TPS65950/30/20: Continuous nRESWARM reset from OMAP at power up

Customer question:

Q: Why do we see continuous warmreset signal on TPS device during power up?

A: The warm reset on TPS is only an input. OMAP sends this warm reset signal if it fails to boot correctly. OMAP boots up based on the configuration selected by SYSBOOT pins. If this configuration does not match with the correct device (MMC, USB, UART) then the ROM code sends warm reset signal continuously.

Check SYSBOOT and the memory device.
