I found that I have to change the define "__PACKED" to "__packed" in "cmsis_armcc.h"; otherwise, the following code in "stm32h7xx_II_usb.c" will crash on the second call to this function, if the "len" in the first call is 7 ( or might be other none 3...

The current STM32CubeMX package cannot generate proper code to initialize the VREFBUF in STM32H743 MCU. Modifications to HAL_MspInit() in stm32h7xx_hal_msp.c can fix this: Add "__HAL_RCC_VREF_CLK_ENABLE();" to user code section 0.In user code sectio...

Thanks.It is a STM32H743IIT6. ( - VQ911426 AA157 - TWN AK 936 - V e3)Looks like the silicon is Revision V, manufactured in 36s week of 2019.The latest RM0433 still says the pins can be used as GPIO if the DAC is configured to connect to internal par...

Is it OK to use "PACKED" other than "packed" in "cmsis_armcc.h"

Can I use PA4/PA5 for SPI1 while I also use DAC module? What I found is that the SCK an NSS do not function as soon as I enable the DAC channel 1 and channel 2, even I configure the channels as "connected to on chip peripherals with buffer disabled"

VREFBUF not working on STM32H743?
