A bizarrerie problem in  no-OS driver for AD9371

Question asked by andy_wuu on Aug 11, 2017

I am trying  the on-OS driver for my adrv9371 evaluation board.   i do NOT modify any code.  the running result shows everything is OK but the rxFramerStatus ==0 and orxFrameStatus==0 (this two status should be 0x3E). 


i am stopped here for couple days.  by chance,i  found out  that the “printf”  imfact other code. i replace the "printf" with "xil_printf",  then result is OK.


but i have no idea WHY.   Anybody would tell me WHY? Thanks.
