Hi All,
We are using AM5718 processor with PMICTPS6590379ZWSR (OTP: 0X97). We first observed the volatage rail VDDA_PCIE was a short. But since other voltages were proper the DSP was booting up. We continued the operation without rectifying the issue. After 2 days another rails(VDDA_USB, VDDASATA) started showing short. but the operation was continued as our application didnt require SATA and USB. But, now the 3.3 (VDDSHVx) volt is also showing a short. The short is on DSP side as we isolated the PMIC and DSP, Also, the powergood of PMIC is asserted.
What is the reason of such erratic behaviour? Please give us a probable reason and solution if any.
Thanks,
Rajneesh
