FT232RL Unexplainable anomaly
« on: April 14, 2022, 09:45:13 AM »

I met with very strange anomaly.
Analog Device developed Arduino-like board: Linduino for communicating and testing their demo kits.
It differs from common Arduino UNO boards by using FT232RL chips
for serial-to-USB converter instead of native one.
So, any Arduino UNO could be converted to Linduino by changing serial to USB
 chip to FT232RL.
Prior to using FT232RL in Linduino AD recommends to change default chip setting according
their Template(attached).

I used Arduino UNO in form of Odroid U3 I/O
Shield(https://wiki.odroid.com/old_product/odroid-x_u_q/odroid_u3/u3_io_shield)
and wide spread USB-to-TTL FT232RL based adapter.

The problem is that from about 10 tested serial-to-usb converter boards,
based on the same FT232RL chip, only one recognised by Analog Devices softwares(https://ltspice.analog.com/software/ltcqev.exe) as Linduino.
This is the only difference. In all other functionalities all adapters are the same.

All used FT232RL chips are definitelly original not clones.

As I understand AD SW uses non traditional low level approch in VCP
drivers, because I could not snif serial communications with
corresponding SW( e.g. IO Ninja from Tibbo Tech https://ioninja.com )

I guess, this moment should be of particular interest to FTDI engineers.

Thanks in advance,
Vladimir

Hi
Since this is not one of our products, we are unable to support it.
Product Manufacturers are responsible for supporting end-users of their products.
FTDI cannot control how the USB ICs are used and often has no knowledge of the entire product.
Please see the following document for reference:

https://ftdichip.com/wp-content/uploads/2020/08/TN_102_OEM_Technical_Support_Requirements_for_FTDI_Products.pdf

You should contact Analog Devices with regard to their software
