Target is not responding, retrying... (Nucleo L073RZ board)

[CAben.1]

Hello Everyone,

II'm currently working with my Nucleo L073RZ board and so far my program built successfully but i cant upload it. Nonetheless, other programs are still able to run well on the board. I dont understand what i am doing wrong. I have read other responses to similar questions but i still cant find a solution. Please I will be glad to get some help/ideas on how to solve this. Thank you.

Best Regards!

Hello @CAben.1​ ,

Maybe you should check the SWD connector.

Did you try ST-Link Utility to solve this problem?

Try with the ST-Link Utility and "connect under reset" mode, then "full chip erase" option.

I'll be waiting for your feedback.

Hi i have the same issue and I tried st link utility and did not work.

You likely have a SIMILAR issue.

Perhaps looks at what you did to the target IC to block debug access, say disabled SWD/JTAD operation, reconfigured the pins the debugger uses (PA13, PA14, PB3, etc), or that you powered-off the circuitry that needs to be running for this to work. ie put the device in Low Power / Standby modes?

Pull BOOT0 pin HIGH so YOUR CODE doesn't run and break access.

The ST-LINK Utilities have been deprecated for many years, migration to STM32 Cube Programmer is STRONGLY recommended.

i tried stm32 cube programmer too. now to don't get the error "Target is not responding, retrying..." . I get "Download verified successfully". but when I resume the code its not running
