Hi I need to come up with a SLC NAND Flash Driver for STM32F405 which has a FSMC. My SLC NAND flash is ONFI 1.0 compliant (Micron MT29F). Any suggestion for a driver? Open source or commercial?I heared ST has one as well, but only available on reques...
Is there any way to find out if the code is executed on a H743 (single core) or a H745 (dual core) MCU at runtime?If I am not mistaken the DBGMCU_IDC (Identity code register) has the same value for both MCUs. Is there any other register which I could...
