Hello, I was wondering if you could share your wiring connections. I'm struggling to get the UMFT4222EV to connect to a Riverdi BT817Q. My connections are as follows:
UMFT4222EV -> BT817Q
JP5.9 -> SCLK
JP5.8 -> MISO
JP5.7 -> MOSI
JP5.5 -> IO.2
JP5.4 -> IO.3
JP4.11 -> ----- 10k Resistor -> +3V3
JP4.9 -> CS 4.7k Resistor -> +3V3
JP4.6 -> INT
JP4.4 -> RST/PD
When in EAB and I try to Detect, I mostly get the following:
Detecting flash...
Found device: FT4222 A (A)
Host: FT4222
Flash size: 64 MBytes
Blob is NOT present.
Flash can switch to full speed.
END
Detection fail!
Occasionally, I get this:
Detecting flash...
Found device: FT4222 A (A)
Host: FT4222
Flash size: 64 MBytes
Blob is NOT present.
Flash can switch to full speed.
END
BEGIN
Measure reading speed...
Reading speed: 17.88 MB/s
Reading 10 MBytes in 0.56 seconds
END
In either case, it never finds the blob. I know the blob is present because I can program it perfectly fine with an FT232H.
Is something connected incorrectly? I've been trying to use the ME817EV schematic to try and match things up, which I think I have (using the pin mapping above).
Any insight would be greatly appreciated.
Kindest regards.
