ARM Trusted Firmware and date time related problems
#5
Finally I can report the iusse and my actual solution.

The system clock goes out of sync. Always step forward. I use ntp every hour to stay in sync. But this solutions only work when I use a fixed cpu clock speed.
When I use mainline kernel, the cpu is working always at the same speed 816Mhz. When I work with legacy kernel, I must use cpufrequtils to fix the cpu clock speed.

I'm actuallky testing to use a min value of 816Mhz and a Max value of 1,15Ghz

But if I use min value of 408Mhz and Max value of 1,15Ghz the clock step forward in a way that using ntpd could not step backware the system clock

I use a heatskin on the processor and power the board with the euler connector. The board has 1GB RAM and the gigabyte ethernet is working flawlessly.

My board is the only one affectec with this bug ?

Regards, Gustavo.
