pins used to program target device stlink

Post by dev » Fri Sep 29, 2017 12:33 pm

Hi,
I was looking into Stlink schematic. i found little bit confusing. Pin names make me confused like T_JTCK, STM_JTCK, TCK, STM_JTCK and Same pins were for TMS.

Controller is also having different pins for that. I thought they are same. but they are not.

i think PA13 and PA14 will be used for programming controller used in stlink.

I am trying to figure out which pins are used as SWDIO and SWDCLK to program target device.

[STLink - T_JTMS] PB14 --> PA13 [JTMS/SWDIO]
[STLink - T_JTCK] PB13 --> PA14 [JTCK/SWDCLK]

Code: Select all

ST-Link       |     Target
-----------------------------------
PB14 (T_JTMS) | PA13 (JTMS/SWDIO)
PB13 (T_JTCK) | PA14 (JTCK/SWDCLK)
