Hello,
I am trying to test UART on IDK437x board.
I have created UART_BasicExample_idkAM437x_armTestProject.
And as per the it UART0 is working fine.
UART0:
RX: K25
TX: J24
Now I want to test UART1.
AM437X_PROFI_TXD
AM437X_PROFI_RXD
UART1:
RX: K21
TX: L21
To do that I have only changed the instance 1 from 0.
static void UART_initConfig(bool dmaMode)
{
UART_HwAttrs uart_cfg;
uartTestInstance = 1;/*For testing UART 1*/
/* Get the default UART init configurations */
UART_socGetInitCfg(uartTestInstance, &uart_cfg);
int32_t UART_socGetInitCfg(uint32_t index, UART_HwAttrs *cfg)
{
int32_t ret = 0;
if (index < CSL_UART_PER_CNT_AM437X)
{
*cfg = uartInitCfg[index];
}
else
{
ret = -1;
}
UART_HwAttrs uartInitCfg[CSL_UART_PER_CNT_AM437X] =
{
{
SOC_UART0_REG,
104,
0,
48000000U,
CSL_EDMA3_CHA_UART0_RX,
CSL_EDMA3_CHA_UART0_TX,
0,
0,
0,
0,
0,
NULL,
UART_RXTRIGLVL_8,
UART_TXTRIGLVL_56,
TRUE, /* default DMA mode */
FALSE, /* Loopback disabled by default */
TRUE, /* Interrupt enabled by default */
UART16x_OPER_MODE, /* operMode, 16x over sampling mode by default */
},
{
SOC_UART1_REG,
105,
0,
48000000U,
CSL_EDMA3_CHA_UART1_RX,
CSL_EDMA3_CHA_UART1_TX,
0,
0,
0,
0,
0,
NULL,
UART_RXTRIGLVL_8,
UART_TXTRIGLVL_56,
TRUE, /* default DMA mode */
FALSE, /* Loopback disabled by default */
TRUE, /* Interrupt enabled by default */
UART16x_OPER_MODE,
},
Based on that it will initiate the UART1.
But it is not working as expected.
Kindly guide.
