Part Number: BQ27220EVM-744
Other Parts Discussed in Thread: BQ27220, EV2400

我们从 BQ studio更改了电池容量、电池电压,然后生成了一个烧录文件,连接好了BQ27220的EVM、电池、EV2400,通过Launch Smartflash Software能正常的连接上BQ27220的EVM,但是无法完成烧录。

以下是我们的操作步骤说明:

  1. 从 BQ studio更改了电池容量、电池电压,然后生成了一个烧录文件0220_0.ot.fs文件
  2. 连接好了BQ27220的EVM、电池、EV2400
  3. 打开Launch Smartflash Software,打开并选择0220_0.ot.fs烧录文件。
  4. 点击烧录后,弹出提示连接7.4V的电源的对话框。
  5. 手动接入7.4V电源后,依然无法完成烧录。
