Re: Can not initialize STM32L476 UART

Hi Jimmo, Thanks again, that combination is one I did not try ie It's Ctrl-a, then just k, then just y. It Worked!!!! Did you type "AT" yourself? Otherwise it sounds like your computer is trying to connect to the device as a modem. Ubuntu has a thing called modemmanager which you should disable (or ...

Re: Can not initialize STM32L476 UART

Tried all those and it must just be my luck, as usual, they do not work. Start RETL as before (screen /dev/ttyACM0) starts but with errors; MicroPython v1.11-575-g258b14783-dirty on 2019-11-12; NUCLEO-L476RG with STM32L476RG Type "help()" for more information. >>> >>> AT Traceback (most recent call ...

Re: Can not initialize STM32L476 UART

Hi Jimmo, "make -j BOARD=NUCLEO_L476RG -the screen rolled with error messages for about 20 minutes " Was my error, I was looking at the # as a remark but that is wrong when it is a define in c, some sort of directive for the compiler. Once I realised this I changed the lines as you suggested ie Code...

Re: Can not initialize STM32L476 UART

Hello Jimmo I plugged the NUCLEO into my linux box via the USB mini connector with the ST Link jumpers on and BOOT0 disconnected. I followed your instructions; # from wherever you cloned micropython: cd mpy-cross -easy make -j -did something cd ../ports/stm32 -easy make submodules -did something loo...

Re: Can not initialize STM32L476 UART

Hi Jimmo, Thanks for your help, it is keeping me sane. I have connected the nucleo directly to a USB cable ie PA11 to D- and PA12 to D+ Using both windows and linux. I managed to transfer the newly compiled dfu file using the windows dfu utility. If I plug the NUCLEO in via the mini USB plug, my lin...

Re: Can not initialize STM32L476 UART

Well that did not work, I now can not 'screen' to the board. Nor does the board show up as ttyACM0. Have to go.

Re: Can not initialize STM32L476 UART

Hi Jimmo, There has got to be a better way! This really is a complex maze. I have installed so much onto this computer and now believe that we have sufficient tools on this computer to compile but insufficient brain cells to use it! Found a github page that I coul sort of follow. https://github.com/...

Re: Can not initialize STM32L476 UART

Hi Jimmo, Thanks for your reply. I had a look at the files you linked ie micropython/ports/stm32/boards/NUCLEO_L476RG/mpconfigboard.h and micropython/ports/stm32/boards/NUCLEO_F091RC/mpconfigboard.h So then read a post/entry (https://forum.micropython.org/viewtopic.php?f=12&t=2613) to try and compil...

Can not initialize STM32L476 UART

Hello All, I finally got the NUCLEO_L476RG-20191107-v1.11-563-g4be316fb0.dfu on to my Nucleo STM32L476. using screen I can access the REPL! I followed the tutorial and got the LED to flash and do other things. The Nucleo-64 STM32L476RGT6 has a UART on pins PA2 PA3. PA2 USART2_TX PA3 USART2_RX This i...
