bq40z80EVM-020不能和新板卡通讯

bq40z80EVM-020和计算机能正常通讯，但不能和外置Cell-7新板卡通讯

The bq40z80evm-020 can communicate with the computer normally, but cannot communicate with the new external cell-7 board

问题详细描述：

Detailed description of the problem:

评估板bq40z80EVM-020，BMS020B能和计算机正常通讯。

The evaluation board bq40z80evm-020 and bms020b can communicate with the computer normally.

将J18的第1脚-第3脚短接，和J22的第1脚-第3脚短接，电池信息不能上传到计算机，测量SMBbus无波形

The battery information can't be uploaded to the computer by shorting the 1st-3rd pin of J18 and the 1st-3rd pin of J22. There is no waveform in smbbus measurement

Star Xu：

J18和J22是smbus通讯接的分流器.接法参考下面的说明.
If you're using test points TP10 and TP11, the shunts for J18 and J22 can be removed or J18 shunt position pin 2 to pin 3 and J22 shunt position pin 1 to pin 2 . If J19 is used for SMBus,shunts for J18 and J22 should be J18 shunt position pin 2 to pin 3 and J22 shunt position pin 1 to pin 2.

01

J18的Pin 2连Pin 3和J22的Pin 1-Pin 2，无通讯。

J18 shunt position pin 2 to pin 3 and J22 shunt position pin 1 to pin 2, No communication.

 

02

J18的Pin 1连Pin 3和J22的Pin 1-Pin 3，这样是可以正常通讯，但不稳定，从波上看有对有错。

J18 shunt position pin 1 to pin 3 and J22 shunt position pin 1 to pin 3,It can communicate normally, but it's not stable. From the wave, it's right or wrong.

 

03

现在的线路板是7节电池采用BQ40Z8RSMT，通过评估板对线路板进行配置，希望得到帮助，提供参考电路的连接关系

The current circuit board is 7 batteries with bq40z8rsmt. The circuit board is configured through the evaluation board. I hope to get help and provide the connection relationship of the reference circuit

Firmware exception

1
Yesterday's reply helped me to solve the problem of communication

2
It can communicate normally, because bq40z80rsmr of BP is a new IC, when programming, the prompt message is
Program Srec: Packet checksum mismatch.

3
You need to obtain the firmware corresponding to BQ40Z80RSMR in software bqStudio Version1.3.92 (XXX.srec ) What's the reason

4
Set to: jumper settings for J18 connect pins 1 and 3, and the jumper setting for J22 connect pins 1 and 3.
Otherwise, the DashBoard is gray
