Sigh, nope, Angstrom 3.8 (disabled OTG detection) didn't fix the issue either. As of late, the BBB actually powers down completely (power LED is off). And pressing the power button, reset button, even BOOT button does nothing. Hell, even unplugging and plugging back in the power doesn't do anyt

I can confirm that the pulsing detected by PMIC on USB_DC signal is the probing from USB-OTG. After I disabled the USB-OTG in the kernel, the system has never rebooted. Btw I also re-loaded Angstrom image (3.8 kernel) and Andrew's Android image (with 3.8 kernel). I did not observe USB-OTG prob

By the way when I connected 5vdc directly to the additional ldo ic I have grounded Vusb as well and the board worked without any reboot issue during 1 week.

Follow your finding on the unexpected TPS65217C behavior, I patched the tps65217 driver with irq handling. The 3.2 kernel does not handle nNMI/PMIC_INT interrupt; the 3.8 kernel does. I placed printk in the interrupt handler and got the same result as yours. The PMIC_INT was issued every 2 seco

Re: [beagleboard] Re: [Issue] BeagleBone Black Random Reboot

I have soldered a 15 ohm power resistor between SYS_5V (P9.8) and DGND (P9.2). This increases SYS_5V load by 333mA. After three days of test I can confirm that random reboot frequency have not changed so it seems that the current load is not the problem. BTW: I have found and unexpected TPS6521

[beagleboard] Re: [Issue] BeagleBone Black Random Reboot

I have captured a BBB A5B random reboot with the oscilloscope (see attached image). Ch1 → VDD_3V3B (P9.4) Ch2 → VDD_5V (P9.6) Ch3 → SYS_5V (P9.8) Ch4 → SYS_RESETn (P9.10) This confirms that the random reboot is produced by 1 second SYS_5V fall. Best regards. 2013/11/20 > After readi

Re: [beagleboard] Re: [Issue] BeagleBone Black Random Reboot

I don't think that connecting a USB cable reduces the current load to the PMIC because there are two different switches in the power path for the AC and USB inputs. They can't be opened at the same time because the PMIC can't be sure that two sources have the same voltage. If both switches are open

[beagleboard] Re: [Issue] BeagleBone Black Random Reboot

My guess is that some piece of the kernel is setting PWR_EN low (see pages 15 & 16 in the TPS65217 Datasheet). This would explain the 1 second duration of the off state. The system could restart due to PWR_EN floating high. It does not explain why connecting to the USB power prevents the random

Re: [beagleboard] Re: [Issue] BeagleBone Black Random Reboot

I doubt the issue is connected with the floating nRESET pin. If you have a look at the "Figure 1. Global State Diagram" at page 16 the PMIC always waits for 1 second after a *FAULT*. Please read the following: FAULT = UVLO || OTS || PGOOD low|| PWR_EN pin not asserted within 5s of Wakeup event. If

Thanks for sharing the captured trace. It is very helpful. I wonder if you could further zoom in on the falling edge. I am really interested in the order of SYS_5V voltage drop and SYS_RESETn voltage drop. Also I noticed in TPS65217 datasheet, if the nRESET pin is pulled low, there will be a m

[beagleboard] Re: [Issue] BeagleBone Black Random Reboot

After reading the Jakub thread the new conclusion is that this seems to bee a hardware related problem (related to PMIC). This may explain why changing kernel or changing CPU frequency doesn't resolve the problem (only minimizes it). I will test the Jakub hardware workaround (external MOSFET)

[beagleboard] Re: [Issue] BeagleBone Black Random Reboot

It seems that Angstrom 3.8 kernel is more robust. But I couldn't confirm that it will resolve the random reboot issue. I haven't done long term testing. I remember seeing someone also has problem with it. It could be just that kernel is more optimized which draws less current. Limiting the CPU

[beagleboard] Re: [Issue] BeagleBone Black Random Reboot

Re: [beagleboard] Re: [Issue] BeagleBone Black Random Reboot

It could be a power 'level' issue. Most modern sound systems have a built-in kill switch. That if the volume spikes the speakers are turned off to prevent damage.. A similar system is probably in the BBB that prevents it from *receiving* to much power. It has to be something like that because o

Re: [beagleboard] Re: [Issue] BeagleBone Black Random Reboot

I think Robert is correct. I fetched a snapshot of u-boot (2013.10), build and dropped it in. It seems that the time jump problem is going away. I also did some testing with TI's kernel. I disabled the OPPs at 1G, 720M, and 600MHz. So the highest OPP is 500MHz. It seems that BBB is running much

Re: [beagleboard] Re: [Issue] BeagleBone Black Random Reboot

You will not burn the board but Nothing will change because when powering the board by a usb port the software limits the current to some level and when this limit is exceeded then the board reboots. Therefore even if you give 100A to the usb port the pmic will limit it 29 окт. 2013 г. 9:47 пользов
