AM335x system time issue

user3469252

Hi,experts:

We have run the sdk6.0 on custom board,the processor is AM3354ZCZA100.

It looks like all is normal but the system time,

The system time automatically increas at intervals,It seems like a random value.
about 10 hours after the system is running,the system time and rtc time are as follows:

[root@schz app]#date
Sun Aug 21 16:26:50 UTC 2016
[root@schz app]#hwclock
Thu Jul 28 09:54:18 2016 0.000000 seconds
[root@schz app]#

I don't know what the problem is ,Look forward to your reply.
thanks!

Hi,

SDK 6.0 is old, no longer maintained and not recommended for new designs. Check if this issue still exists with the latest SDK: software-dl.ti.com/.../index_FDS.html

Hi Biser!

thank you for you reply at first!

at present,we can't upgrade sdk to higher version due to stability of the product.

The system time issue has been resolved.

1. crystal circuit is connected directly to digital ground according to advisory 1.0.30.

2. switch system timer source to 24M in timer.c .

But USB is still not working due to the Babble Interrupt.

any idea?

thanks!
