Codewarrior 10.2 programs flash in Kinetis 100x slower than MCU 10.1. Using J-link

[deuteron]

We just upgraded from MCU 10.1 to MCU 10.2. We run and debug programs in a Kinetis K10 out of internal flash. We use a J-link version 8.0 or a Kwik-stik for download. Programming the flash takes about 2 seconds with 10.1 but over 3 minutes with version 10.2. This has been tried on different computers, all use Windows 7. Are we doing something wrong? Is this a know issue? Need some suggestions

With CW-MCU 10.1, the defauslt J-Link setting is "Auto" but the default for CW 10.2 is "fixed". To change the speed:

Main menu -> Run -> Debug Configurations -> Main -> Connection -> Edit -> JTAG/SWD speed -> Auto.

Then it loads at the proper speed.
