BL702 Internal flash sector size

makc

Hello,

What is BL702 internal flash minimum allowed erase sector size? Is it 4K, 32K or 64K?
According to the configuration files in bl_mcu_sdk/tools/bflb_flash_tool/utils/flash/bl702 all supported flash memories support 4K sector erase command (sector_erase_cmd = 0x20).
But is there any guarantee that there will be no other flash memories with larger minimum erase unit size?
