Section for external SDRAM STM32F746 GCC
Hello !
First thank you your post helped me in the process.
I did it on an STM32f4x9I eval board.
You may have found your answer but I add my remarks if it can help others.
The problem for me is the way you declare youre picture :
- picture1480*272*3 ==> '*' cannot be used, use "x".
- "const char picture1[]" : why load const data into RAM ?, it stays in Flash. Anyway even if you want to do so your linker may detect const data and let it into flash.
You post have some things to clarify :
= ALIGN(8); why do you align on 8 bytes, 4 is sufficient.
attribute : the gcc linker use the attribute keyword.
