Mikrotik RBcAPGi-5acD2nD (cAP ac)

Installing and Using OpenWrt
1

Hi,

I ‘ve two access points (second hand) as in topic subject and by table of hardware is declared to use 24.10.5-ipq40xx.

I tried to use the 25.12.2 I booted from that and it seems to work ok.

Unfortunately I couldn’t boot in original firmware , I don’t know why… therefore I do not know what RouterOS version I have.

Which sysupgrade I would have to use mikrotik_cap-ac-squashfs-sysupgrade.bin or mikrotik_cap-ac-squashfs-sysupgrade-v7.bin ???

If I do a wrong thing, can I reset and back to original state? I mean .. if I flash a wrong firmware can reset all thigs?

Thanks for you time

Gabriele

These devices can be locked down through protected‑routerboot, but if you can boot initramfs you are fine. Can use Mikrotik netinstall if you need stock.

From OpenWrt, you can get your backup and primary RouterBoot versions from:
for i in /sys/firmware/mikrotik/*/*version; do echo echo $i; cat $i ; done

Does not matter, only that v6 will not boot on v7 RouterBoot. v7 should work with any v6 or v7 RouterBoot. If is does not boot from flash, check that the bootloader is set to boot from flash first flasheth in the OpenWrt sysfs driver /sys/firmware/mikrotik/soft_config/boot_device.

Yes, as long as you are using the firmware for correct device and sysupgrade, you can reset to stock (Mikrotik netinstall), or fresh OpenWrt (sysupgrade -n from initramfs), the bootloader and device-specific data parts on flash are not modified.

Thanks johnth,

I flashed v7 and all works.

Hi after a misconfiguration I’m off :frowning: … the AP doesn’t BOOTP/TFTP on tftp server when I press reset button before power on. Is it possible when I sysupgrade the firmware the BOOTP/TFTP doesn’t work anymore?

Watch the LED patterns (and look at Mikrotik manual) to make sure you are holding button long enough to get to that stage, it is a long time.

Hi I repeat and repeat all stages I did when I flashed the AP but nothing.. the tftp console doesn’t show anything. Are you sure when device is flashed with openwrt it would be boot tp again ?
