i tried, but the result doesn't look better:

[    9.640000] ath10k: pci irq legacy irq_mode 0 reset_mode 0
[    9.730000] ath10k: otp calibration failed: 2
[   10.540000] ath10k: UART prints enabled
[   10.600000] ath10k: qca988x hw2.0 (0x4100016c, 0x043202ff) fw 
10.1.467-tplink-a-c7 api 2 htt 2.1

I removed the error return in ath10k, that's why the firmware starts 
even with the otp error. I don't see the Assertion failure with this otp 

CLI>build_version=0x11, rom_version=0x41020000, ram_version=0x11, 
reset reason=0x5

Just to be sure, here are the md5sums of the firmware files i'm using:
