Tool/software:
Hi,
I used G15 pin as RST signal to peripheral, its setting is:
and test it voltage level after initialization periodly.
static void enet_lwip_eth_rst(void)
{
uint32_t delayus = 100*1000;
uint32_t gpioBaseAddr, pinNum;
gpioBaseAddr = (uint32_t) AddrTranslateP_getLocalAddr(CONFIG_ETH_RST_BASE_ADDR);
pinNum = CONFIG_ETH_RST_PIN;
// GPIO_setDirMode(gpioBaseAddr , pinNum, GPIO_DIRECTION_OUTPUT);
while(1)
{
GPIO_pinWriteLow(gpioBaseAddr, pinNum);
if(GPIO_pinRead(gpioBaseAddr,pinNum) == GPIO_INTR_LEVEL_LOW)
printf("ping set to 0\n");
ClockP_usleep(delayus);
GPIO_pinWriteHigh(gpioBaseAddr, pinNum);
if(GPIO_pinRead(gpioBaseAddr,pinNum) == GPIO_INTR_LEVEL_HIGH)
printf("ping set to 1\n");
}
}
This function is called
int enet_lwip_example(void *args)
{
Enet_Type enetType;
uint32_t instId;
int32_t status;
printf("enet_lwip_example\n");
Drivers_open();
Board_driversOpen();
enet_lwip_eth_rst();
DebugP_log("==========================\r\n");
DebugP_log(" ENET LWIP App \r\n");
DebugP_log("==========================\r\n");
But the pin shows alway in high state. The log is:
[Cortex_R5_0] FreeRTOS main started enet_lwip_example ping set to 1 ping set to 1 ping set to 1 ping set to 1 ping set to 1 ping set to 1 ping set to 1 ping set to 1 ping set to 1 ping set to 1 ping set to 1 ping set to 1 ping set to 1
How this problem happens and how to fix it?
Thanks
