    Philippe MAIRE
    Hi, Can I chain PMIC & OMAP jtag connexions ? I am afraid that when in test mode, the PMIC could stop providing power, then the OMAP turns off and breaks the chain... Have any of you tried this successfully ?

    Hi! Gandhar: Thanks for your answer, but I find TI's application report (TPS65910 User Guide For AM3517/AM3505 Processor), "PWRHOLD" is connected to VDD2 or VIO. But in cranboard;s schematic, it connected to VRTC. What difference from them? (because VIO, VDD2, VRTC has different...

    Gil Zhaiek
    Thanks Tony! Gandhar, we did look at the signals and they look fine. Clean and in great shape. What I am thinking is that looking at the tps65950 code in the driver - drivers/mfs/twl-core.c - there are mutex locks before each of the i2c_transfer. These mutex locks are only per driver and not per...

    Philippe MAIRE
    Hi, On my OMAP board, the 32,768 Hz clock is a square clock provided by an external RTC. The duty cycle of the clock is at about 40%, and I just noticed there is a requirement of 45/55% in the SWCS037E datasheet. The OMAP on its side does not require a particular duty cycle on this clock. ...

    Hi, we are planning a design with a AM3715 and the TPS65920/30. The design should provide the possibility to realize a version with AM3715CUS (800MHz) and AM3715CUS100 (1GHz). I have found a hint that the TPS65920/30 is not suitable for OPP1G (operation point 1GHz) - i am a little bit confused...

    Hi, Is there any reference driver available for TPS65951 on Linux? We are considering using this PMIC to replace TPS65950 on DM37x EVM. I saw there are quite a bit of registers difference btw TPS65950 vs 65851. Are there any sample driver for TPS65951? Thanks for any info.

    Jiansheng Liu
    Gandhar, I do have problem with this PWRHOLD connection and really hope you can help to confirm it: as my understanding PWRHOLD is used to maintain Power ON status after all of power rails are up, and it should also return to zero once power -off procedure is completed. According to this it is make...

  • Forum Post: Re: TPS65910's PWR_HOLD setting

    Jiansheng Liu
    If we pull PWRHOLD to NRESPWON, it means that any of reset event from AM3715 will trigger a PMIC power off sequence, that is not what we looking for. I will find out the root cause of that VIO can't return to zero, whis was caused by a off board signal, and has nothing to do with the PMIC. So I will...

However when we implement software controlled power off (by using DEVICE_OFF bit), it was found that the...
