eclipse - Programming SAM uC family without ATmel Studio -

-

i've asked question on :https://electronics.stackexchange.com/ no success, i'm trying luck here.

i've designed board used sam uc (cortex m0+). don't want use atmel stduio, want learn how use eclipse , arm-gcc , openocd ( still can't understand, 1 ?). question possible , if yes, has hint how can proceed ?

i've installed 3 parts,and farthest get: enter image description here

i agree notlikethat, cant figure out.

1) yes, have dozens or hundreds of bare metal microcontroller examples use gnu toolchain, no ides, command line. no problems there whatsoever.

2) openocd open source tool knows how speak on chip debuggers, in particular arm ones. , supports jtag , swd cortex-m0+ have if exposed (which is).

3) sam microcontroller there hundreds of different ones on decade or so, cortex-m0+ narrows down more thousands more hundreds of different ones. narrow down @ least 1 family. popular samd21? have used 1 of those, , using openocd , gcc quite doable without need ide anyone. add text editor.

i prefer use $10 st discovery or nucleo board swd debugger, remove couple of jumpers , can use st-link front end other microcontrollers st or not st.

the chip documentation google show how hook , talk chip.

do have raw chip or have on board, 1 made or 1 bought?

your question equivalent of, have ford, , dont know size brake pads need , have have dealer install them.

is truck car, one, how many models/variations have had in last hundred or years? sizes/parts in manual. , latter yes of course can yourself, or have else install them, dont have go dealer.

i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response...
