Documentation UP Xtreme i12

up_the_sky

I recently bought several up Xtreme i12 and need to understand the pin-out of the board. E.g. what is the Linux sysfs gpios for the 40 pin header? I tried the Xtreme i11 instructions, but the pin numbering doesn't seem to be the same.

Could this please be added, including pwm, i2c, spi Info and examples?

Hi Sir,

Some files are in the following URLs. I will ask internal staff to update the HAT40 corresponding Mapping you need to the website as soon as possible.

That would be awesome, thank you!

Hi Sir,

At present, we have updated the i12 settings on pinctrl, you can use it first.

So do we still need to update the BIOS and kernel first for the GPIO pins to work? I see a downloadable BIOS update in the first link you provided, but no instructions.

Hi Sir,

There is no need to update the BIOS.
Before the official shipment, we will go through the development stage to ensure that the hardware behaviors are all actionable.
So as long as it is the shipping version, GPIO must be able to work normally.
At present, the official version of BIOS has been tested and verified, and the GPIO can work normally and be used. Please install pinctrl directly to use it.

Best Regards.
