Part Number: AM3359
Tool/software: Linux
Hi,
we upgraded a stable custom AM335x design from TPS65217D PMIC to TPS65218D0.
The boards boots fine ti linux kernel 4.14.79 from processor sdk. Rebooting via "reboot" is fine.
But shutdown via "halt -p" does not shutdown but reboot the board. I found that this - or something similiar - was an issue with prior
silicon of the PMIC. But we have the latest - chipid is 5.
Design is based on http://www.ti.com/lit/ug/slvuaa9a/slvuaa9a.pdf.
I am not sure if this hardware of software releated. I took the TPS65218 devicetree node from am437x-sk-evm.dts.
DCDC4 is used for all 3.3V peripherals on our board. Our initial TPS65217 based design was always fine.
Regards,
Matthias
