LPC551x flash by MCU boot utility(via USB-serial download mode) can't work.

Hi Sir

If we modify the bootloader VID/PID, and use MCU_boot utility to update the FW will fail.

Does the MCU_boot utility will check the VID/PID by USB?

What board evk are you using? What are the steps you are following? Are you using any SDK examples?

Have a good day

Our customer use their EVT board, we provid the method(how to change bootloader VID/PID).

Their platform is LPC5514.

Add MCU BOOT Utility version.

Does the tool will check the VID/PID?(I know that there are at least 3 types)?

Does the tool will check the VID/PID? yes, it can check it

If you modify the bootloader VID/PID, you need to adjust below args in \NXP-MCUBootUtility\src\targets\LPC55S16\bltargetconfig.py

romUsbVid = '0x1FC9' romUsbPid = '0x0022'
