Avoiding segfaults in ld
I'm using the version of ld from Debian's armhf "Wheezy" distribution ("GNU ld (GNU Binutils for Debian) 2.22"), and occasionally I would experience segfaults in ld when linking. I was able to track down a workaround after building a debug version of ld, but I'm still not sure why it's segfaulting ...

Re: STM32F100: UART1 and I2C2 simultaneously
Answering my own reply. According to the reference manual, both devices share DMA channels 4 and 5. So the answer is: You don't use DMA.
So my options are either to use PIO or redesign the board.

STM32F100: UART1 and I2C2 simultaneously
Hi,
I'm trying to use both UARTD1 and I2C2 on an STM32F101 (similar to an STM32F100). I have my board defined, and I'm getting debug text out the serial port. The serial port will be the primary means of communication with this device.
I noticed that when I initialize I2C2 before UARTD1, I'm able ...
