Hello everyone, I am trying to use STM32H725 processor with NAND FLASH 25N01GV. The installation seems successful. But sector erase always fails with the same error Status Register(0xC0) = 0x04 (EFAIL - Erase Failure )1. JEDEC ID read successful.W25X...

Thank you for your answer. I know that it is necessary to send an 8-bit dummy after the SECTOR ERASE command. You can see this if you look at the end of the tables. I think the source of the problem I am experiencing is different.3. Sector Erase:a. W...
