So, when more flash space is required, a sysupgrade image can be flashed right after factory, to allow for using of all the available flash memory.

Did you Double Flash to obtain the max available flash space?

"The recovery also does not have the minimum size requirement, however we shall prefer not to have three separate images (factory padded for web-flashing, factory unpadded for recovery, sysupgrade) when the padded factory image is also accepted by the recovery (but requires double flashing to use all of the available flash space)"

Yes, I double flashed, choosing not to keep the settings (to be sure)

Do a reset -

Just resetted. Still missing.

Care for a Side Track.. possible to peek at
to see if any kmod-ath10k* are relevant?

maybe i could install kmod-ath10k package, but how can I check if the other radio become available?

Do you mean the 5GHz? If so you install the package and a reload or possibly a restart, then look for a 5GHz radio.

it should be listed with the iw list command?
isn't there a command to check the periphericals like lspci in linux?

After a reboot iw list shows always a single radio

Correct if the device was present it would have shown with that command.

IDK of the other command lspci

Is that after installing the kmod-ath10k package ?

... so we're still broke ....

Description: Alternative ath10k firmware for QCA99x0 from Candela Technologies.\ Enables IBSS and other features. See:\ http://www.candelatech.com/ath10k-10.4.php \ This firmware conflicts with the standard 99x0 firmware, so select only\ one. \ \


Yes, after installing kmod-ath10k and ath10k-firmware-qca99x0 still no 5GHz radio

Just for curiosity let's see the output posted in preformatted text

ubus call system board

You're overdue for some fortune..

Default ath10k-ct packages were installed -

Reflash the router with the squashfs-sysupgrade image.

Guys - before doing any of that, you first check the low level stuff. The radio doesn't show up in the wireless configuration - so you want to check dmesg or logread for any pointers on hardware not being detected or initialisation failure.
