When I try to create a generic layout, the STM32CubeMX cannot find a clock solution for any configuration without an external input frequency. It basically says that PLL Source Mux should be HSE.

Should I enable HSE for the generic board or should I try to ignore the warning given that it reaches 48MHz for USB, etc.

I also do not know where to grab the pinout definitions for the specific board. Theguide I am using does not specify how to add a specific board, it cuts off after adding the generic board.

Hi@otac0n

Should I enable HSE for the generic board or should I try to ignore the warning given that it reaches 48MHz for USB, etc.

No, generic have to use the internal clock only. If user wants to use HSE then he have to redefine the system core clock config at sketch level.
Dedicated variant can defined by default the HSE if they have one as the hardware is known.

I also do not know where to grab the pinout definitions for the specific board. Theguide I am using does not specify how to add a specific board, it cuts off after adding the generic board.

Well in general at least the Arduino connector have top be properly defined D0-D15 and A0-A5 but this Disco has no Arduino connector so you can simply defined them following each connector.
For Example:

/* P1 connector right side */#definePC1 0#definePC3 2.../* P1 connector left side */#definePC1 19

Or
For Example:

/* P1 connector */#definePC1 0#definePC3 1...

You can refer to this one as example:
https://github.com/stm32duino/Arduino_Core_STM32/blob/main/variants/STM32F4xx/F407V(E-G)T_F417V(E-G)T/variant_DISCO_F407VG.cpp
https://github.com/stm32duino/Arduino_Core_STM32/blob/main/variants/STM32F4xx/F407V(E-G)T_F417V(E-G)T/variant_DISCO_F407VG.h

So you have to create the variant_DISCO_F411VE.*

So, I have

• generated and copied the ldscript.ld
• generated the clock code for Generic and for the DISCO_F411VE variant.
• copied the variant_generic.c/h files to make variant_DISCO_F411VE.c/h
  • reordered and renumbered the pins in the same order as the DISCO_F407VG board
  • updated LED, BUTTON, SPI, and I2C sections.
  • defined HAL_DAC_MODULE_ENABLED

That puts it on par with the DISCO_F407VG. Let me know what steps can be taken to validate these files on hardware.

You can use this examples to check if the pin mapping is correct:

I had to order a USB Serial connector to test this out. Using the generic variant I get this:

#####NUM_DIGITAL_PINS = 81NUM_ANALOG_INPUTS = 16#####Checking digital pins...End check digital pins#####Checking analog pins definition...End check analog pins#####Checking IP instances (I2C, UART, SPI)...End check IP instances (I2C, UART, SPI)############################################ Test PASSED########################################

Using myvariant_DISCO_F411VE I get errors that I'm unsure where they originate:

<path>2.11.0\libraries\SrcWrapper\src\stm32\analog.cpp:340:17: error: 'DAC_CHANNEL_1' was not declared in this scope; did you mean 'ADC_CHANNEL_1'?<path>2.11.0\libraries\SrcWrapper\src\stm32\analog.cpp:364:6: error: variable or field 'HAL_DAC_MspInit' declared void...

Edit: Fixed that. Now it just locks up due to bad clock config?

I will say that I had trouble following step 1 here:https://github.com/stm32duino/Arduino_Core_STM32/wiki/Using-git-repository

OK, with a change toRCC_HSE_ON (instead ofRCC_HSE_BYPASS) my board passes the tests.

I believe this to be ready, but I would appreciate a critical look-over as this is my first Arduino board.

Yesterday, I've made a review and force push on your branch to fix all the issue you made 😉
But forgot to warn you.
To sum up: no DAC, HSE on instead of bypass.

Will end review this morning.

I had to order a USB Serial connector to test this out. Using the generic variant I get this:

You can simply connect the default Serial to the STLink. SB10 and SB11 not fitted on the board,if you add SB then you will have the VCP functional.

I've pushed some updates on your branch.
