GPIO1 issue

marekvysocky — Wed, 19 Apr 2017 11:09:28 GMT

Hi,
On i.MX6UL I cannot set CSI DATA 5 pin as a GPIO1 DATA19 output.

I set IOMUX, GPIO_GDIR:
HW_IOMUXC_SW_PAD_CTL_PAD_CSI_DATA05_SET(IOMUXC_BASE, 0x05UL);
HW_IOMUXC_SW_PAD_CTL_PAD_CSI_DATA05_CLR(IOMUXC_BASE, 0x0AUL);

HW_GPIO_GDIR_SET(GPIO1_BASE, (1u << 19));
HW_GPIO_DR_SET(GPIO1_BASE, (1u << 19));
but it doesn't do anything. What is wrong ?

Hi Marek

seems there is some confusion for mux options for CSI_DATA05 pad, available options are
described on sect.30.5.122 SW_MUX_CTL_PAD_CSI_DATA05 SW MUX Control
Register (IOMUXC_SW_MUX_CTL_PAD_CSI_DATA05) i.MX6UL Reference Manual

Dear Igor.

You are my salvation. Thank you again. Problem (chaos) is in iMX6UL_registers.h file Copyright (c) 2014 - 2015, Freescale Semiconductor, Inc. All rights reserved. This file is part of IAR Embedded Workbench.
