Hi Max

it may be recommended to check power supply VDDHIGH_IN, VDDHIGH_CAP, it powers

MIPI block NVCC_MIPI, and move it first, if possible, along with

VDDSNVS in power-up sequence. In general extending POR also may help.

Best regards

Hi Max

1 check power supply VDDHIGH_IN, VDDHIGH_CAP voltage ripples

2. extend POR up to 1 sec.

3 change power-up sequence so VDDHIGH was 1 step with VSNVS

Best regards
