Hello

I've installed SNAPSHOT r11495-261c746631 on an TP-Link 840N V4.
This device should have 64/8M but top shows only 32M and df 4M
top:

Mem: 29660K used, 30688K free, 288K shrd, 2688K buff, 7156K cached
df:
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/root                 3328      3328         0 100% /rom
tmpfs                    30172       288     29884   1% /tmp
/dev/mtdblock4            3264       328      2936  10% /overlay
overlayfs:/overlay        3264       328      2936  10% /
tmpfs                      512         0       512   0% /dev

but cat /proc/mem shows 64

MemTotal:          60348 kB

MemAvailable:      23328 kB
Buffers:            2880 kB
Cached:             7156 kB

So what's wrong the definition of this device?
How to debug or change config?

So what's wrong with your eyes?

About 29M used and about 30M free gives about 59M in summary. So looks like it has 64M RAM.

About 3.3M /rom and about 3.2M /overlay gives at least 6.5M useable flash for openwrt and filesystem. Assuming there are only flash sizes of 4M, 8M, 16M and 32M your device has at least a 8M flash chip.
