  told me to report on this forum any corrections needed in reference docs and code.

These corrections apply to the latest published reference manuals for STM32F3xx:

RM0316: STM32F302xx, STM32F303xx and STM32F313xx advanced ARM-based 32-bit MCUs DM00043574.pdf

DocID 022558 Rev 2.0

RM0313: STM32F37xx and STM32F38xx advanced ARM-based 32-bit MCUs DM00041563.pdf

DocID 022448 Rev 1.0

1) Table 24. Programmable data width & endian behavior; Source port width=32, Destination port width=16: Transfer operations should read ''WRITE BxBy[15:0]'' not ''...[7:0]''

2) USART Section 5.4 Baud rate generation; Example 1 In case of oversampling by 8: calculation should read ''0x3 >> 1'' not ''... << 1''.

Hello Gary,

Will check for RM0313 but I don't understand how did you get new reset values that you suggest for RM0316.

Could you please explain?

Thanks & Regards,

I loaded the following for firmwareusing the STM32 ST-LINK Utility:

void __attribute__((noreturn)) Reset_Handler() 
{ 
// Need to enable the port clocks 
RCC->AHBENR |= RCC_AHBENR_GPIOAEN|...|RCC_AHBENR_GPIOEEN; 
for (;;) { } 
} 

Then I examined the register values in the Device Memory window. -Gary

Hello Gary,

You are right.

Thanks again for your contribution. Your feedbacks will be taken into account in next reference manuals releases.
