This is an automated email from Gerrit. Tomas Vanek (va...@fb...) just uploaded a new patch set to Gerrit, which you can find at http://openocd.zylin.com/4059 -- gerrit commit d7d188a082efaabf2dd6ee8412f1cddfed09f30e Author: Tomas Vanek <va...@fb...> Date: Fri Mar 10 21:43:46 2017 +0100 flash Kinetis: add KL28 device This device differs a lot from others in KL series. Unfortunately System Integration Module, where device identification resides, moved to new address so probe now have to try both addresses of SIM_SDID. Introduce a new bank creation option: -sim-base to ensure error free probe. WDOG32 is slightly different from KE1x and on different address. System Mode Controler changed layout to word aligned.
