And also note that ``` Info: Unable to match requested speed 8000 kHz, using 4000 kHz ``` is just an informational message, not error at all!
--- **[tickets:#461] stm32f4x.cfg Requested Speed Too High** **Status:** new **Milestone:** 0.12.0 **Created:** Fri Oct 17, 2025 04:15 PM UTC by Antonio Chiu **Last Updated:** Sat Nov 01, 2025 08:29 AM UTC **Owner:** nobody **Attachments:** - [stm32f4x.cfg Requested Speed Too High.rtf](https://sourceforge.net/p/openocd/tickets/461/attachment/stm32f4x.cfg%20Requested%20Speed%20Too%20High.rtf) (50.0 kB; application/msword) Tested on NUCLEO-F401RE (stm32f401re). It has the slowest Fcpu (adapter speed) in the STM32F4 series. It seems that the original adapter speed for reset-init and reset-start is too high for my board. I've reduced the speed to get rid of the errors. Technically this should work on all other STM32F4 boards as they all have higher Fcpu. --- Sent from sourceforge.net because [email protected] is subscribed to https://sourceforge.net/p/openocd/tickets/ To unsubscribe from further messages, a project admin can change settings at https://sourceforge.net/p/openocd/admin/tickets/options.
