so just adjust clock speed i dont now what speed i used on nucleo 72.80 or 84mhz


#43

@valon_hoti_gmail_com The pin definitions in the files are way different than the STM32401, is that because it is the nucleo?

In the data sheet for the 411 it says SPI1 is PB3, PB4, and PB5 but in the definitions above you list it as PA5, PA6, and PA7.


#44

i created solution for nucleo stm32f411 and i belive nucleo stm32f401 should be the same
“but less ram and speed” - but i can not confirm because i have no nucleo 401 to check properly


#45

That was the first discrepancy I saw, there may be more.


#46

more info about pins regards nucleo 401


#47

The minimum files you need to change when making a new NETMF STM32F4xx port are these:

platform_selector.h // Freq, ram and flash sizes, xtal speed and pin mappings - in your case probably just Freq and ram.

STM32F4_BlConfig.cpp // Flash layout - should be ok for 401 vs 411

IO_Init.cpp // Turns on ports and sets default pins - prob ok for 401 vs 411

scatterfile_bootloader_gcc.xml // Flash and ram layouts
scatterfile_tinyclr_gcc.xml


#48

If I look at the datasheets then compare with the pinouts in these header files, the I2C and SPI pins are in different places. ST datasheets for the 401 and 411 match. But neither of those seem to match the header files


#49

@valon_hoti_gmail_com SPI1 and I2C don’t match either the 401 or 411 datasheets. I am confused…

#50

you do not need to see on datasheet so you can define by your needs

i prepared to meet my picture as presented here

https://github.com/valoni/netmf-interpreter4x/blob/master/NucleoSTM32F411Ret6/nucleo_f411re_arduino_netfm4310_400.png

and

#51

I need the pin outs to match the data sheets because I am substituting this on a board that was made for the G30


#52

and one thing how to calculate pins when you define it for exampe PAn
A=(16 * 0) +n
B=(16 * 1) +n
C=(16 * 2) +n
D=(16 * 3) +n

so based on calculation you get
PA1 = (16 * 0)+1 = 0+1 = 1
PB8 = (16 * 1)+8 = 16+8 = 24


#53

Can I delete the things I do not need like the LED part? Also I am unsure of some parts in bold below (hopefully I did the rest correct):

Did you mean scl pin is PD10 and SDA is PD11


#55

Little bit lost changing the Ram and Flash Layouts, especially in the two scatter files. All I know is to change the Ram Size line from 0x00020000 to 0x00018000…the Flash size is 512kb for both devices so that part doesn’t need to change. I am not sure about all the base address stuff and what else needs to be changed in these files besides that line.

Also I don’t really understand how 0x00080000 = 512 kb, doesn’t it equal 524288?


#56

524288/1024=512


#57

On the STM32F401 the SCL is pin 58 / PB6 and SDA is pin 59 / PB7. There is no PD10 or PD11

What is the 1024 from? Sorry I get mixed up by conversions


#58

524288 Bytes vs 512 KBytes


#59

Oh ya thank you, kilo makes me think 1000.


#60

You made wrong values
I give to you formula how to declare pins

A=0
B=16
C=32
D=48 so

PA0 mean 0+0=0
PA5 mean 0+5=5 (those values are not hex values)

PB7 mean 16+7=23 when you declare pins

And you seted value 58 is which mean 48+10 = D10


#61

I don’t understand what you mean. I am going straight from the ST datasheet:

Pin 58 = PB6 = SCL
Pin 59 = PB7 = SDA

It is the same in the GHI G30 datasheet as well:

My PCB is routed so that pins 58 and 59 are the I2C lines…I have to replicate that
