ISP mode, with external power supply, VCC, VCCQ.
External power supply is USB powered AMS1117 3,3V and AMS1117 1,8V voltage regulator mounted on test panel.
This is an unlimited UFPI box version with licenses for all current and future modules. Life-time warranty and support, free e-mail account at mslw.com. Good way to support UFPI project and forget about future modules activation’s. Sockets not included. UFPI Pro PCB inside! UFPI Pro supports operation with eMMC chips in 8-bit mode.
Don't worry. 4 bit UFPI will be faster than 8 bit competitors.
Today, I tested my RT809H, and 4GB emmc read 94 sec 8bit, and write 148 sec 8 bit, if I remember correctly
If I have time do screen shoot. Black UFPI do same time?
Thanks for reply.

Thanks for reply.
I also found such a description
A little math lesson for those who have forgotten how to count. 128/4=32. 32*94=3000 is not equal to 2197.
Go ahead and watch the trick: (128*2^30)/2197=62,5 MIB/s.
Is this a joke, or does the rt809 have usb3.0 and the frequency has become >100 MHz?)))
P.S. No one will be able to overtake ufpi, I'm sure, at least on usb2.0.

With eMMC in 8-bit mode all programmers (with HS USB2.0) will be limited with the same maximum speed ~37 MiB/sec. This is USB2 speed limit (+- 2MiB/sec, depends on PC). KiB it's 1024 bytes, MiB it's 1024 KiB.
If you are looking for faster speed's - turn on Async IO, and "One request" in Read mode menu and faster clock. And you can get good result in 4-bit mode, example:

Hi bbadmin,
Thanks for your answer, I will test your advice (turn on Async IO, and "One request" in Read mode menu and faster clock).
I have UFPI silver two licences (mount file, mount chip), but I like UFPI black, but I dont know it is good idea (UFPI black 400 dollars, and I will have two UFPI).
