NUCLEO H743ZI Unable to match requested speed 8000 kHz, using 4000 kHz.

Posted by suhoze on 2019-08-04 13:12

NUCLEO F429ZI works without Stlink adapter speed issue.
Project on NUCLEO H743ZI has trouble with Stlink adapter speed below.
What can I do to fix it?

Having the exact same issue with an STM32L0538-DISC0. did you manage to find a fix for it?

No. I couldn’t.
I am coding on F429 instead of H743.
I guess I have to wait for fetch from ST. I had same issue on F429 before. After some fetch on SWorkbench, no problem with F429.

Goto Run -> Run Configuration -> Select ‘project name’ Debug -> Debugger -> Under Configuration Script Click Show generator options -> General Option -> Connection Setup -> Set Frequency Less than 4000KHz.
