Hello,
I recently purchased a control board that said it would work with my R4, It's a  ZYNQ C41   IT has the S9  firmware installed.   When I go to flash it with the R4 TAR.GZ files, it gives me an error.  I am not sure if there is a different file I can use to flash it or make a file for a bootable SD card.   The files on Bitmain don't seem to be files I can use to boot from the sd card.  Any help is greatly appreciated!   I don't think this should be this complicated.  Thank you in advance.
