Hello.
I have a problem, as described in topic head. 6.40.4 version needs 7mb, I have only 4.1 free. What to do?
Delete some files?
Files manu show that there is no files, same situation with packages.
The free measurement only describes the amount of non-volatile storage (“flash/“) that is free. However you can also place files outside of the flash folder. Those will be resident in memory, so they will be volatile when the unit is rebooted, but there is much more space available there. That is where you place RouterOS updates, which are applied before the unit shuts down.
Does netinstall required hard reboot?
From netinstall guide:
Start the RouterBOARD device with the RESET button pushed, until you see the device in the Netinstall program interface. Then release the RESET button (around 15 seconds since power on).
That would imply that your memory is also nearly full. Does winbox indicate that? (You can right click on the top bar and add a memory display there to find out.)
If so, perhaps you can temporarily make a configuration change that would reduce your memory usage, such as packet buffering in queuing, deleting older massive log files, etc.
In Files, perform a back up. Drag the back up out of winbox onto your PC. Perform a netinstall. Drag the back up back onto your router, and restore it.
Netinstall has a “Keep old configuration” switch. Keep in mind, you only need to upgrade your router if you use any of the station modes on wlan interface.
Either hold the reset button in as you apply power, and keep it in for 20 seconds, or set the System / Routerboard / Settings / Boot Protocol to try-ethernet-once-then-nand before rebooting. MikroTIk has Wiki pages that describe all this.
go to System - Routerboard - Settings:
select: boot device=try-ehternet-once…
so routerboard starts in netinstall mode only next reboot and u should be able to use netinall and flash the new firmware,
for me it worked until now perfekt on my little hap lite.
PS: with netinstall (with standard settings) you won’t lose your date or config!!!
it is only an update
