    <p>Hi,</p>
    <p>Sorry for the inconvenience, but I'd like to insist on this topic
      since it didn't get much traction on the first attempt.</p>
    <p>I mostly succeeded in adding support for the COMFAST CF-E313AC
      devices, but I ran into a couple of issues:</p>
    <p>1) I need to remove the board-2.bin file shipped with the
      ath10k-firmware-qca9888-ct so that the driver uses the actual
      calibration data from the flash, dumped to board.bin (<a
        moz-do-not-send="true"

        [1]</a>)</p>
    <p>2) the device has a 16MB SPI flash chip, but the stock firmware
      only uses the first 8 MB, so I'm wasting the remaining 8 MB</p>
    <p><br>
    </p>
    <p>I'd appreciate any comment on the topic. I also opened a pull
      request (<a moz-do-not-send="true"

      at GitHub, where you're also very welcome to share your thoughts.<br>

      <pre class="moz-quote-pre" wrap="">Hi,

I've just added support for the COMFAST CF-E313AC, an  outdoor wireless
CPE with two Ethernet ports and a 802.11ac radio (see patch below).

Everything is working fine but I've got two issues for which I'd like to
get some advise:

1) target/linux/ath79/base-files/etc/hotplug.d/firmware/11-ath10k-caldata

   I had to add "rm /lib/firmware/ath10k/QCA9888/hw2.0/board-2.bin", since
   the driver tries to board-2.bin (the default calibration data from the
   firmware package) first and, when that file is not found, falls back to
   board.bin (the calibration data read from the flash).

   I haven't seen this on any other device, so I guess there must be a more
   elegant way to deal with it. Any idea?

2) target/linux/ath79/dts/qca9531_comfast_cf-e313ac.dts

   The device is equipped with a "w25q128" flash chip (16384 Kbytes) but the
   stock firmware image only used half of it (nvram partition finishes at
   0x000000800000, i.e., 8192 Kbytes):

   *** stock firmware bootlog ***
    [...]
   [    0.730000] 0x000000000000-0x000000010000 : "u-boot"
   [    0.740000] 0x000000010000-0x000000020000 : "art"
   [    0.740000] 0x000000020000-0x0000001a0000 : "kernel"
   [    0.750000] 0x0000001a0000-0x0000007e0000 : "rootfs"
   [    0.760000] mtd: device 3 (rootfs) set to be root filesystem
   [    0.760000] 1 squashfs-split partitions found on MTD device rootfs
   [    0.770000] 0x0000006c0000-0x0000007e0000 : "rootfs_data"
   [    0.780000] 0x0000007e0000-0x0000007f0000 : "configs"
   [    0.780000] 0x0000007f0000-0x000000800000 : "nvram"
   [    0.790000] 0x000000020000-0x0000007e0000 : "firmware"
    [...]

   Is there a way to use the remaining half of the flash?


Any comments regarding these or other issues will be highly appreciated.

Thanks!
