Part Number:BQ27Z561EVM-011
Hi,
I am currently working on BQ27Z561EVM with BQ27GDK000EVM. I followed the user manual to connect all the components as shown below:
It works fine until this morning. Yesterday evening, I started an experiment which in theory should finish at 2:30 pm today. However, when I came to check the experiment at around 1 pm today. I found in bqStudio, the icon of battery gauge was gray which means the battery gauge is not detected. Then I checked the instruments, the battery gauge and the GDK. It seems that there is no problem on GDK. But on the battery gauge I found something strange that the PWR LED is on as shown in following picture, which means the gauge is powered on. Normally, that LED should not be on when the battery gauge is connected to GDK. Then I test the battery gauge separately by connecting it directly to my PC. My pc is able to recognise there is EV2400 connected, However, bqStudio still cannot detect BQ27Z561EVM. I tried to find where the problem is and make it work for several hours. While, till now, it still does not work.
Could you give any idea or advise to find the problem? If you need any further information, just tell me.
Just one more sentence that system works well for almost one month. During that period, the system was kept in a safe place and all the connections were fixed.
Kindly regards,
Wenlong
