Hi Victor,
For you question
Device: OMAP 335XSK board with ti1271 wifi chip.
Driver: I am porting from linux code(net/wireless/12xx)
Now I found this issue maybe caused with start_time in wl1271_tx_hw_descr. But I don't know how to set this value is correct. Now sometime I can send some package, but it is unstabitily.
Thanks for your messge.
