Cannot flash LPC1549 firmware with USB on a Raspberry Pi

Hi All,

I have developped an application based on an LPC1549. My customer updates the firmware thanks to the USB connectivity my board provides.

On a Windows PC, it works fine ( I first erase firmware.bin and then I drag and trop the new binary).

My customer uses exclusively MACs. He has issues with the drag and drop method, but a command-line copy into the device works fine.

In production, he plans to perform the update thanks to a Raspberry Pi. Unfortunately neither methods work until now.

The command line he uses is the following:

rm /Volumes/CRP\ DISABLD/firmware.bin && cp -av M644_v02_05.bin /Volumes/CRP\ DISABLD/

Does someone now who to fix this issue ?

Thank you.

Regards,

Michel Kuenemann

I used openocd to flash lpcs using RPI and it worked well.

Hi all,

Thanks for your reply.

Finally it works with the following command:

dd bs=1024 conv=nocreat,notrunc if=/home/pi/new_version.bin of=/media/pi/CRP DISABLD/firmware.bin

For edu solution can be use each interface from openocd supported list. Stlinkv2 too.

Better way is use lpclink from NXP, which is compatible with lpcxpresso, openocd etc.

In my opinion you should use lpcxpresso at the beginning because its complete tool to flash lpcs and debug.
