The LPC54S018 disables SWD once Secure Boot is turned on. In other words, after I start the secure boot, if I want to download the new correctly encrypted image, do I have to enter the ISP mode to download?
I only know that the flash magic tool can be used to download images in ISP mode. I read the signature successfully, but failed to use it to download a plain image. The error it returns is as follows. using flash magic to download a image in ISP mode failedAre there other recommended tools that can be downloaded in ISP mode?
