I have solved this problem. I am using LEDE Linux version 4.4.61. Device is a WF-96A from CIG shanghai.
WF-96A write calibration data in spi flash. I have success read it to `ath10k/cal-pci-0000:00:00.0.bin`. LEDE default use firmware-5.bin for QCA988X. But `ath10k/cal-pci-0000:00:00.0.bin` can only work with firmware-4.bin. What is the full name of otp? How does otp work? Should we pay attention to the version of calibration and firmware ? 2017-04-20 14:27 GMT+08:00 Kalle Valo <kv...@qca.qualcomm.com>: > 孙建希 <ycsunj...@gmail.com> writes: > >> The driver terminates execution in the function >> 'ath10k_download_cal_data`. `ath10k_download_cal_data` try load the >> ` pre_cal_file` and `cal_file` files via hif.
