Zybo Z7-20 JTAG run not working but debug works

[AJ25000]

Hi!

I'm new to SoC development. I bought a Zybo z7-20 board to learn developping HW + SW. My first projects with this board (HW + SW) were working well (with run mode in sdk 2017.4 and vitis 2022.1), but 1 week ago, it stopped working. I have no idea why, i didn't change anything in my hardware nor in my soft...

Can anyone help?

Hi @AJ25000

What issues do you seem to be running into? Are SDK or Vitis throwing any particular error messages?

Thanks,

Arthur

Hi @artvvb

There are no errors when running the program, but nothing happens on the board. I've made a simple program to light up a LED, it works in debug mode, but not in run mode.

Hi  @artvvbi have some good news.

I think my Zybo Z7-20 have a problem with the PS part. 

I've made a design with a custom AXI4-Lite PWM module (i set values to a register to define the duty cycle and the frequency). It is working in run mode BUT i have to wait about 10 min after clicking "Run" to see the LED blinking on the board.

 

Any ideas?

Did you simulate?

Sounds like something like a counter is not properly initialized and it takes about 10 minutes for it to roll over.

Oh!!!!! Maybe i haven’t initialized the 2 counters in my design!!! Have to check for this. Thank you!
