Re: Hi every one KHODIDAS from INDIA

Arduino_STM32 only has limited support for the F4 series ( this is documented in many places)

You should try using the official STM core, and post an issue to

Re: Suggest having BluePill pins defined for all Arduino pins

One slightly confusing thing on that diagram is that the Alt pin for SPI1 are show without any indication that they are only used if you call the appropriate AFRemap function.

Re: PR to add optimisation menu (to all boards individually)

No worries...


Re:LTO

I have not noticed any problems in gcc 4.x, except LTO does not always result in smaller or faster code.

Also, in LibMaple I have noticed enabling LTO shows some warnings during compilation, but they dont seem to effect the operation of the code.

Re: MapleMini : Standalone Bootloading and USB/Serial Usage

There is a special branch of the repo for some Ham radio guys where DTR is not needed, but is quite out of date, so if you can find a terminal that can set DTR its the best bet

Re: MapleMini : Standalone Bootloading and USB/Serial Usage

USB Serial works with most terminal programs but the terminal needs to set DTR (some don't)

Re: invalid dfuse address for Black magic probe

Umm

You mean you recompiled and DFU no longer works ?

If you had a really old version of BMP then upgraded it, they totally changed the way the DFU works. But AFIK they changed it ages ago (perhaps a year ago)

I think you'll need Gareth @ Blacksphere to help you with this.

Re: invalid dfuse address for Black magic probe

DFU has nothing to do with the ARM toolchain

Its to do with the version of DFU and Windows driver you have installed and associated with the device (BMP DFU USB device)

Re: short on VBAT?

I looked on the original MM schematic and VBat is only supposed to be connected to pin 1 on the MCU

Looking at a MM clone, it also looks like VBat is just connected to pin 1

Of course your MM clone may be different

Re: Hello from Norway

Ok..

I cant keep uo with the number of STM32 boards that are available. ;-)
I suspect there are hundreds of different types available, all different shapes and sizes.

Re: MapleMini : Standalone Bootloading and USB/Serial Usage

The bat files take multiple paramaters The easiest way to figure out what is passed to them, is to comment out the line at the top that disables echo Then add some echo statements to sprit out the args that are passed. then run the ide, make sure verbose is turned on in the preferences, do an upload...
