##Problem description After setting the hardware RTC with the command:

# hwclock -w

after just few minutes the RTC already lost seconds with the command:

# hwclock -r

##Solution This problem is due to an error in the AT91Bootstrap configuration. We missing to set this flag during the make menuconfig setup (see [Compile AT91Bootstrap](/compile_at91bootstrap)). The right configuration is this: Slow Clock Configuration Options ---> [*] Use external 32KHZ oscillator as source of slow clock [ ] Use external 32kHz clock as source of slow clock You can re-compile the AT91Bootstrap following this article: * [Compile AT91Bootstrap](/compile_at91bootstrap)
or simply change boot.bin in the first partition of microSD with the binaries file available on the [same page](./compile_at91bootstrap)
