This project is currently set up to build for just the STM32F070, including some specific configuration required for the F6 package of that chip that is unlikely to compile for other STM32 models.

To make this a little more accessible, it would be good to add support for building for the STM32F103, which is far more common on cheap development boards than the chip I've used.

I love the project and i'm very interested, dou you know if this is possible?

I bought a fresh STM32F103 (blue pill), as I initially bought a CKS32F103.

The problem now is, that the device will not be recognized as a USB device.

If I plug in my clone stm32, I will get the following

But flashing was successful of the new real STM32.

Do you have any idea? Unfortunately I'm no hardware programmer.
I'm thankful for any help :)

I get this output while executing make flash PROGRAMMER=stlink :

I'm new to st-link programming so any help is appreciated

Just wanted to let you know that I only got it working after I removed the "--no-floppy" option from the grub search command.
I also had to run dos2unix on all files before libopencm3 compiled properly. I got the error message: /usr/bin/env 'python\r' no such file or directory

Not really an issue, just wanted to share my experience. Amazing project by the way!

Hello, I have followed the instructions in this github and the hackaday post and while I am in linux I can mount the "drive" and see the FAT filesystem and files. However, when I drop to a grub shell and attempt to see the files I get this:

grub> ls (hd0)
Device hd0: No known filesystem detected - Sector size 512B - Total size 64KiB

I have another drive which is Arch Linux installation media and grub can identify that one as having a FAT partition just fine. Do you have any suggestions for how to debug this further?

Very happy with the project, not an issue, just i though it would be easier for some people if you add to the readme a couple things.

1. Switch is pull up detected on pin A6, so switch must be connected to A6 pin and GND.(As you published binaries , so they dont have to scroll through the code).
2. Depending on the mobo the usb devices are not detected on grub, change from "fast boot" to "normal boot", nativedisk could also be used but it can make your grub not to know how to boot into windows as there is some problem with chainloader.
3. The grub file to edit is, /boot/grub/grub.cfg(eventhough it is not recommended), as if you edit /etc/default/grub when you try to sudo update-grub it wont work. Also just paste it at the end of the file.(This can seem straight forward, but it isnt for newbies).

Would love to build one of these but I'm missing the components you're using. What are the models? Or names?

I recognize there's a similar issue that's already closed, but I have been unable to resolve the issue. I'll provide the same information.

• I'm using the stm32f103c8 "blue pill".
• I am using a st-link v2 cloner to flash. I was unable to flash using stlink, but i am able to successfully flash using st-flash. However, I cannot get ubuntu (let alone grub) to recognize the device in any way.
• Printing lsusb, does not list the device. Nor does blkid.
• The only things listed in the grub menu are my actual harddrives.
• I am able to reformat a flashdrive as FAT12 and both ubuntu and grub recognize it as such.
• grub version: grub-install (GRUB) 2.06-2ubuntu7
• search --fs-uuid 55AA-6922 returns device not found
• I am able to flash a blinking led program with success

My only thoughts are something has changed in the libopencm3 api making the usb initialization is not work?

Only warning i get when flashing is regarding nRST and i assume that is not related.

Let me know if anyone has any thoughts, thanks!

openocd-jlink.cfg currently needs to be modified if someone wants to program their device using an ST-Link.

Allow specifying the programmer to use as a parameter to make flash
