Re: How to debug MicroPython using gdb ?

I tried to add in the samd Makefile

Code: Select all

LDFLAGS += --gc-sections --specs=rdimon.specs -lrdimon
but got:

Code: Select all

LINK build-ADAFRUIT_PYGAMER/firmware.elf
arm-none-eabi-ld: unrecognized option '--specs=rdimon.specs'
and l could not find librdimon.a in the toolchain...

Re: How to debug MicroPython using gdb ?

Ah! I was thinking that was magic, any printf output would be redirected to the debugger :) So yes if this is not magic I guess I need semi-hosting. Do you know in the samd makefile where I should add those linker directives : -specs=rdimon.specs and -lrdimon And where (+ includes ?) to add : void i...

How to debug MicroPython using gdb ?

Hi, I tried to debug some SPI/TFT driver code for the SAMD port and I never used gdb for remote debugging. My first wish was to "only" see my printf somwhere (occuring before the REPL comes to life) but... nothing showed up. I'm using the J-Link EDU Mini connected to the SWD port of my Adafruit Pyga...

Re: Need help with Makefile for ATMEL SAMV7

Don't get too excited yet Too late! I'm excited!!! Yeah, I love how Adafruit/CP have picked up and run with MicroPython - and I understand their need to fork and even many of their decisions to modify certain features to better support beginners. But I do feel like both projects have missed an oppo...

Re: Need help with Makefile for ATMEL SAMV7

Mattyt, I asked a similar question on Adafruit CP forums (https://forums.adafruit.com/viewtopic.php?f=60&t=152352), what would it mean to havd a minimal support of SAMD based boards on MicroPython. Looks like that's not an easy task. :roll: Do you think that will happen ? I have both SAMD and STM32 ...

Re: [Any STM32 board] How much time this loop should take ?

Is your code available someplace (i.e github) that I can build for a 401 board with a known HSE crystal and compare results? I'm fairly certain (based on other threads, and the values he's quoted that match) that they're working from: https://github.com/KittenBot/micropython_meowbit/blob/uf2/ports/...

Re: [Any STM32 board] How much time this loop should take ?

Also, maybe a bit of a long shot, but back to the MCO idea -- you said "my logical analyzer doesn't have enough bandwidth I presume". What do you have? Can you set the divider down low enough? Like you just need a pulse counter? Any other dev boards sitting around? I have this one: https://referenc...

Re: [Any STM32 board] How much time this loop should take ?

Ah !!! I did not know this tool! I spent hours on an speadsheet to do something similar (but not as good for sure...) Nice tool, I updated the config to have the good APBx prescaler and SYSCLK: clock.png Same "warning" but that' s so weird as the board works and the USB too with those settings. to f...
