Hi All,
We have accommodated RZN1D series-based MPU R9A06G032NGBG#AC1 in our design. We are at the pre-production phase and this issue caught our attention, need your extreme support to close this issue.
Issue description:
The system is not resetting and hanging in the following conditions. 1. While pressing reset button.
2. Randomly when the application runs.
Schematics snapshots
Reset (green) waveform at normal condition
Reset (green) waveform while getting stuck/ Hang
We have observed that the reset lines are properly functional in all conditions. Please let us know if there is any known issues or work arounds for the same or else we need a technical discussion with your SMEs to resolve the issue
Hi Sreehari,Our team is investigating your issue and soon you will get a response.Kind Regards.
Dear Team
We have observed that the PMIC is disabling and 1V15 and 1V5 regulators randomly. We are using the same binary from Renesas EVK (RZ/N1D-DB). Please share the code with us so that we can optimize the same.
Hi Sreehari,
> Please share the code with us so that we can optimize the same.
Please check the RZN1 Solutioin Kit Package folder YCONNECT-IT-RZN_V1.4.x\Documents\RZN.Boards\RZN1D-DB. The zip file RZ_N1D_DB_Lattice_PMU.V600.zip holds the actual PMU POWR605 PMIC data base from Lattice.
This file is listed in the related top level document Readme.Release.V14x.pdf inside the Solution Kit package. Or is something missing in this Lattice PMU Programming Data Base?
Best regards, Andreas
