eMMC flash memory reliability - Raspberry Pi Forums

-

are there data out there show how reliable cms emmc flash memory chip is?

cm3 mounts samsung klm4g1fepd flash chip couldn't find useful information on number of read/write operations before flash gets corrupted. integrated controller perform wear leveling? how chip perform compared microsd card?

has here run stress test check durability of chip?

product design quite important information can't seem find anywhere.

flash suppliers reluctant release information this, since data dependent on use case. in fact don't release it. also, raspberry pi change flash suppliers on time, vary in way. 1 thing valid reliability higher flash cards, since uses mlc rather tlc flash., order of magnitude more robust. can mitigate lifetime issues reducing flash writes easily.

hey everyone, i'm trying compile simple code on rpi3 using geany. code written using code::blocks on windows , working without problem. errors i'm getting are: untitled.c:33:5: error: ‘for’ loop initial declarations allowed in c99 or c11 mode , untitled.c:33:5: note: use option -std=c99, -std=gnu99, -std=c11 or -std=gnu11 compile code understand code not problem way i'm compiling it. can give me advice? you need add 1 of suggested options compile command configured in geany, in menu.. build -> set build commands add "-std=c99" after "gcc" in compile , build boxes. (i'm looking on mint pc expect version on pi same). petero raspberrypi
