Hello everyone,
For a university Project we are using a STM32L4 MCU together with the IS61WV102416BL non multiplexed asynchronous SRAM. I followed the Application note which can be found at:
https://www.st.com/resource/en/application_note/dm00228015-using-stm32l476486-fsmc-peripheral-to-drive-external-memories--stmicroelectronics.pdf
Furthermore I adjusted the Linker file *.ld of my STM32 CubeIDE Project according to https://www.openstm32.org/forumthread2017 which works perfectly fine.
Now my Problem: When I try to write some data into my RAM I need to apply a Address Spacing of 8 like in:
uint8_t * dest = malloc(100 * sizeof(uint16_t));
for(int i = 0; i < 100; i++){
*(dest + i*8) = i;
}
If I do not do this I wont store the right values. Which makes it somehow inconsistent with the Internal RAM of the controller.
Now to my question, can I define somewhere how the spacing of the External RAM is done by the MCU. Because usually I would not need the 8 inside the *(dest + i*8) = i; expression. This causes also Problems my using standard functions as memcpy ect.
I hope I was able to explain the Problem somehow.
Best Regards!
