Running ucnc on NUCLEO-F411RE (STM32F411RET6)???

I added board support to the project, such as STM32F4-Blackpill-F411CE.
That is, changes in files:

I compiled the project and uploaded it to NUCLEO-F411RE the LED is blinking (ACTIVITY_LED) on Windows 10 "Unknown USB device" appears and error code 43

What should I do to make UCNC work? Please help and advice

[Paciente8159]

Thanks for the report.
I don't have a Nucleo board but I will investigate. I'll give you feedback

[Paciente8159]

I can't seem to find my F411 blackpill.
I spot a potential problem in your config.
this line

build_flags = ${common_stm32.build_flags} -D BOARD=BOARD_NUCLEO_F411RE

replace it by

build_flags = ${common_stm32.build_flags} -D BOARD=BOARD_BLACKPILL

The overrides and the stm32.ini changes will enforce your configurations. Just maintain the µCNC boardmap definition.
Please retry. I will try to find my BlackpillF411 it in the meantime and do further testing.
By the way did you test the UART port? Was it communicating or muted also?

Another question is where are you placing this code?

[andy0983]

I changed it to "build_flags = ${common_stm32.build_flags} -D BOARD=BOARD_BLACKPILL"

USB still has error code 43 (USB\VID_0000&PID_0002\5&165ECDDA&0&2)
USB communication connection:
Nucleo board - USB cable
PA12(USB_DP) - USB Data
PA11(USB_DM) - USB Data
GND - GND
U5V - 5V

UART - after connecting and pressing (reset), this pops up
Grbl 1.8 [uCNC v1.8.7 '$' for help]
client>$$

:ok
:ok
$0=10,000 (Step pulse time, microseconds)

and accepts Gcode commands. so it works

I am attaching the log from the software upload:

"Another question is where are you placing this code?"
I do not understand the question.
Which code are you talking about??

[Paciente8159]

I found my blackpill f411.
I will try to test your config tomorrow despite being a different version from the one used in your board.

"Another question is where are you placing this code?"
I do not understand the question.
Which code are you talking about??

I mean..in which file did you places the changes? In the files indicated in the comments?

[andy0983]

yes, I added new code in these files
//////// stm32.ini - adding ///// ////

[Paciente8159]

Ok I tried your configuration and got a few errors.

Has explained keep the blackpill definition on the the stm32.ini like stated above

build_flags = ${common_stm32.build_flags} -D BOARD=BOARD_BLACKPILL

Also remove this line from the boardmap_override.h

#define BOARD BOARD_NUCLEO_F411RE

And correct this line

#define BOARD_NAME F411RE

to this

#define BOARD_NAME "F411RE"

Also for now comment the whole part of the SPI pins for now. I think I need to fix the mcumap core file

//#define SPI_CLK_BIT 3
//#define SPI_CLK_PORT B
//#define SPI_SDI_BIT 5
//#define SPI_SDI_PORT B
//#define SPI_SDO_BIT 4
//#define SPI_SDO_PORT B
//#define SPI_CS_BIT 0
//#define SPI_CS_PORT B

And retry to upload like that

[Paciente8159]

I've patched the SPI problem with the incorrect alternate function settings of the pins here #622 .
By the way, and according to the STM32 datasheet you have SPI_SDO and SPI_SDI pins swapped. Also the SPI_CS pin is not valid. But you will only need the CS pin if you plan on using the SPI in slave mode.

[andy0983]

I took a clean design.
I added it to the stm32.ini file
[env:NUCLEO-F411RE]
extends = common_stm32
board = nucleo_f411re
upload_protocol = stlink
build_flags = ${common_stm32.build_flags} -D BOARD=BOARD_BLACKPILL

I copied the files with corrections written in the post above
boardmap_override.h
boardmap_reset.h
cnc_hal_overrides.h
cnc_hal_reset.h

Next, USB, error code 43.

I did tests with such settings
[env:STM32F4-Blackpill-F411CE]
extends = common_stm32
board = nucleo_f411re
upload_protocol = stlink
;board = blackpill_f411ce
;upload_protocol = dfu
build_flags = ${common_stm32.build_flags} -D BOARD=BOARD_BLACKPILL

Next, USB, error code 43.
Tomorrow I will buy a new USB cable and test it again.
I can send you such a nucleo f411re board

[Paciente8159]

Tomorrow I will buy a new USB cable and test it again.

Please let me know if it worked. I don't think beside the pin count and extra drivers there is not much difference between mine 411CE and your 411RE.

I can send you such a nucleo f411re board

That would be great and I deeply appreciate the offer. But lets see how it works with the cable.
If it fails I can try to draft a test using Arduino USB library to see if it solves.
Thanks

[andy0983]

Works :)
The error was the wrong connection of the USB 5v power supply, it was connected to U5V and should have been to E5V

I am sending the correct connection.

USB D+ (green wire) to PA12
USB D- (white wire) to PA11
USB 5V to E5V
USB gnd to GND
Jumper on E5V
Jumper on boot0 and VCC (pins shorted only when uploading the software using the dfu / stlink protocol)

[andy0983]

Paciente 8159, please contact me by e-mail to send the Nukleo F411re board

[Paciente8159]

Again thank you for your offer. As I said the nucleo chip is very similar to the blackpill with f411 with an attached st-link.
I have several bluepills, blackpills, st-links and cmsis-daps...so currently I am not in the need of such board.

But again thank you for your kind offer.

EDIT
I will add the boardmap for shield v3 on this. Users can then expand on additional pinout needs.

[Paciente8159]

Merging PR #628.
Let me know if you find any issue in the future
