Yes, STM32 flash is a bit of a "gotcha" - that is not the only problem with it - normally you can read one page while writing/erasing another, but in STM32 the entire flash bus stalls, so no no code in flash runs - stalling execution for significant periods (tens of milliseconds). – Clifford. WitrynaSome blocks (1 block = 64 pages) are declared as bad blocks. During testing, bad blocks are marked in spare areas of the first 2 pages of NAND flash. User should read bad block marks and avoid using them. Due to repetitive use of NAND flash, additional bad blocks may be created and user should also handle new bad blocks.
