------------------------------------------------------------------------------ README ------------------------------------------------------------------------------ This program demonstrates a little DMA MEM2MEM transfer. A string is send out to USART1 and afterwards copied by DMA to another memory location. To check if the transfer was successful we send the destination string also out to USART1. The terminal settings for the receiving device/PC are 115200 8n1. Building -------- $ make Running 'make' on the top-level libopenstm32 directory will automatically also build this example. Or you can build the library "manually" and then run 'make' in this directory. You may want to override the toolchain (e.g., arm-elf or arm-none-eabi): $ PREFIX=arm-none-eabi make For a more verbose build you can use $ make V=1 Flashing -------- You can flash the generated code using OpenOCD: $ make flash Or you can do the same manually via: $ openocd -f interface/jtagkey-tiny.cfg -f target/stm32.cfg $ telnet localhost 4444 > reset halt > flash write_image erase dma.hex > reset Replace the "jtagkey-tiny.cfg" with whatever JTAG device you are using, and/or replace "stm.cfg" with your respective config file.
