On STM32F7 DMA triggered by APB1 timers fails

I have STM32F7 Disco board with STM32F723IEK MCU. Trying to trigger a DMA request from a timer causes a DMA error, but only for timers from the APB1 group (TIM2 to TIM7 and others), that are connected to DMA1. Doing the same with TIM1 and TIM8,…

Producing two outputs from a Linker script

There is a Quad-SPI NOR device on the STM32F746G-Discovery Board that I would like to use to store read only data. So the ideal would be that the linker file produces an ELF file for the F746G flash and a hex file to program the NOR. Then I could…
