Is there a PC app for LPC55xx ROM Bootloader?

PE_IDR — Wed, 21 Dec 2022 20:38:50 GMT

The LPC55xx processors have an internal boot loader in ROM. Is there an existing PC application from NXP for that bootloader? I see that the specification in the User Manual has the information needed to create one, I'm just trying to verify that my layout works prior to investing in building my own ISP.

Hi,

On the PC side, you can use the blhost.exe tools to communicate with the bootloader in ISP mode.

After you download SDK based on LPC55xx, you can go to the directory for the blhost.exe

for LPC55S36:

C:\DriveE\LPC_SDK_MCUExpresso\SDK_2_10_2_LPCXpresso55S36\middleware\tfm\tf-m\platform\ext\target\nxp\common\secure_boot\tools

You can download SDK package from the link:

https://www.nxp.com/design/software/development-software/mcuxpresso-software-and-tools-/mcuxpresso-software-development-kit-sdk:MCUXpresso-SDK

I attach UM of blhost tools

Hope it can help you
