Hello, is there any Application note or guide for how to use ITCM and DTCM on STM32H7 Series?

Hello,

You can refer to the application note AN4891 "STM32H72x, STM32H73x, and single-core STM32H74x/75x
system architecture and performance" which describes the overall architecture of the H7 product, and how it's used as well as the performance results especially when executing code from ITCM and the data located in DTCM. See also X-CUBE-PERF-H7 (related to the said application note) how linker files are implemented.

Hope it helps.
