Hi Tom, You are right and I will be looking into that and a whole raft of other issues on the K22FX512 Preamp Project. The Low Power operation in particular is not working at all. I inherited this project which is based on Arduino and more specifically on a hack of Teensy. The K22FX512 is not covered by Teensy so I have a bit of work to do. Previously a Teensy board was used as an EzPort programmer but of course this results in a lack of debug capability, Whilst I will continue to use the Arduino...

Hi All. I have had a successfull day. Did a lot of reading and found the flashconfig code attribute ((section(".flashconfig"), used)) const uint8_t flashconfigbytes[16] = { 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, FSEC, FOPT, 0xFF, 0xFF }; I set FSEC to 0xFE and FOPT to oxFF and rebuilt the BlinkBlue2 to verify all was in order. I then built BlinkBlue1 (start addr 0x000) and programmed tje flash with the following results :- noel@DESKTOP-0AFLL5T MSYS /w/arduino1-1812/portable/sketchbook/BlinkBlue1/build...

Hi all, I am going to have a rest now as it is after 11PM and I started at 8AM today. I shall attack this with renewed gusto in the morning. Thanks and regards. Noel.

Hi Paul, Thank you for the instructions. This is proving to be a great learning exercise for me, I have carried out the git fetches and done a MAKEPKG-mingw PKGBUILD on the results. I now get the following when I program the flash :- noel@DESKTOP-0AFLL5T MSYS /w/arduino1-1812/portable/sketchbook/BlinkBlue1/build $ openocd -f interface/ftdi/olimex-arm-usb-ocd.cfg -f target/kx.cfg -c "program BlinkBlue1.ino.bin erase verify 0x0000" Open On-Chip Debugger 0.10.0+dev-01293-g7c88e76a7-dirty (2020-07-02-20:47)...

Hi Tom, Finished dinner and back again. I have done a clean build of the latest sources from https://git.code.sf.net/p/openocd/code The log now says :- noel@DESKTOP-0AFLL5T MSYS /w/arduino1-1812/portable/sketchbook/BlinkBlue1/build $ openocd -f interface/ftdi/olimex-arm-usb-ocd.cfg -f target/kx.cfg -c "program BlinkBlue1.ino.bin erase verify 0x0000" Open On-Chip Debugger 0.10.0+dev-01293-g7c88e76a7-dirty (2020-07-02-20:47) Licensed under GNU GPL v2 For bug reports, read http://openocd.org/doc/doxygen/bugs.html...

Hi Tom. Ok. I am about to have dinner and a break. I will try it out and report back the results tonight (Melb Time). Thanks again for your efforts. Noel.

Hi Tom. I have just switched on my Lockdown lab set up on the dining room table and saw this great news from you. This is a lifesavour as I was in danger of going totally mental. I have read the Kinetis documentation many times over and my only conclusion is that the guy that wrote the manual needs to go back and have some lessons in Technical Writing. You have provided a lot of detailed information so now I will go off and learn more about programming the FCF Block. I have noted your suggestion...

Hello Tom, Nice to hear from you again. I have attached the files. BlinkBlue1 = 0x0000 start address and BlinkBlue2 = 0x4000 address Cheers Noel
