I am currently trying to do a Battery Learning cycle using bq27520 EVM. I have successfully passed it before and now I am doing it on a different battery. But something has gone wrong during the Learning cycle and the readings of Fuel Gauge is always "0" in the battery meter shown below. But the measurement readings like Battery Voltage and Battery Current are still correct.
To rectify this, I tried refreshing the firmware but I am getting the following error: Failed Read Data with (Decimal Code) Error 772
I checked the Fuel Gauge is unsealed and I am unable to figure out why am I not able to reset the firmware to the default .senc file downloaded from the website.
Can someone help me out in configuring the EVM to default state so that I can start the learning cycle again?
