Hello!I am trying to use DTCMRAM on my stm32h743zi micro.When i use an array located from 0x20001760 to 0x200017d4 there are some positions that do not update, it stays in 0 or "inf" value, but when i use other array located in different location, it...

Hi @TDK2 . I show you in the next image, there are a few values in 0 and then in "inf" using these directions. But if i use other array with other directions, everything works perfectly. I am lost in this problem. Thank you so much
