Hello everyone.
How can I test the ports?
It is impossible not to write or read.
In board-mx6q_var_som.h :
static iomux_v3_cfg_t mx6q_var_som_pads[] = {
...
/* UART1 for debug */
MX6Q_PAD_CSI0_DAT10__UART1_TXD,
MX6Q_PAD_CSI0_DAT11__UART1_RXD,
/* UART2 for for Bluetooth */
MX6Q_PAD_EIM_D28__UART2_CTS,
MX6Q_PAD_EIM_D29__UART2_RTS,
MX6Q_PAD_SD3_DAT4__UART2_RXD,
MX6Q_PAD_SD3_DAT5__UART2_TXD,
/* UART3 for RS232 port */
MX6Q_PAD_EIM_D23__UART3_CTS,
MX6Q_PAD_EIM_EB3__UART3_RTS,
MX6Q_PAD_EIM_D25__UART3_RXD,
MX6Q_PAD_EIM_D24__UART3_TXD,
...
}
Tell me what I need to do to test the operation of these ports?
