Hi Jiahui,
You debug in FR2355 Launchpad directly? Or use Launchpad to download your board?
If debug in Launchpad, please try several times, if it still doesn't work. MCU may be damaged.
If use Launchpad to download your board, please make sure the download is stable and short, and try again.
Thanks!
Best Regards
Johnson
