Subject: Can't set MX6UL_PAD_LCD_DATA10 register with devicetree
Date: Fri, 5 Oct 2018 14:45:19 +0200 [thread overview]
Message-ID: <20181005124519.GA7699@graute-opti> (raw)
Hello list,
I try to set the following PAD in my imx6ul devicetree (derived from
imx6ul-14x14-evk.dts)
MX6UL_PAD_LCD_DATA10__GPIO3_IO15 0x100b0
but after kernel compiling and booting the register value is not
changed. A readout with devmem2 show me the wrong value.
devmem2 0x020E03CC
/dev/mem opened.
Memory mapped at address 0x76fc4000.
Read at address 0x020E03CC (0x76fc43cc): 0x000010B0
Setting the register manually with devmem2 just works fine.
/usr/bin/devmem2 0x020E03CC w 0x000100B0
other PADs like MX6UL_PAD_GPIO1_IO07__ENET1_MDC I could configure via
the imx6ul devicetree.
ideas what I'm doing wrong here?
Best Regards,
Oliver
