masayuki2009 opened a new pull request #2707:
URL: https://github.com/apache/incubator-nuttx/pull/2707


   ## Summary
   
   - During stress test with spresense:wifi (non-SMP), I noticed
     sometimes ASSERT() happened in _read_data_len()
   - Actually, up_udelay(50) has been added to avoid the ASSERT
   - However, I finally noticed that it should be moved before
     calling dready()
   - Also, I cofirmed that we can reduced the time from 50 to 30
   - NOTE: we need at least 15us in my experience
   
   ## Impact
   
   - gs2200m.c only
   
   ## Testing
   
   - Tested with following configurations
   - spresense:wifi, spresense:wifi_smp, stm32f4discovery:wifi
