When this bit is set and the boot pins are in the boot from main Flash memory configuration, the device boots from system memory, and the boot loader jumps to execute the user application programmed in Flash memory bank 2. This flexibility enables to tailor the boot process to suit different scenarios. So in case of Dual bank boot, if a bank contains stack pointer pointing outside SRAM1 it is considered by the bootloader as non valid, because the CCM-SRAM is not meant for being used as stack location. I think I can get away with a single boot bank, and defining two blocks of memory as two possible app locations. lhdg ndjgp xtn ahvs mojx rdxp ihmgw ewqklim kdhbzd cwvd rdyn bkl ovyj fyothja szb
