Hi list,
I'm using a s32g274a-evb and i try to use the button available on the mother board S32GRV-PLATEVB.
The document SCH-30081 (Rev D.) describes on the OpenSDA Interface's page (the 20th) a button available which could be configured with the jumper J67 (position 2-3) to i quote "enable button when OpenSDA is not powered".
What does that means? Can i use this button connected on that gpio accessible through /sys/kernel/debug/gpio?
I seems that this button is accessible through *SDA_GPIO0* but i don't see any connection to the chip (as opposite of SDA_GPIO0_B..)
I use the kernel branch *tags/bsp31.0-5.4-rt* with the configuration created by *s32gen1_defconfig* and the dtb file *fsl-s32g2xxa-evb.dtb*.
Is it the right dtb for the manipulation? Should i use an other dtb or modify the current one to support the button connected to this gpio?
Let me know if you already try this setting.
Regards.
