connecting stm32F4 in mios how to

[electrodancer]

Hello there

 

in the past ive always uploaded the hex with midi,...but i notice it does not work with the new stm32F4 core.

Also after uploading the bootloader with the stm software...it does not show up in the mios midi terminal.

 

whats have i done wrong?

 

cheers,

Vincent

and what is the "legacy usb driver" ??

 

(im running everything from a laptop and have no usb soundcard)

[Marxon]

So you successfully uploaded the MIOS32 bootloader app to your STM?

 

After flashing you have to use the STM Micro USB port instead the Mini USB port, maybe you missed that?

yess i have done that

 

and after this you a supposed to connect the seccond usb cable...when i do that notthing happens ...and in mios i can not select it

 

thank you for helping

 

cheers

electrodancer,

 

looks like a driver issue to me. try re-installing the correct version and then it should connect. if it doesnt, the problem is on your side...;-)

yes i was thinking that too....but already installed the driver...and nothing

 

maybe i have the wrong driver...could someone point me in the right direction ?

under "drivers" you can find the windows-drivers for mios32. make sure to pick the right one for you os. if it still doesnt work try uninstalling and re-installing...

i tried that driver (also uninstalled it and reinstald again) 

but keep geting the message instalation failed !

You dont need to install a driver.

The driver you downloaded is the GM5 driver and in the description is also written that the STM is not supported . You can use it as alternative to the legacy ("onboard") driver for other cores.

After you connect the Core Module, wait until your operating system has found the interface,

the driver will be installed automatically.

Look in your device manager if some new hardware (usb audio device) is detected. 

If nothing happens then there is something wrong.

Thanks for your help everybody

 

might have discovered the problem...the board ive got is a STM32F401C-DISCO

 

and needs to be STM32F407....(they look so much the same)

 

if anybody can think of a workaround ..so i can still use the board....il be eternally grateful to you

 

cheers

Welcome to the Club.  :rolleyes: 

Somehow i received a wrong wrong board too.

Same name, but another version.

 

[electrodancer]

im glad to hear im not the only one......they look so much alike !

 

is it possible to only change the processor ic ?....if this is possible i can order only the prosessor instead of a whole board

[Marxon]

Sorry there is no possibility.

It was discussed in past:

 

The STM32F401 is very limited, most major applications (such as MBNG, MBSEQ) wouldn't fit into the small flash memory.

 

However, before you throw it away, you could send it to me so that I can provide (and test) a MIOS32 variant for this chip for the case that somebody want's to use it for less complex applications like MIDIO128

 

Best Regards, Thorsten.

 

Where did you ordered your board?

Can you send a link?

hi marxon,

 

is the gm5 driver for the lpc-board, if its not needed for the stm32 ?

 

mOnO

[Marxon]

As said the STM is not supported but it is recommended for other cores running MIOS32 applications (including the LPC)

because it has a higher robustness of SysEx transfers and better a performance then the windows legacy driver.

The GM5 driver also gives multi client capabilities.

thanks for advising me.
