Hi,
I am following the OTP step as the below list. But sometimes will fail, the OTP_STATUS bit is "0". Would you help it? Thanks!
1. Make sure register 0x16 is 0x1AH.
2. Make sure the DRV2605 VDD is 4.2V.
3. Set the OTP_PROGRAM bit(0x1E bit0) to “1”.
4. Read OTP_STATUS bit(0x1E bit2), it should be “1”.
5. Remove Vbat or set DEV_RESET bit(0x01 bit7) to “1”.
For step2, I read 0x21 for the VDD, can I trust it?
Between step3 and step4, how long should we wait?
I guess we do not need to wait any time.
And we wait about 90 seconds, OTP_STATUS do not change to 1.
