I usd MCIMX6Q6AVT10AD in my design.
I want change my UART1,to SD3_DAT6、SD3_DAT7 port , I change the Uboot .Uboot is from mx6q_sabresd.
The file board\freescale\mx6q_sabresd\mx6q_sabresd.c
Before:
289： //mxc_iomux_v3_setup_pad(MX6Q_PAD_CSI0_DAT10__UART1_TXD);
293： //mxc_iomux_v3_setup_pad(MX6Q_PAD_CSI0_DAT11__UART1_RXD);
After:
//mxc_iomux_v3_setup_pad(MX6Q_PAD_CSI0_DAT10__UART1_TXD);
mxc_iomux_v3_setup_pad(MX6Q_PAD_SD3_DAT7__UART1_TXD);
//mxc_iomux_v3_setup_pad(MX6Q_PAD_CSI0_DAT11__UART1_RXD);
mxc_iomux_v3_setup_pad(MX6Q_PAD_SD3_DAT6__UART1_RXD);
When I Connected to a serial port ，My board start anomalies，The serial port without output 。THEN I disconnect the receiver，connect sender
，The serial port have output.but show me the execution interrupt in half.
what`s wrong ? what can I do?
Please help me and thank you!
