TPS536C7: TPS536C7 can no longer communicate with Fusion Design Online.

Hi Masafumi,

Can you confirm the controller has 3v3 measured on capacitors near the controller. Also, are you able to test running with fusion 7.9.8 so can see if it is update related? 

Thanks,  

Ryan

Hi Ryan

Thanks to  reply. 

１．I checked the supply voltage with a capacitor near the controller,
3.3V was correctly applied to the controller.

２．I used fusion design 7.9.8

Is it possible that only the communication block in TPS536C7  is broken?

Hi Masafumi,

Very unlikely the controller is damaged assuming normal conditions. Would be good to check the pull up's and confirm when the GUI is scanning for devices you see data on PMB_Data. Could also try a different GPIO to USB adapter. 

Thanks,

Hi Ryan

Sorry for the late reply.

>Would be good to check the pull up's and confirm when the GUI is scanning for devices you see data on PMB_Data.

I'll check it out.

Could you tell me how to do it?

What GPIOs can be used for that?

Best regards.

Hi Masafumi,

For the adapter I mean a different dongle,
