Helllo, Thanks for the huge quantity of work!

I would like to know if you plan to include in the release 1.7.0 these generic variants for F401

STM32F401CC in UFQFPN48 and LQFP64 packages

STM32F401RCT6 in LQFP64 package

Generally speaking how do you handle the different packages versions?

pkourany commented 5 years ago

@mrguen, I have the RCT6 variant working on my system with v1.61 but haven't create a PR yet. I you want the variant file package and changes boards.txt file, I can post it.

mrguen commented 5 years ago

@pkourany Oh, Thanks a lot. That would be nice of you.

pkourany commented 5 years ago

Here is the working RCT6 variant. I have attached a zip of the variant folder. Do not rename this folder. The following needs to be added to the boards.txt file under the Generic F1 section of the file:

# Generic F103RCT6 board
GenF1.menu.pnum.GENERIC_F103RC=Generic F103RCT6
GenF1.menu.pnum.GENERIC_F103CB.upload.maximum_size=262144
GenF1.menu.pnum.GENERIC_F103CB.upload.maximum_data_size=49152
GenF1.menu.pnum.GENERIC_F103CB.build.board=NUCLEO_F103RB
GenF1.menu.pnum.GENERIC_F103CB.build.product_line=STM32F103xE
GenF1.menu.pnum.GENERIC_F103CB.build.variant=GENERIC_F103RCT6

GENERIC_F103RCT6.zip

You should review the pin used for an onboard LED the variant.h file. The included variant.h file specifies PA15 for the LED.

mrguen commented 5 years ago

Ok, Thanks Paul. The issue was open for STM32F401... I don't know if these files might help for the RCT6 type...

pkourany commented 5 years ago

Oh boy. I must have dyslexia cause I read F103RCT6 somehow! I'm going to hide that post since it isn't relevant.

BTW, a lot of the work is done by STM32CubeMX by creating a project for the MCU/package you want, configuring the clock for internal/external crystals and creating the code for that variant you want. From this, you can get the code to copy to the ldscript.ld file and the clock configuration code (from main.c) to place in the variant.c file. The PeripheralPins.c and PinNamesVar.h files for all variants can be obtained here. The variant.c and variant.h files can be adapted to a simple list of pin names.

variant.h
#define PA0   0
#define PA1   1
... for all GPIO pins on package

varian.c
const PinName digitalPin[] = {
  PA_0,  //D0
  PA_1,  //D1
  PA_2,  //D2
... for GPIO pins in package

You will also need to review other #defines in variant.h to match the pin counts, # of analog pins, LED pin, etc.

The last thing is to add the variant to the boards.txt file so it appears in the menu.

mrguen commented 5 years ago

Ok. I tried to do it by following your method and https://github.com/stm32duino/wiki/wiki/Add-a-new-variant-(board)

A) ** There was a compilation problem because the board is not considered in Arduino15\packages\STM32\hardware\stm32\1.6.1\system\Drivers\CMSIS\Device\ST\STM32F4xx\Include\stm32f4xx.h

So I added

if defined(STM32F401xC)

include "stm32f401xc.h"

and uncommented #define STM32F401xC

B) ** I modified boards.txt as :

@mrguen can you zip your variant directory and share here?

mrguen commented 5 years ago

Here it is: STM32F401RCT6.zip

boards.txt

mrguen commented 5 years ago

Here is what I have done :

1) Copy C:\Users\TG\AppData\Local\Arduino15\packages\STM32\hardware\stm32\1.6.1\variants\board_template to C:\Users\TG\AppData\Local\Arduino15\packages\STM32\hardware\stm32\1.6.1\variants\STM32F401RCT6

2) In STM32CubeMX Used the default settings for STM32F401RC but changed

the clock for HSE / Crystal/Ceramic, set 8 MHz crystal M=4 PLL= 168 P=4 Q=7 SYSCLK = 84 MHZ AHBPrescaler = 1 APB1Prescaler = 2

· Activated USART1 Asynchronous · Activated SPI1 / Full Duplex master · Activated USB / OTG/Dual role device Generated the code for SW4STM32

3) Copied STM32F401RCTx_FLASH.ld to ldscript.ld

4) Copied SystemClock_Config(void) from the generated main.c to variant.cpp

5) Copied the files PeripheralPins.c and PinNamesVar.h from https://github.com/stm32duino/Arduino_Tools/tree/master/src/genpinmap/Arduino/STM32F401R(B-C)Tx to the STM32F401RCT6 folder

6) Copied digitalPin array in variant.cpp and pin defines in variant.h from NUCLEO_F401RE

In fact I am using this board https://fr.aliexpress.com/item/32894670982.html?spm=a2g0s.9042311.0.0.27426c37RrpWiJ and really don’t know their pin mapping. I have asked them a documentation… I suppose I can manage with the Nucleo numbering. I only changed the BOOT1 that was not considered on the NUCLEO board.

7) Modified boards.txt by adding in the “# Generic F4” section

Secret Garden F401RC

GenF4.menu.pnum.STM32F401RCT6=Secret Garden F401RCT6 GenF4.menu.pnum.STM32F401RCT6.upload.maximum_size=262144 GenF4.menu.pnum.STM32F401RCT6.upload.maximum_data_size=65536 //GenF4.menu.pnum.STM32F401RCT6.build.board=STM32F401RCT6 GenF4.menu.pnum.STM32F401RCT6.build.product_line=STM32F401xx GenF4.menu.pnum.STM32F401RCT6.build.variant=STM32F401RCT6

8) There was a compilation error. I had to add at line 144 in C:\Users\TG\AppData\Local\Arduino15\packages\STM32\hardware\stm32\1.6.1\system\Drivers\CMSIS\Device\ST\STM32F4xx\Include\stm32f4xx.h

if defined(STM32F401xC)

include "stm32f401xc.h"

And uncomment #define STM32F401xC

mrguen commented 5 years ago

The seller sent me the link to the documentation : https://wetransfer.com/downloads/493b7605d31718be87a56133e7cc70d920190814152406/f44f44?spm=a2g0s.imconversation.0.0.7d7a3e5fzulqrL

There is a lot of material. Including an STM32CubeMX project that I used to replace ldscript.ld and · SystemClock_Config()

The compile error is still the same.

Hi @mrguen

I would like to know if you plan to include in the release 1.7.0 these generic variants for F401

STM32F401CC in UFQFPN48 and LQFP64 packages

STM32F401RCT6 in LQFP64 package

There is no plan for this. This is a community project and all contributions are welcome.

Generally speaking how do you handle the different packages versions?

In fact, variant is mainly how you order the pin (pin mapping) and linked to a board. Then the board determines the package used. Anyway a fully generic variant dedicated only to a MCU could be done and then a dedicated entry in the boards.txt could be used to determine the package.

mrguen commented 5 years ago

@fpistm Ok, so if you can help me debug I will provide these...

fpistm commented 5 years ago

About your build issue, as I mentioned you don't have to modify the core files. The include is already present and the define have to be done thanks the boards.txt. https://github.com/stm32duino/Arduino_Core_STM32/blob/6d9575ec6a4452d52a2b0d73656c3a060dd0e2c6/system/Drivers/CMSIS/Device/ST/STM32F4xx/Include/stm32f4xx.h#L160

Using your variant and updating properly the boards.txt there is no build issue. I will provide a branch on my fork with some update.

mrguen commented 5 years ago

1) It's written in the file line 72: "/ Uncomment the line below according to the target STM32 device used in your application /"

@fpistm I tried to configure the device to upload using USB but it seems to be work in progress and I could not do it:

Installed bootloader https://github.com/Serasidis/STM32_HID_Bootloader/releases/tag/2.2.1 via serial

But the PR https://github.com/stm32duino/Arduino_Core_STM32/pull/525 talks about a version 3 !

I suppose PR 525 was patched in 1.6.0 ...

No COM port is enumerated.

fpistm commented 5 years ago

@mrguen you could not use this as the bootloader is for F407 not F401.

mrguen commented 5 years ago

@fpistm ok, so I guess 1) Uploading using only serial 2) asking for a STM32F401 bootloader / I don't know anything about this or can it be easily adapted from STM32F407?

fpistm commented 5 years ago

F4 series include DFU in its builtin bootloader so you can use DFU. See https://www.st.com/content/ccc/resource/technical/document/application_note/b9/9b/16/3a/12/1e/40/0c/CD00167594.pdf/files/CD00167594.pdf/jcr:content/translations/en.CD00167594.pdf

In your case, you should have to set Boot0(pin) = 1 and Boot1(pin) = 0 then plug USB you should be in DFU mode.

For bootloader, I do not manage this. You can try to build your own based on @Serasidis repo or open an issue on his repo.

mrguen commented 5 years ago

Unfortunately I just wrote the HID 2.2.1 bootloader... Also I tried upolad method STM32CubeProgrammer(DFU) but got "STM32_Programmer_CLI.exe not found."

No the builtin bootloader is in ROM. Ensure you are in BL mode. You should see this on windows or under Linux:

fpistm commented 5 years ago

Well, I think you have a driver issue. "STM device in DFU mode" should be "STM32 BOOTLOADER" so probably you installed another driver for DFU.

fpistm commented 5 years ago

You can try the driver provided with the tool: C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\Drivers\DFU_Driver

mrguen commented 5 years ago

Yes, it is working now. It does switch from DFU to USB/CDC after downloading. It is very fast. I could set Serial @ 2 MHz (really?)

fpistm commented 5 years ago

Fine. After upload the STM32CubeProgrammer start your binary. For USB, the speed is not relevant.

mrguen commented 5 years ago

Hello @fpistm !

I am reviewing PeripheralPins.c and I can see that

Some timers functions are defined on two pins but other that could use 2 pins are defined on one pin only. Some timer signals are missing a pin (BKIN, ETR) etc...

Should the timers definition section list all pins/functions possible as referenced in "STM32F401xB STM32F401xC" datasheet?

fpistm commented 5 years ago

The file is generated automatically and provides only used signal. BKIN and ETR are ignored when extracted. If they are required later they could be added. Here all the generated file and script to generate them using CubeMx xml files. https://github.com/stm32duino/Arduino_Tools/tree/master/src/genpinmap

As you can see here only TIMx_CH are kept: https://github.com/stm32duino/Arduino_Tools/blob/5d77a614f11665443f8485733ddd781fb04f8ed0/src/genpinmap/genpinmap_arduino.py#L202

if "_CH" in signal:

mrguen commented 5 years ago

1) There are also CHxN pins defined...

2) What about arbitrating between pins/functions?

For example TIM2_CH1 is defined for PA0 and PA5 while PA0 could be used for TIM5_CH1 which is not mapped.

Can I change it / is there any other impact?

3) Some USART alt pins are not defined (PD5, PD6, PA11, PA12) while USART1 alt pins are.

4) Generally speaking does a pin has to be defined for only one function or for all possible functions ? Example PA_7 is mapped to ADC7, TIM1_CH1N, SPI_MOSI

fpistm commented 5 years ago

1. There are also CHxN pins defined...

Yes as you can see the CHxN are also included as the test check if _CH is contained in the signal name...

2. What about arbitrating between pins/functions?
For example TIM2_CH1 is defined for PA0 and PA5 while PA0 could be used for TIM5_CH1 which is not mapped.

Can I change it / is there any other impact?

Do what you want, the array is also WEAK so you can override it at sketch level to fit your needs and save memory space.

3. Some USART alt pins are not defined (PD5, PD6, PA11, PA12) while USART1 alt pins are.

PA11/12 are for USB so I comment it. PD5/6 does not exist.

4. Generally speaking does a pin has to be defined for only one function or for all possible functions ?
    Example
    PA_7 is mapped to
    ADC7, TIM1_CH1N, SPI_MOSI

If a pin is not connected to dedicated hardware then we could provide all possible functions. If you want use it as SPI then you can or as an ADC...

mrguen commented 5 years ago

Also I just realize that the files you provided are not those from https://github.com/stm32duino/Arduino_Tools/tree/master/src/genpinmap/Arduino/STM32F401R(B-C)Tx

Here is the proposed PeripheralPins.c PeripheralPins.zip

mrguen commented 5 years ago

I see two differences in the ldcript provided as compared to Altium's:

1) possibly missing No _Min_Heap_Size = 0x400; / required amount of heap / that was in the original Altium project

2) Added properties . = ALIGN(4); in many places

mrguen commented 5 years ago

The proposed PeripheralPins.c discards TIM9, TIM10 and TIM11 but I see in variant.cpp

define TIMER_TONE TIM10

define TIMER_SERVO TIM11

So it might be necessary to reactivate TIM10_CH1 instead of TIM4_CH3 TIM11_CH1 instead of TIM4_CH3 ?
