RCC Conflict with Debug JTEG 4 pin

[vchau.2]

Hi All,

I'm using RCC both the crystals on PC14- 15 and PH0-1 and I want to use JTEG TRACE with 4 bit synchronization but when ever JTEG TRACE enable RCC showing warning  "status: Parity disbale conflict with debug jteg 4 pin"

Kindly let me know what the mean of this and how to solve this.

thanks

Hi,

No problem on H743ZIT :

If you have small case, maybe not enough pins to do this 4bit jtag...

Solution: take 144pin case (Z) , or try, what size is minimum for these functions at same time.

Pin availability isn't a issue, I'm using STM32H755 BGA package, infect there is no connection between crystal oscillator pin and JTEG TRACE pins

Ok, you didnt say the type before ... 

First clear the (red) problem in your clock configuration, then look, what message it shows for 4pin jtag...

(Using same pins should not be the problem then.)

btw Why you need this 4pin jtag...?
