OPi PCPlus eMMC testing utility?

Recommended Posts



Is there any testing utility/exerciser for OPi PCPlus eMMC?

I'm geting strange problems when fast and large writes happen in eMMC.






this is what I get by running 'armbianmonitor -c ~/healthtest'

iozone test complete.
touch: cannot touch ‘healthtest/cardtest.ZfDdZ7/.starttime’: No such file or directory

Test stopped, read-only filesystem

Please be careful using this media since it seems it's already broken. Exiting test.


appart from the "Average writing speed: 6.95 MB/s" is very low

..that final line is really alarming..


Any hints or relevant info on OPi PCPlus eMMC?
