FT232H Read returns zero byte

["Ali Ebrahimi" <ali.ebrahimi@xxxxxx>]

Hello,

 

I have a FT232H chip connected to a FPGA. It is set to comunicate using the sync fifo mode. I used to have a software on Linux written based on the D2XX driver to communicate with the chip and everything was fine except that the troughput was limited to less than 10 MB/s.

 

Now I have switched to libftdi but ftdi_read_data() frequently (but not always) returns zero bytes. I have checked the mailing list archive and I guess my problem is very similar as the one discussed here:

http://developer.intra2net.com/mailarchive/html/libftdi/2010/msg00295.html

 

I checked the code of libftdi.c and the patch is not implemented there nor I can find any trace of it on the git. 

Would you please let me knwo what has happened to this patch? Also I would appreciate other suggestions to fix the problem.

 

best regards,
Ali
