Safe way to update piCore?
« on: June 06, 2013, 01:42:34 AM »
I installed piCore-20130331 w/o realizing that piCore-20130521 had been released (it'd not linked on Download page).   Is it safe to update this way?

  • gunzip & mount piCore-20130521.img
  • copy kernel3813a.img & piCore3813a.gz to the FAT partition
  • update config.txt to point to the new files
  • reboot

Best is to delete all existing files on mmcblk0p1 and copy all files from the new image's mmcblk0p1

Not sure what I did, but deleting all the files on mmcblk0p1 and copying the new files didn't work. :/  There isn't anything about sector locations of file wrt to the bootloader, right?  I ended up overwriting and starting from scratch.  Disappointed the new kernel doesn't set the cpuinfo bogomips to what might seem more reasonable.

What is your problem with bogomips? It shows the 2.00 which is correct. Its definitions is changed:

Quote
For platforms that use a fixed timer for delays bogomips is now defined to be:
TIMER_FREQ/500000. We have TIMER_FREQ=1000000 and so bogomips = 2.

bogomips has no any releationship to system performance.
