Part Number: TPS65987EVM
Hi,
It comes to some problems when we used the TPS65987 EVM.
Use a 24V adapter to supply the TPS65987EVM, and the EVM was connected with computer by I2C.
1) The configuration interface was as follows. The numer of PDOs was 1.
2) Then do "Import settings from device" ,while there were no changes in the configuration interface.
3) Do "debug", the interface was as follows. The number of PDOs bacame 4. So did it means that the importing settings was effective? Or something else?
4) In this mode, connect a PAD and EVM by TYPE-C cable, the PAD could be charged by 9V. While a few moments later, the interface became as follows. The PDOs became 7. There were something wrong in "Device 1, port 1".
5) Exit "Debug" mode, the interface was the same as the picture 1.
6) However, if we did "Export settings to device RAM" in step 2, which PDOs was 1 and the voltage was 5V. Once we connected the PAD and EVM, the charge power was 9V. We suspected that the configuration file wasn't downloaded to the EVM.
Looking forward to your reply, thank you.
