Hello,

in out default configuration for the efus-STINF this pin is used as reset for the PCIe card, so it is an output.
If you are not using PCIe in your configuration, you can use this pin as GPIO.
You will have to to disable PCIE in your device tree and…

Dear F&S,

I came across a mismatch between the document efusA9_Hardware_eng and efusA9-GPIO-ReferenceCard_eng.

The pin 59 of the J1 connector is stated as "Output" pin by efusA9_Hardware_eng:



while the GPIO reference card says, it is an "IO" configurable…

Because of the urgency of the release, we updated and tested the pad configuration only for the kernel for now.

As you already mentioned, the U-Boot only runs for a couple of seconds and is mainly used in development.

Hello Stefan,

there is an errata entry for internal IO pullups/pulldowns in 3.3V operating mode: Mask Set Errata for Mask 0N87W (refer to ERR050080)

Because of this degradation we removed all unnecessary internal pullups and pulldowns in our latest release…

Alright thank you for the information on this errata!
We will only use external pullups/pulldowns for inputs from now on.

You removed the internal pull resistors in the kernel, but in the U-Boot devicetree from this release, they are still present.
Do you…

Hello,

we are running basic tests in our production for each board before flashing of the bootloader. eMMC should also be tested here.
Could you provide the following information via our support E-Mail (support@fs-net.de), so we can look into the logs…
