Posted on September 06, 2016 at 21:37Is it possible to read the device type in user code?  I would like to write some code that uses the crypto acceleration hardware if it is running on an STM32F415 and falls back to software implementations if it i...

Posted on August 05, 2016 at 02:33I have an STM32F416 embedded in a USB device that I want to act like a keyboard device when plugged in to a PC.  I'm using the STM32Cube USB device library and the UM1734 documentation.  In the documentation it says...

Posted on June 28, 2016 at 08:29I initiated a change from RDP level 1 to RDP level 0, which in turn initiated a full flash erase.  But before that process completed I pull the power on the chip.  Now dfu-util refuses to load new code, saying:dfu-uti...

Posted on June 15, 2016 at 19:16I just discovered the hard way that if you initiate a full flash erase cycle (in my case, by going from RDP level 1 to level 0) and reset the chip before that process is complete then the chip is essentially (AFAICT) ...

Posted on June 13, 2016 at 23:54I am using an STM32F415 as part of a USB dongle that generates and stores cryptographic keys.  For the development version of the dongle I want to be able to switch back and forth between RDP levels 0 and 1, which I c...
