Hi,
I have one question regarding ABB (Adaptive Body Biasing) of AM5728.
Now my customer uses TPS659037 as a PMIC with AM5728.
And VDD_DSPEVE, VDD_GPU and VDD_IVAHD are connected to same SMPS output(SMPS45).
For AVS, customer uses the same setting for three VDD(DSPEVE, GPU, IVAHD). It is for VDD_GPU.
Customer does not use DSP and IVAHD.
And then, now customer does not set ABB for these three vdd. Now only VDD_MPU is set for ABB.
However, according to the data manual of AM572x, AVS and ABB are required.
How should customer set the ABB for VDD_DSPEVE, VDD_GPU and VDD_IVAHD?
Please advise me .
I appreciate your quick reply.
Best regards,
Michi
