ESP32-C3 无法关闭加密。

[physton]

买了3片"新"的ESP32-C3FH4，正常烧录成功，会报错：

Code: Select all

esptool.py v4.5.1
Serial port /dev/cu.usbserial-1140
Connecting....
Chip is ESP32-C3 (revision v0.3)
Features: WiFi, BLE
Crystal is 40MHz
MAC: 10:91:a8:e3:13:30
Uploading stub...

Stub running...
Configuring flash size...

A fatal error occurred: WARNING: Detected flash encryption enabled and download manual encrypt disabled.
Flashing plaintext binary may brick your device! Use --force to override the warning

通过添加 --force 参数后可以烧录进去，芯片日志一直是 invalid header: 0x97df56ec。

查阅官方问题，发现可以通过以下命令实现关闭加密：

Code: Select all

espefuse --port /dev/cu.usbserial-1140 burn_efuse SPI_BOOT_CRYPT_CNT

但是执行后，还是有报错：

Code: Select all

espefuse.py v4.7.0
Connecting...
Detecting chip type... ESP32-C3

=== Run "burn_efuse" command ===
The efuses to burn:
  from BLOCK0
     - SPI_BOOT_CRYPT_CNT

Burning efuses:

    - 'SPI_BOOT_CRYPT_CNT' (Enables flash encryption when 1 or 3 bits are set and disables otherwise) 0b001 -> 0b011

A fatal error occurred: 	SPI_BOOT_CRYPT_CNT is write-protected. Burn is not possible.

也试过其他的命令，但都是提示参数无效，只有 burn_efuse SPI_BOOT_CRYPT_CNT 能够运行，但是会出现上诉错误。

Code: Select all

espefuse --port /dev/cu.usbserial-1140 burn_efuse FLASH_CRYPT_CNT
espefuse --port /dev/cu.usbserial-1140 set_flash_encryption_disabled

也尝试强制清理过flash，但都无效，芯片一直是加密状态。
所有命令均在下载模式中执行的：

Code: Select all

rst:0x1 (POWERON),boot:0x7 (DOWNLOAD(USB/UART0/1))

实在找不到解决办法了，请大佬解答帮忙，感谢！
