It was found that the range of the VDD_SNVS_CAP voltage is quite large and the tester was configured to accept 1.0V..1.2V.Nevertheless there are still some boards that are failing due to this voltage being either lower or higher, meaning that the range either needs to be extended or ...
After power on, VDD_ARM_CAP, VDD_SOC_CAP voltage do not rise.After turning on the power,CPU Side - VDD_ARM_CAP: 0.06V - VDD_SOC_CAP: 0.139V - PCIE_VP_CAP: 0.07V - VDD_HIGH_CAP: 2.5V - VDD_SNVS_CAP: 2.5 V - NVCC_PLL: 1.12VPMIC Side - SW1A: 1.376V - SW1B: 1.370V...
