Dear all,


I'm using STM32H743ZI (nucleo-H743ZI board)

This µc have 1Mb of SRAM (512 Kbytes of user sram ?)


When i declare array of 100k uint16

I have this error message :

"section `.bss' will not fit in region `DTCMRAM'"

region `DTCMRAM' overflowed by 79544 bytes


How I can place this array in User SRAM ? Not in DTCMRAM ?


Thanks in advance
