Bug in STM32CubeIDE, Version: 1.10.1, Build: 12716_20220707_0928 (UTC), regarding IRQ on DMA transfers with STM32F401

[SLink.1]

I have a small project which should generate an interrupt whenever a DMA transfer has completed. If I build the code for an STM32F411 then it works exactly as expected. If I build that same code for an STM32F401, which is within the same family as the 32F411, then the project is not built correctly. The DMA transfer still happens, but there is no interrupt upon transfer completion.

The problem is in the vector table.

As you can see, it goes directly from ".word   EXTI4_IRQHandler" directly to ".word   ADC_IRQHandler". All those reserved words in-between should be for the DMA IRQ handlers.

As a quick workaround, you may generate the basic project for F401CCxx (which generates the correct startup), then copy the startup module from it to your project. Or, alternatively, (self-promotion warning) you may use my startup generator to create the correct C startup: https://github.com/gbm-ii/Cortex-M_C_startup_gen
