Production programming LPC5504

Kabao — Wed, 23 Mar 2022 07:12:08 GMT

Hello.

I have lot of boards with LPC5504, and I need to set on foot automatic programming of them, so I need some hardware tool that connected to MCU, and software, that can be built in my software. So, software can be:

library
console application
GUI application that can receive all necessary parameters vis command line or config file
any other type that can be called and perform erase-program-verify without involving user interaction

I tryed to use MCU-Link as hardware, but I can't find appropreate software (openocd don't support LPC5504, MCUXpresso have't tools that I need). J-Link can be used for that, but it much more expencive than MCU-Link.

So, my question: is here any software solutions to use MCU-Link or some other cheap hardware for stream programming of boards?

Hi,

The Bootloader code is integrated into the ROM of LPC5504, I think you can use use bootloader to program the LPC5504 on-chip flash.

The PIO0_29 and PIO0_30 are Uart pins, you can connect the two pins to a USB-UART board from third party to do the work.

On the PC, you can use blhost command.

This is blhost command instruction UG.

You can download the SDK from the link:

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

After you unzip the package, pls refer to the directory for the blhost.exe

....\SDK_2_10_1_LPCXpresso55S06\middleware\tfm\tf-m\platform\ext\target\nxp\common\secure_boot\tools

Another tools is Flashmagic, you can download application code via both SWD and in ISP mode.

Hope it can help you
