! I will submit this to Gerrit once I have addressed your \
first comments.
About the REVID: The interface switch was done between Revision 1.x and 2.x. This is \
described in this NXP document:
https://www.nxp.com.cn/docs/en/application-note/AN4445.pdf
My MK60 chip has the part number MK60DN512ZVMC10 and REVID = 7. The very first \
revisions 1.0 to 1.2 were not even called MK60 but PK60 but without a "Z" in the \
part number. The "Z" in the mask set obviously does not correspond to the "Z" in the \
part number at all. NXP made a fine mess here...
Still, the KL series should not be affected by my change at all. They seem to end up \
in the "Newer K-series or KL series MCU" branch of the if condition testing the \
KINETIS_SDID_K_SERIES_MASK.
Anyway, if only the KL series needs switching the VLPR to RUN mode, maybe we could \
just remove the entire check for the older K-series MCUs. This would eliminate the \
need to discriminate between the REVIDs at all. I would probably do that by \
introducing a new field in the kinetis_chip struct controlling whether \
kinetis_check_run_mode() shall check the pmstat at all.
Do you agree this may be the better approach? Or is it important to check also on \
K-series whether the MCU is in normal RUN mode for extra reliability?

** [tickets:#236] Cannot flash Kinetis Z parts**
**Status:** new
**Milestone:** 0.9.0
**Created:** Thu May 02, 2019 09:41 AM UTC by Ramy
**Last Updated:** Fri May 27, 2022 03:55 PM UTC
**Owner:** nobody
I am using a Kinetis MK20DN512**Z**VLQ10 which is an earlier version of the \
MK20DN512VLQ10. Flashing the non-Z part works fine in OpenOCD 0.10, but when flashing \
the Z part, the following error occurs: "Flash operation not possible in current run \
mode: SMC_PMSTAT: 0x0"
It looks like the code in the kinetis_check_run_mode function reads the SMC_PMSTAT \
register on the target device to check that it is in run mode. This register does not \
exist on the earlier revision K20 device, so pmstat is always 0 and OpenOCD refuses \
to program the device.
I have attempted to use earlier versions of OpenOCD which don't have this check, but \
they fail when trying to flash either device.
