STM32F411 JTAG setting bug

Hello,

I use CubeMx (6.6.1), STM32F411CCUx

CubeMx causes a problem when 'PB4' pin and JTAG (4 pin) are used together.

If JTAG (4pin) is set in CubeMx, PB4 is not used.

If i set something in PB4, JTAG is released.

In the datasheet, PB4 and debug have nothing to do with it.

What should I do...

Thanks for reading.

It is a long standing errata that JNTRST can not be used otherwise when JTAG is needed.

But will the hardware issue get fixed sometimes?
