From a1ed155298eeb29000d9b1033be094c0f7c45212 Mon Sep 17 00:00:00 2001 From: Michael Schanz Date: Thu, 10 Dec 2015 09:58:35 +0100 Subject: cgtqmx6eval: fix pad configuration for SPI bus Use the macro SETUP_IOMUX_PAD(...) rather than imx_iomux_v3_setup_multiple_pads(...) in order to setup the pin configuration for ECSPI1. ARRAY_SIZE(pads) provides the wrong size for imx_iomux_v3_setup_multiple_pads(pads, ARRAY_SIZE(pads)) in case of MX6QDL. In the particular case, the content of GPR12 is overwritten and the IPG/AHB/ATB/ATP clocks are deactivated. Therefore, the connection to the system via JTAG is not possible anymore. Furthermore, kernel version 3.0.35 hangs during bootprocess in the function etm_init().
