Hi,

Could you share your pinmux file?

Hi,

I meant the the cfg file you copy to Linux_for_Tegra/bootloader/t186ref/BCT/.

ok.
I replace “tegra186-mb1-bct-pad-quill-p3310-1000-c03.cfg” with “tegra186-mb1-bct-pad-quill-char-e3301-1080-a00.cfg.txt”, and “tegra18x-jetson-tx2-config-template-pinmux.dtsi.txt” with “tegra186-quill-p3310-1000-a00-pinmux-gpio.cfg.txt”

Hi,

Do you also see some numbers in these txt file on your side? They should not be here.

I have flash successed. I’m sorry, I change pinmux-dts2cfg.py and add some print in code. So how do I make sure my configuration is working? I custom the below pins as Bidirectional gpio in J21 on carrier board. Thank you very much.
