I'm trying the Orange Pi PC for a smal project but while installing th OpiPC corrupts its SD Card.
Typical error occurence:
- Install Debian Jessy server on 16GB SD Card (ScanDisk Ultra class 10).
- run first bootup.
- update und upgrade software, install nfs-common and rrdtool.
- setup keyboard, console-setup, tzdata, locales, static ip.
- edit /etc/fstab, mount nfs-volume.
- copy project software (mostly bash scripts, reading cpu temp and switching GPIO-Pin).
- seting up a cron job.
on one of the next shutdown/reboot the console shows mmc errors while reading and writing (see log file).
- the Sd card can not be started any more, all attempts fail with mmc read and write erros.
- reinstalling the image on the same SD card allows me to start over again. On first Boot no errors are shown.
tested variations:
- after the crash the SD card can be tested with badblocks on a different system; no errors shown
- 3 other SD cards (32GB class10) show the same results
- Using an industrie standard power supply with 3 different voltages (4,5V, 5V, 5,5V) show the same errors
- using Orange Pi Plus, no errors are shown (not within the firs 3 days and many reboots).
- using other linux builds from orangepi.org or laboris do not show this efect.
Is there any thing in /boot/scrip.bin that sets mmc timing ?
Any other idear ?
Greetings Eddy
