What is the endianess of STM32F407? Datasheet conflicts with real test.

[yanhc]

I checked the data sheet of STM32F407 and it says it is little endian.

However, when I test in a real device in MDK, it shows that it is big endian. I assign an int "testttt" as 0x12345678. Then, in memory window, it shows as 0x12345678 which is big endian.

Is there anything I missed?

Thanks for your help in advance.

I think you missed the point that the processor doesn't perceive the numbers as being backward, you write 0x12345678, the processor and debugger see it as a 32-bit word 0x12345678.

Want to see it in byte order? Then select the debugger memory view to show BYTES rather than WORDS.​

OK, I got it. Thanks very much.​

Just find that MDK memory view can display such many options: char, int, short, long, even float and double. Cool!!!
