Ethernet and SWD on RT1064

[ThomasSC]

Hi,

i want to use one MII-Ethernet and the SWD for debugging.

Is it correct, that i have to use the Ethernet2 because SWD and MII0 share the same pins?

thanks,

Thomas

Hi,

for the RT1064 i found this pinout for SWD and ENET:

Instance	Port	Pad
SWD	SWD_DIO	GPIO_AD_B0_06
	SWD_CLK	GPIO_AD_B0_07
ENET	ENET_RX_CLK	GPIO_AD_B0_06
	ENET_TX_ER	GPIO_AD_B0_07

ENET_RX_CLK and ENET_TX_ER are used by a full MII-Interface PHY (e.g. KSZ8863MLL).

Is it correct, that SWD works with RMII-Interface on ENET or (R)MII-Interface on ENET2 but not with MII-Interface on ENET?

Thanks

Thomas

Hi,
Thanks for your reply and clarification.
1) Is it correct, that SWD works with RMII-Interface on ENET or (R)MII-Interface on ENET2 but not with MII-Interface on ENET?
-- Yes, if you need to use debug tool to connect the SWD interface for debugging.
Have a great day,
