板子调试串口从 1改到 4
我做了如下修改
mx6qsabresd.c :
iomux_v3_cfg_t const uart4_pads[] = {
MX6_PAD_CSI0_DAT12__UART4_TXD | MUX_PAD_CTRL(UART_PAD_CTRL),
MX6_PAD_CSI0_DAT13__UART4_RXD | MUX_PAD_CTRL(UART_PAD_CTRL),
};
static void setup_iomux_uart(void)
{
// imx_iomux_v3_setup_multiple_pads(uart1_pads, ARRAY_SIZE(uart1_pads));
imx_iomux_v3_setup_multiple_pads(uart4_pads, ARRAY_SIZE(uart4_pads));
}
mx6qsabresd.h :
#define CONFIG_MXC_UART_BASE UART4_BASE
#define CONFIG_CONSOLE_DEV "ttymxc3"
还是看不到串口4的打印信息，请问还要修改什么地方，谢谢 |
