ATI shows firmware version of 1.0.2.
AT!FLOG? shows:

I think firmware on my EM7565 is very old and may have issue in upgrading firmware.

Also, I found this:

[Solved] EM7565 Firmware Update from 01.00.02.00 to 01.07.00.00

Dear all, I desperately try to update the firmware of an EM7565 module. The sdk’s firmware download tool reports the following output, when trying to upgrade the firmware to 01.07.00.00: [root@X250RF bin]# ./fwdldhostx86_64 -s ../../../build/bin/hostx86_64/slqssdk -d 9x50 -p fw Detecting USB of the target DONE Communicating with the target DONE Switching to firmware download mode ...............Firmware Not Downloaded (Not Required) ...............ERROR: Failed t…

As described in above, I am able to upgrade to version 1.7.2, but only under Windows. Upgrading in Linux still does not work. But I think it doesn’t matter at this point.

Thanks,
Shuo
