Hi,
I need to get the system ticks since systemboot from reset, there is an API in VDK VDK_Getuptime();
I tried using the gettimeofday function, it is saying undefined reference for me, i think i am missing something/doing silly can anyone help me how to get the system ticks.
Best Regards,Sreedhar.

what exactly are you trying to do ? right a kernel driver or linux userspace application or ?

Hi Mike,
I want to use it in the kernel side.
I need to poll the PF pin for enabling the sport for avoiding the L/R channel swap anamoly in BF533.
In VDK we used VDK_Getuptime();
Can you please suggest me how to implement this.
Best Regards,Sreedhar.

Sreedhar:
Which anomaly are you talking about? All the existing anomalies should already have workarounds in the existing drivers.

Hi Robin,
Anamoly is : 05000265 ( It still applies to 0.5 silicon revisons also as per the anamoly sheet of ADSP BF531/532/533)
So i want to poll the PF pin for avoiding the Channel swap,
if this workaround is already implemented for any other revisions, can you please let me know the path where i can find the work around.
Best Regards,Sreedhar

i dont see how those three topics are related at all. the anomaly talks about poor board design leads to extra interrupts being fired. binding to interrupt a or interrupt b wont workaround the problem. simply "using VDK_Getuptime" wont change anything about the state either.
the end of the anomaly says that with 0.5+ silicon, you can enable the SPORT hysteresis function. we do this for all parts already with 2008R1+.
