Hi,
In STM32H742xI/G datasheet (DS12110 Rev 8), the SRAM3 memory block is not specified in the "Table 7. Flash memory and SRAM memory mapping" but I can see the availability of the SRAM3 in the generated .map file.
Can someone please confirm, it is typo mistake in datasheet or really not available for STM32H742xI/G?
Thanks

Hello @palanib and welcome to the Community
After deep check, the datasheet is correct as the SRAM3 is not available in STM32H742x devices.
This is mentioned in the Table 2. STM32H742xI/G and STM32H743xI/G features and peripheral counts in the DS12110 Rev 10 and with more details in the AN4891 - Table 6:
Please provide more details on your project to better understand and reproduce your case:
Which project are you using?
which version of Cube package and tools used?
How did you generate your project and the map file?
