Hi,

 

I am working with BF527 Rev0.2 custom board uClinux distribution 2009R1-RC1.

 

I tried to set the time to blackfin RTC uisng the hwclock. utility/function.

 

The time taken to write into the RTC is almost 1 minute.

 

*************************************

 

time1

 

system("hwclock -w");

 

time2;

 

time2 - time1 = 65secs.

 

****************************************

 

Why is this happening? Is am doing doing anything wrong. Please help to solve this issue.

 

Thank you.

is your RTC wired correctly ?  can you read the correct time ?  can you read/write it under u-boot ?
