I am running Genode on i.mx53 QSB and was wondering to use a fingerprint scanner such as Adafruit finger print reader to create a virtual fingerprint. Is there any a device driver and library in Genode for a fingerprint scanner? Could you please tell me how to use it? Thanks in advance.

Please provide more information about the device you like to connect to the i.MX53 QSB. Is it a USB device or connected by other means? How does Linux drive the hardware device? Does it just need a low-level driver or are additional libaries required?

Regards

Hi Christian,

Thanks for your reply,

I wanted to use Adafruit Fingerprint sensor which can be connected to Arduino Uno micro-controller with TTL serial. Then I will connect the Arduino to the i.MX53 QSB via USB. Here you can find the Adafruit-fingerprint-sensor-library https://github.com/adafruit/Adafruit-Fingerprint-Sensor-Library.

Well, we do not have USB host controller support for the i.MX53 yet. So in this case you will need to first port that driver.

Alternatively, and maybe less complicated would be to connect the Fingerprint sensor directly to a second UART of the i.MX53 QSB. AFAIK there are two additional UARTs available via the expansion header (j13). Of course you would need a corresponding connector[1], and propably have to configure the IOMUX controller within our platform driver appropriatedly to use the additional UART.

In the end you have to port the Fingerprint sensor library.

It would be also great if you might have other fingerprint sensors that can be used integrated with the i.MX53 QSB board running Genode.

I'm not sure what you mean with "integrated". AFAIK there is no fingerprint sensor on this board available, or is it?

Regards Stefan

[1] In the Hardware manual I've found this paragraph: "The proper connector to mate with Expansion Port J13 is made by Samtec, QTH‐060‐XX‐L‐D‐A, where XX determines the height of the connector."

Thanks, John
