Hi, I'm using i.MX6 sabresd for my layer.
I wanna show the debug message from uart2 during mfgtool burning.
I've settings my dts under mfgtool-linux-imx/4.1.15-r0/git/arch/arm/boot/dts/XXX.dts
Also I modify the mx6sabresd.c which is located at u-boot-imx/2015.04-r0/git/board/freescale/mx6sabresd/.
This is what I try to modified.
static iomux_v3_cfg_t const uart1_pads[] = {
MX6_PAD_CSI0_DAT10__UART1_TX_DATA | MUX_PAD_CTRL(UART_PAD_CTRL),
MX6_PAD_CSI0_DAT11__UART1_RX_DATA | MUX_PAD_CTRL(UART_PAD_CTRL),
};/*ttymxc0*/
to
static iomux_v3_cfg_t const uart1_pads[] = {
MX6_PAD_EIM_D26__UART2_TX_DATA | MUX_PAD_CTRL(UART_PAD_CTRL),
MX6_PAD_EIM_D27__UART2_RX_DATA | MUX_PAD_CTRL(UART_PAD_CTRL),
MX6_PAD_EIM_A25__GPIO5_IO02 | MUX_PAD_CTRL(NO_PAD_CTRL),
};/*ttymxc1*/
Besides, I also modify this two file which are mx6sabre_common.h and mx6sabresd.h.
Below is what I have modified.
For mx6sabre_common.h
#define CONFIG_CONS_INDEX 1
to
#define CONFIG_CONS_INDEX 2 /*1 to 2*/
For mx6sabresd.h
#define CONFIG_MXC_UART_BASE UART1_BASE
#define CONFIG_CONSOLE_DEV "ttymxc0"
to
#define CONFIG_MXC_UART_BASE UART2_BASE /*UART1_BASE to UART2_BASE*/
#define CONFIG_CONSOLE_DEV "ttymxc1" /*ttymxc0 to ttymxc1*/
But I still cannot show the debug message.
However I can show the kernel message after I burning the image and reboot the system.
How can I solve this problem?
Thanks in Advanced!
