Im a very beginner in embedded system,
i use it only for hobby, a learnd c last year and its very very beautifull to programming on Kinetis MCU and i dont like to swicht to other platform, a lot of people write about documenation of kinetis but i love it :smileyhappy: its nice !
I have now a kwikstik (with J-Link interface) and make me now a second buy-list for my hobby and need your help !
My first buy list is not really working.
I have a idea for a good friend and i will finish my project on my pcb.
I try last days to flash K04Z in tssop package to flash / erase via SWD KWIKSTIK, but J-Link can not find the mcu (i try it with extra power supply too.)
And now my question for my buy-list :smileyhappy:
Its possible to flash / debug a single chip on breadboard, no dev board (if i buy it from distributors like mouser or digikey ...)
wich hardware i need to do it simpel
i think its possible, i see a lot of tutorial about stm32 :smileysad: but not for Kinetis..
PLEAS HELP !
Thank you !
Alex
Hi Alex,
yes, you don't need a dev board to program/flash a device. It is so basic that's why you even don't need a tutorial :-):
All what you need is to power the microcontroller and connect it to the SWD debug connector. So you need:
- Vcc (I assume 3.3V)
- GND
- Pull-up the reset pin to Vcc (10k Ohm) and ideally a 100nF to GND
On the debug connector you need:
- SWD DIO
- SWD CLK
- GND
- Vcc
- Reset
I hope this helps,
Erich
Hello Erich thank you very very much :smileyhappy:
i make a new order of KE04Z and try it again :smileyhappy: the TSSOP - Package is nice to plant to pcb :smileyhappy:. I damaged the first order :smileyhappy: i think i was wrong with pin counting :smileyhappy: .
I make a circuit can you take a look.
About J-Link i dont need OpenSDA ? Like FRDM Boards ?
I think in my buy list is a FRDM board not wrong, Kwikstik is complicate to use pin (pci express 164 slot )
I read all day your blog (mcu on eclipse) <- very nice ressource ! i use your diy toolchain kippler :smileyhappy:
THANK YOU !
Hi Alex,
you can use the Kwikstick as programmer/debug tool (see Using the KwikStik K40 Board to Debug an external Board | MCU on Eclipse ), but if your project is hobby/non-commercial I recommend you get a J-Link EDU Mini (J-Link EDU Mini | SEGGER - The Embedded Experts ) which should be available from your distributor (Farnell or Mouser for example).
That way you don't have to use any OpenSDA.
Erich
Thank you Erich! Is my circuit okay ?
