hi,

i see the setup_sdcard.sh, it almost used for TI board , and for freescale's chip, only have three:IMX51,IMX53, mx6qsabrelite;

and mx6qsabrelite is a four core processor, i think maybe it is different for imx6solo processor, so there is a reason why the memory leak when run on this rootfs.

who known the details for difference, please tell me.

thanks.

Did you build user-space application? When you close the app (control +c, not kill) , does the free memory never increase to its original value?

at first i run some script on it,but when i do nongthing after the board power on, it still have memory leak.

i use top command find there have 61 thread runing. and then i use jobs command to check there is not app was stop or halt.

then i think maybe the kernel that compiled have some problem.

but i dont familiar the kernel and boot to refresh, because the other colleage who do these things out of office some days .

i run the all of code on sd-card. i remember there maybe three part need to download sd card:rootfs,uboot and uimage.

i found a program named setup_sdcard.sh, but i donot know how to use it for my i.mx6solo board.

if you have these detail information for me, will be very thanks.
