Hello I have a question about programming brand new STM32F1xx chips, as it relates to the Sparkcore as a development platform and subsequent, custom board production. Setting the Scene So, let’s say I have made my own PCB, which contains a brand new, never-before-programmed STM32F103 chip, like t…

Basically, you need a ST-link V2 programmer to program the brand new chip. Once you have some bootloader of that sort, you will be able to use DFU to do the job. With that said, the bootloader can only be changed using the programmer.

[image] kennethlimcp: Basically, you need a ST-link V2 programmer to program the brand new chip. Hey @kennethlimcp . Thanks for the reply, but I guess I wasn't clear about what I was asking. What software is required? Does the ST-Link/V2 programmer come with it? Does it run on OS X? Is it GU…

I don’t own one and dont have a mac too. haha! Looks like it might be a command line thingy on Mac and you have to build it or something. @zachary and @satishgn will know best :wink: Why wouldn’t you consider the cores since the bootloader, manufacturing etc are all done for you? :smiley:

ST-Link comes with a utility program that only runs under Windows (works fine with 8.1) and you can use that to write a .bin file to the chip. I’ve used to re-ffash the boot loader on the Spark Core. You can also use ST-Link with CO Ide (a free development environment from CoCox that has great sup…

[image] kennethlimcp: Why wouldn't you consider the cores since the bootloader, manufacturing etc are all done for you? Because it's too expensive and bulky for bulk-produced custom devices based on the Sparkcore. If you read the spark.io home page, near the bottom you'll read the following …

@pra – thanks for that. What about chip configuration? With Atmel AVR and Microchip PIC chips that I am more familiar with, there are configuration registers that need setting, to set what type of oscillator, what speed and for locking Flash memory for bootloader sections and all that sort of thing…

Yep the ST-Link Utility coupled with the Spark JTAG programmer shield is what you need. [image] STSW-LINK004 - STMicroelectronics STSW-LINK004 - STM32 ST-LINK utility (replaced by STM32CubeProgrammer), STSW-LINK004, STMicroelectronics Just load that bootloade…

Well chip configuration is required for all ARM microprocessors, regardless of vendor. ARM mandates all vendors provide CMSIS for their product that standardizes a lot of this. Most vendors, including ST Micro, provide a library of low level routines that will perform configuration and provide dri…

[image] pra: Most vendors, including ST Micro, provide a library of low level routines that will perform configuration and provide drivers for most stuff. Thanks. Sounds though like you are talking about configuration done in executing code, during boot-up. This is not what I was referring t…

@BDub … thanks. Somehow, I completely missed your post, earlier. I’m about to go read the guide you posted. In the meantime, I have obtained an ST-Link/V2 and got it running with OpenOCD. I tried ST-Util first, which I found by Googling something or other. It worked well for flashing but was a de…

I replied to @gruvin in another more focused thread, but I wanted to make sure the link was available from here too:
