Hello I want support for STSPIN32G4 EMI Issue
I took tests for Farfield EMI Report at STSPIN32G4 Standby condition
Report shows QP are over than Limit at 190.547MHz, 253.803MHz
and I also get similar result by using Near-field prove(Proved Noise Peaks : 185.91, 123.94, 247.88, 309.84MHz) this result are same at evspin32g4-dual(also Flash Erase conditions results)
I guess 62 MHz harmonic noise occurs between STM32G431 and STSPIN32G4 Internal Control logic Because I observe noise when Voltage input to VM and REGIN for the (in 3.3V externally supplied circuit)
I want to know how could i solve this problem(Resolving EMI noise)
