firmware update using a UART for the LPC21xx device and LPC1549 device

Dear support,

Can you advise me if you do any packages where i can do a firmware update or download some firmware through the RS232 port on a linux system.

I have been using a product called flash magic but this doesn't seem to friendly with linux.

Any suggestions would be appreciated.

Thanks

Andrew

Lpcscrypt won't help you as it for LPC18/43 parts.

you might try this open source utility - mxil

Hello Andrew,

You can try the utility that Con Verse is saying. Another option is to develop your own utility, you can use the next application note https://www.nxp.com/docs/en/application-note/AN11229.pdf as a guide to see how you need to send the data through RS232.

Regards,

Victor.
