jlink flash timeout

A jlink flash timeout occurs when the J-Link debugger is unable to communicate with the target device during a flash programming operation within the specified time limit. This can happen due to various reasons such as incorrect device configuration settings, faulty hardware connections, or issues with the flash memory itself. To resolve this issue, you can try reducing the flash programming speed or increasing the timeout value. You can also check the hardware connections and make sure that the target device is properly powered and configured. Additionally, you can try updating the J-Link firmware to ensure compatibility with the target device.
