Hello,

just copy the file to ffsdisk and change Registry value for DLL under HKLM/drivers/builtin/QBissA9r2/UART<x>. Ffsdisk is a search path but if you would like to use the default name "csp_serial.dll" (this file is still under \windows) you have to…

Thanks for the csp file with the increased buffer, however we don't make the OS image ourselves. Can I somehow use this file and load it on the system? Or can you build the image with the increased buffer so I can test it?

Sorry I did not test it. I am still busy in other projects. But I await to get the same results as you uing .NET. So wilI trust your statements.

All UARTs on imx6 use the same size for HW buffer (32 bytes) also I see no other property which may cause…

Hello Mike,

unfortunately CAN-FD is not supported in platforms with i.MX6 processors.

Your F&S Support Team

'Overrun' error is sporadically shown on the r1 board that we use. On r2 error is always thrown.
This overrun has to do with the HW buffer or OS driver buffer. Not the application SW buffer.
Have you done these test?

Good day,

we would like to run some tests on CAN-FD communication.
Is CAN-FD supported on the PicoMOD A9?
Is this merely a software change, or do we need to take note of certain changes during the buildroot build?

Best regards

Exactly what I needed, thank you!

The main reason for the busy error to appear is that in the default device tree, we enable SPI_B which claims the gpio pin. In the device tree under arm/boot/dts/efusa9x.dts you will need to make sure CONFIG_EFUSA9X_SPI_B and…

Hello,

to use the GPIOs, the IOMUX registers of the pads must first be set to the GPIO. This is done in the device tree of the Linux kernel. Usually we have defines to enable or disable certain devices (e.g. SPI_B), but for the Pre-Release these are…

I have enabled pin 56 in A9X as a gpio pin and attempts to set it as output.
root@hub:/sys/class/gpio# echo 118 > export
sh: write error: Device or resource busy

Despite my best attempts, I seem to be unable to use this as a gpio pin.
I checked the…
