There is already a PR for dual core devices: #844, I'm also fixing the atomics support, which we will need for a multi-core message queue (plus MPU support to disable caching). |
No, I just wondered if I need to port the flash offset to CMake, too. |
Thanks for the pointer! This looks like a good start for me. |

Today I started playing around with my Arduino Portenta H7 board. It has a (yet unsupported) dual core STM32H7 and a bootloader. When trying to set the flash offset with
modm:platform:cortex-m:linkerscript.flash_offsetI noted that the dfu scripts always flash to 0x08000000.This is my proposal to support dfu with flash offsets. I have tested it with the Portenta H7 board using scons and make. CMake currently does not support dfu-util as a programming tool, right?
I have also verified that make and scons still work and dfu-util flashes to 0x08000000 when
modm:platform:cortex-m:linkerscript.flash_offsetis not specified.I'm looking forward to add support for the STM32H747 soon, at least for the Cortex M7 core.
