Martin, thanks for working on this issue. Could you please submit the patch to our gerrit at https://review.openocd.org See https://openocd.org/doc/doxygen/html/patchguide.html for details.
IMO we should detect "Initial Product Rev" (Z part) more precisely. I browsed Freescale docs and "Initial Product Rev" exists for KINETIS_K_SDID_K10_M100, KINETIS_K_SDID_K20_M100, KINETIS_K_SDID_K30_M100, KINETIS_K_SDID_K40_M100, KINETIS_K_SDID_K60_M100 and also for K50 M100 never supported in OpenOCD I found a doc relevant to SIM_SDID REVID https://www.nxp.com/docs/en/engineering-bulletin/EB782.pdf I would guess by mask set names that only revision number 1.0 (REVID 0) is "Initial Product Rev" Also see a similar doc for K22F which doesn't have any "Initial Product Rev" https://www.nxp.com/docs/en/engineering-bulletin/EB811.pdf The lowest REVID is 1 so it looks like we can just check for REVID 0 to detect "Initial Product Rev". Unfortunately Freescale doesn't publish revision lists of all Kinetis devices so my guess might be wrong. To be safe from a possible regression I would prefer checking for REVID 0 on the devices listed above. --- ** [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 01:27 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. --- Sent from sourceforge.net because openocd-devel@lists.sourceforge.net is subscribed to https://sourceforge.net/p/openocd/tickets/ To unsubscribe from further messages, a project admin can change settings at https://sourceforge.net/p/openocd/admin/tickets/options.
