BQ79616-Q1: FAULT_OTP:CUST_CRC bit is set

Part Number: BQ79616-Q1

I believe this issue is caused by change the GPIO_CONFIG register. I changed GPIO_CONFIG registers to set them as ADC input. How do I fix this issue ?

    Hi Abhijith,

    The reset value for both CUST_CRC and CUST_CRC_RSLT are 0x31F3, if you're configuring any of the OTP shadow registers (0x00 - 0x37), the CUST_CRC_RSLT will compute the CRC value and you'll have to update in the CUST_CRC as well. If they're not matched the fault will flag.

    I would suggest that you check if you've change any of the OTP shadow registers as the first step. 

    Best,

    Andria
