Re: F4 DFU bootloader

All my comments were an attempt to plead you to "Please leave Fredic and the STM Core alone, the USB is going to be great" * or at least it will be implemented without needing any USB magic reset code : ) * I wasn't talking about the libmaple core nor the generic core. I'm talking about the official...

Re: STM32F103ZE 64KB Memory Handle Error

Sometimes I wonder if people come in here and post questions just to troll us? The original poster doesn't seem to be showing us the code that he is really running. So for us to try and figure out what he is doing is just a waste of time. I can't really imagine trying to use an array of Strings the ...

Re: Hosting currently running slow

Speed has felt OK here (USA NC) . I've not felt like it was slow. I'm amazed anything in Houston would be up and running. Looking at their site it states their data center is on high ground safe for a 500 year flood. They must have got lucky. All the news reports here are talking about an 800 year f...

Re: Hi from Spain.

The Spark Core V1.0 seems to be a discontinued product using a discontinued wifi chip (CC3000). You are just asking to be frustrated. You aren't going to be able to get the WIFI part working if you can't figure out how to setup pins for stm32duino. A spark core v1.0 has zero support here and people ...

Re: STM32F103CBT6 BOOT Problem

Do you have a supported device like a bluepill? a Maple Mini? So other STM32F1 board that is known to work? If so you might try using that to verify that you can debug any board. If it does work, then because you have a custom board, I would start looking at your custom board connections and layout....

Re: STM32F103CBT6 BOOT Problem

I would spend some time in the debugger. I'm wondering about your LED being on the 32k xtal pins. I might move that. Not sure if the generic stm32f103c libmaple core tries to initialize it.

Re: STM32F103CBT6 BOOT Problem

Re: STM32F103CBT6 BOOT Problem

You should be using the ST-LINK upload method and no you don't need a bootloader. Selecting ST-Link as the upload method will load your code at 0x08000000 and would erase and replace the bootloader with whatever sketch you loaded.

Re: STM32F103CBT6 BOOT Problem

Do you know how to use arm-none-eabi-gdb .. maybe it is booting up but encountering some other error before it is able to run the loop() function

You might start up st-util and put a breakpoint on the reset routine and step through

Re: STM32F103CBT6 BOOT Problem

Why does your schematic show SWD connected to LMS 3v3?
-------- ... never mind ... that is not SWD but the target voltage.
