@Kocsonya: is everything you said about I2C module, valid for QSPI module as well ? 6 QSPI pins are located across 2 GPIOs PB PF (PF is also used for ADC). So I...

STM32H747 GPIO access by two cores

New thread started 2 years ago
HiI use dual-core STM32H747 for math processing and periodic output via QuadSPI on M7 processor, and the rest of hardware control with I2C on M4. Apparently I reserved...
and solution was: in Keil Application/MDK-ARM folder (which had two files), delete this M4 filestartup_stm32h747xx_CM4.sand keep this M7 filestartup_stm32h747xx_CM7.sThey...
I switched off .sct files usage, and set --first for CM7 and --last for CM4. Linker thrown hundred errors like this:new from scratch Eval_CM7\new from scratch Eval_CM7.axf:...
it's all here: https://developer.arm.com/docs/100070/0612/scatter-loading-featuresa lot of reading, and no any simple working example for the DualCore MCU...L6235E: More...
Thanks for the support. Yes, I tried example codes: Dual-Core Blinky and FPU Fractals - the only two examples available today for STM32H747. They both are non-CubeMX....
Thank you for support. I tried few very simple projects in CubeMX on DualCore STM32H747 - the same problem happens in Keil: conflict in .sct file. This file is generated...
In CubeMX my project has the option "Dual Core Boot Mode" = "Both CPUs booting at once". After generating code, I compile it in Keil. Linker complains:"Build target...
