Different behavior between J-link and I-Jet ?

Hello,

We noticed different behavior between J-Trace and I-Jet.

We use both with IAR.

It started on trying to trace code with stm32h743 eval board. we purchased j-trace for this issue, but it failed to trace code. Trying to do the same with I-Jet it succeeded without any issues.

The next thing we did is to move from eval board to our custom board.

The strange thing is that with I-Jet it does not go beyond

HAL_Init->HAL_InitTick->HAL_NVIC_EnableIRQ(TIM6_DAC_IRQn);

Immediately after thins function it gets continuous interrupts on TIM6, and does not get beyond HAL_Init.

(by the way, if I just program the application with I-Jet and attach to it after boot, everything works without issues, just the main steps with debugger get into problem).

Is there any idea why I-Jet behaves differently ?

Thank you,
