Hi,
I checked with imxrt1064 evk schematic ENET_INT and ENET_RST connected to jtag.
Imported tcpecho echo example code this two pins controlled manually by using GPIO.
Compulsory we needs to handle these two pins ?
(or)
Can we connect two pull up resistor these two pins with out handling gpio ?
Thanks & Regards

Solved! Go to Solution.
Hello,
>>If we change these two pins value how jtag working without disconnecting from debugger ?
ENET_INT/ ENET_RST and JTAG_TDO/JTAG_TDI can use at the same time.
And for the code please remove GPIO_WritePinOutput(GPIO1, 10, 1); delay() time please refer to KSZ8081RNB file.
Hello.
By default i.MX RT1050 uses the SWD interface for debugging, applyingonly JTAG_TMS (as SWD_DIO) and JTAG_TCK (as SWD_CLK) signals.This allows to use other JTAG related pins for different functionality.
For ENET_INT please use the GPIO.
For ENET_RST can use pull up resistor for it.
Have a nice day.
Hi,
IMX RT 1064 evk schematic
ENET_INT connected to JTAG_TDO
ENET_RST connected to JTAG_TDI
If we change these two pins value how jtag working without disconnecting from debugger ?
This code i took from tcpecho example
GPIO_PinInit(GPIO1, 9, &gpio_config);
GPIO_PinInit(GPIO1, 10, &gpio_config);
/* pull up the ENET_INT before RESET. */
GPIO_WritePinOutput(GPIO1, 10, 1);
GPIO_WritePinOutput(GPIO1, 9, 0);
delay();
GPIO_WritePinOutput(GPIO1, 9, 1);
Can you give code example for handling gpio (For ENET_INT please use the GPIO) ?
Thanks & Regards

Hi fangfang,
Thank you.
