tps65950: "8 seconds PWRON pression" reset doesn't work

Other Parts Discussed in Thread: TPS65950, OMAP3530

Hi

on my omap3530 + tps65950 project the 8 sec reset doesn't work, the tps doesn't send the nRESWARM signal to the OMAP.

Any suggestions?

Many thanks.

Andrea

 

  • Hi Andrea,

    Warmreset and the 8-se reset ae completely different and not related. The 8-sec reset is not set at power up. You will have to enable this in software by setting STOPON_PWRON bit to '1'.

    Warmreset is an input on PMIC. If you want to use this then OMAP will have to generate this reset. OMAP sys_warmreset should be tied to nWarmreset pin on PMIC. I dont know your schematic so I am not aware how you have this connection on your side.

    Hope this helps.

     

    Regards,

    Gandhar.
