芯片型号: TLSR8258
SDK及版本: telink_zigbee_ble_concurrent_sdk-2.4.0.0
I make 2 firmwares.

- 1st firmware (FLASH_PROTECT_ENABLE is 1)
- 2nd firmware (FLASH_PROTECT_ENABLE is 0)

Test Sequence.
1) Run 1st firmware
2) Upgrade 2nd firmware via OTA
3) Run 2nd firmware
    -> In this case, Can I write flash(firmware area) ?

If the flash is protected before running firmware 2, the firmware area will still be locked when running firmware 2.
Because firmware 2 no longer supports protect (lock/unlock operation), firmware area cannot be written.
