We have a LP8764-Q1 based design. In working revision of this design, we had REG_CRC_EN = 0.
We used an USB to I2C dongle (aardvark) to re program the device.
In the updated design file, we have the following setting
REG_CRC_EN =1
RECOV_CNT_THR = 0
but the CRC value was not stored in the expected location. The unit was power cycled.
Now the PMIC device is not coming up (probably because the CRC does not match) as well as the device keep doing retry as the RECOV_CNT_THR = 0.
We are not able to re program this device.
Is there any way we can re program the device ? Will we be able to re program the device if we use the PMIC EVM board and the PMIC Scalable GUI interface ?
We have this wrongly part in multiple boards and we are blocked.
Please let us know if there is anyway we can recover this part without having to replace the part with a new part.
Please treat this as an urgent request
Thanks
