Achieving "Extra Quality" with the ST2524F is less about the silicon itself and more about the software discipline. By implementing Read-Back Verification, Power-Loss Recovery, and Active Status Register Monitoring, you transform a standard commodity flash chip into a reliable storage medium suitable for industrial and automotive environments.
Before upgrading, you must know your baseline. Follow these steps to check your firmware:
If you see only a generic number (e.g., v1.0), you likely have basic firmware. If the version includes terms like "HQ", "Pro", or "XT", you may already have a quality build—but not necessarily "extra quality." st244f firmware extra quality
# nvme set-feature /dev/nvme0 --feature-id=0xE7 --value=0x80000000 --save
To verify:
nvme get-log /dev/nvme0 --log-id=0xC1 --len=512 | grep -i "quality"
Expected output: Extra Quality : ACTIVE

Most ST244F boards have a BOOT0 pin or a hidden button. Short BOOT0 to 3.3V while resetting. Your PC should detect an STM32 device in DFU mode. Achieving "Extra Quality" with the ST2524F is less
After flashing, read back the memory:
STM32_Programmer_CLI -c port=USB1 -r 0x08000000 0x20000 readback.bin
Then compare checksums. If they match, proceed. Before upgrading, you must know your baseline
