EFM32HG Dev Kit #4

Closed Brando753 closed 7 years ago

Brando753 commented 7 years ago

I seem to be having some problems getting the sample blinky program to run on this board I created a new repo and added efm32-base as the submodule, copied the CMakeList file and updated it to use the EFM32HG322F64 device and updated it to point to the new efm32-base location. I copied over the source directory and only modified the macros to look like:

#ifndef LED_PIN
#define LED_PIN     4
#endif
#ifndef LED_PORT
#define LED_PORT    gpioPortF
#endif

which should be the EFM32HG kits correct port and pin for one of the two led's. I then created a build directory ran cmake .. followed by make and make flash (using the Jlink configuration) and it uploads to the board; the problem is however is the board will not blink the light as expected. Cmake:

So the first thing I think to do is alright spin up the debugger so I create two shells, one I run cmake debug-server and the other I run make debug in GDB I run monitor reset halt followed by break main followed by continue however it never breaks.

I also tried deleting build and recreating it with both the commands cmake -DCMAKE_BUILD_TYPE=Debug .. and cmake -DCMAKE_CXX_FLAGS_DEBUG=-g3 -DCMAKE_BUILD_TYPE=Debug .. followed by rebuilding and reflashing however that made no difference. Any ideas or would be great cause I am not sure where to go from here...

ryankurte commented 7 years ago

The HG is a Cortex-M0, which I don't have / haven't tested. I suspect the compiler / linker options are not configured correctly for the target. It might be that something in the startup script is accessing unaligned memory or using an invalid instruction and causing a hardfault, though usually you would be able to break (or interrupt) the debugger and see that IIRC.

Weird that you're not getting /anything/ from the debugger. Can you dump a line from the output of a make VERBOSE=1 so we can have a look at the command that's actually being called?

Brando753 commented 7 years ago

Yea no problem, I removed build, recreated cmake file and then run make VERBOSE=1:

ryankurte commented 7 years ago

So these are the important bits for the compile step.

-DEFM32HG322F64 
-std=gnu99 -Wextra -Wall -Wno-unused-parameter 
-mcpu=cortex-m3 -mthumb -mfix-cortex-m3-ldrd
-fno-builtin -ffunction-sections -fdata-sections -fomit-frame-pointer 
--specs=nano.specs -MMD -MP 
-O0 -g -gdwarf-2

The cpu configuration is -mcpu=cortex-m3 -mthumb -mfix-cortex-m3-ldrd but should be (something like) -mcpu=cortex-m0 -mthumb

CPUs are identified here based on the device family name. If you add the following case to that block (then remove all build cache and re-run everything) you should see that change, and if nothing else is broken it will hopefully boot.

elseif(CPU_FAMILY_U STREQUAL "EFM32HG")
set(CPU_TYPE "m0")
set(CPU_FIX "")

See how that goes and let me know?

Brando753 commented 7 years ago

Yea that did it, seems to now program and flash correctly, however the debugger still wont break at anything on main when I set break points there followed by monitor reset halt and continue is it being optimized out? I applied a camke cmake -DCMAKE_CXX_FLAGS_DEBUG=-g3 -DCMAKE_BUILD_TYPE=Debug .. but it made no difference...

Brando753 commented 7 years ago

Worth noting that I can set a break point and successfully break at the SysTick Handler and the Delay Function, but I cannot break before the Delay function, which is why I was thinking it might be being optimized out. I can also get a back trace so I can interact with the debugger, just not break anywhere in main.

ryankurte commented 7 years ago

So the led flashes, but you don't get hit the breakpoint at main?

You can see the debug options are being passed through in the paste above (-O0 -g -gdwarf-2 is no-optimisation, include debug, and use dwarf2 debug symbols which should be all).

IIRC there is some weirdness with the ways that some debuggers handle monitor reset halt, but I can't remember what the solution is :-/ You might be able to jump to Reset_Handler to fake a restart / see if it hits main there.

Brando753 commented 7 years ago

yea that seemed to do it, interesting to note, never had to fake a restart like that before, but with that it seems to work. Should I put a pull request for the one line fix or are you going to push it through?

ryankurte commented 7 years ago

Thanks for the PR!

I have had it with some debug adaptors / drivers / devices and not others. One day I will have to follow it up / solve it properly.

Brando753 commented 7 years ago

Hey thanks for being so helpful with all of this! Once I get some time to follow up I will hope to get openocd working and I can see if the issue follows through with openocd or not. Once I finish up this project, I will start my next one which uses the EFR32 family.
