Hi,
Can you provide your kernel config? Also enabled kernel memory leak debugger to check if there' s memory leak. Thanks.
Sincerely,
Yi-An Chen
how to enable kernel memory leak debugger? could you provide your email address? I don't know why I can't add attachments here. thanks
Hi,
Enable CONFIG_DEBUG_KMEMLEAK, rebuild kernel. And execute in shell. mount -t debugfs nodev /sys/kernel/debug/ cat /sys/kernel/debug/kmemleak
You can paste your config as plan text here in this thread.
Sincerely,
Yi-An Chen

1、have configed: (1)kernel debugging (2) kernel memory leak detector 2、recompiled and downloaded 3、but kernel print: kmemleak:kernel memory leak detector disabled kmemleak:early log buffer exceeded (2034),please increase DEBUG_KMEMLEAK_EARLY_LOG_SIZE
so last cannot found kmemleak in /sys/kernel/debug. which steps are ignored; thanks
Hi,
As the log message shows, please try to increase DEBUG_KMEMLEAK_EARLY_LOG_SIZE and test again. Thanks.

Hi, Please try to use initrd as rootfs and mount yaffs2 partition manually. If it failed to mount manually, probably the yaffs2 partition is not write into NAND correctly.
Close unless there's new feedback.
