custom project based on STM32H745I-DISCO but external memory and flash necessary for T-GFX and external loader is not available in the market.

Would you please help pointing chips with exact pinout and specs if any as replacement for:

QSPI: MT25QL512ABB8ESF-0SIT

SDRAM: MT48LC4M32B2B5-6A IT_L TR

hello

for SDRAM just different revision

[ksale.1]

Thank you @Vangelis Fortounas​ ,The only obvious difference as per the Datasheet is the memory size:

4 Meg x 32 (1 Meg x 32 x 4 banks), proposed replacement is 2 Meg x 32 (512K x 32 x 4 banks).

My main concern is the External Loader "MT25TL01G_STM32H750B-DISCO, 0x90000000, NOR_FLASH, MT25TL01G_STM32H750B-DISCO.stldr" provided by IDE, will it work with MT48LC2M32B2B5-6A IT:J TR?

The External Loader is uninvolved with the SDRAM
