LPC54605 firmware update by MSC failed

37139023 — Wed, 09 Dec 2020 06:01:52 GMT

I am working with a LPC54605 which can accept firmware updates using MSC mode. but, when I drag and drop my firmware.bin to LPC54605 u disk,then reset the board,it do not run.

But when I use Jlink to download the fireware,it works. why? Is there anything I didn't do right?

Hello ,

What about your firmware?

Your project is probably configured semihosting printf : See section 15.4, "What is Semihosting?" (and in particular section 16.4.5 Semihosted printf and Debugging"), of the MCUXpresso IDE User Guide for details. For example printf to console, not UART.

Regards,

Alice

Hi，

Thank you for your reply。

Firmware is just a simple flash example. Does firmware need safe mode firmware? How to make it safe mode?

Hi Alice,

I'm having the same problem on lpc54616 . using the same binary over SWD and USB MSC leads to different behavior, SWD works while MSC doesn't.

The procedure i'm folling for the update is the following (in linux OS

1) boot the board with ISP pins set for MSC mode

2) mount the uC partition

3) delete the file "firmware.bin"

4) copy the binary file changing the name to firmware.bin

5) unmount the partition (tried also without unmouinting)

6) power cycle.

Are these the right steps ?

Thanks and best regards,

Filippo

Have you created the image checksum?

Hi @converse,

Indeed, the binary creation and checksum procedure was commented out in the build step.

I've added it but still no luck, the FW still doesn't work after the update.

Please advice? I'm out of ideas.

Best regards,

Filippo

I have an update. I first erased the flash via SWD (also blank checked), then restarted the system in ISP and updated the binary image. I've restarted the system and performed a verify against the same binary and here the output:

for some reason the flash is still blank! do I miss something in the procedure?

I found what was wrong.

In the update procedure, since I had no control over the reset pin, i was power cycling the board and this was leading to FW corruption.

I wired a reset button first and a GPIO later and this solved the issue, just resetting the uC instead of powercycling the system.

Thanks for the help.

Best regards,

Filippo
