BQ34Z100-G1在烧写Golden Image之后无法用I2C通讯

Other Parts Discussed in Thread: BQSTUDIO

我们正在使用自己设计的板,其中BQ34Z100-G1用来测量电池的剩余容量。这块板已经连续运行了好几个月并且数次烧写过Golden Image。但是昨天烧写Golden Image之后bqStudio显示成功,之后就无法用I2C进行通讯。

我尝试了如下步骤但是都无法恢复通讯:

  • 重新烧写。
  • 点击Execute FW
  • 断开电量计和电池的连接并再次连接,之后分别尝试了上面两个步骤,还是无法通讯。
  • 手动输入I2C命令:I2C Command 0x00: Data block 0x000F I2C Command 0x64: Data block 0x000F I2C Command 0x65: Data block 0x0000

REG25的输出为稳定的2.5V,I2C信号无ACK

bqStudio 版本(1.3.54) EV2300 版本 3.1r.

还望得到各位的帮助,谢谢!
