MSP432E401Y: Creating a bootloader that utilizes a HTTP post request to upload file

John Grant

Part Number: MSP432E401Y

I'm currently using lwIP to host a HTTP server for the MSP432E401Y. I've successfully done updates through BSLScripter and the ethernet port, however, I have run into an issue where users of the device may not have access to changing firewall permissions in order to allow the update to work. This is since the BSLScripter uses TFTP to transfer the TI TXT file over, and TFTP is often not allowed without administrator access to the computer doing the update.

Therefore, since I can host a website and can show a form to submit a file, I am looking into simply transferring the file through an HTTP post request. This would then be handled by the processor and copied over to flash.

I'm having trouble finding any information showing the detail of accomplishing this though. Has anyone here attempted this? Is it even possible?

    Hello John,

    I'm sure you are aware, but here is the MSP432E4 BSL User's Guide.  

    Unfortunately, I'm also not sure how to accomplish this.  You would need to customize the BSL as you mentioned but I don't have any specific guidance I can provide here.  I did some searching to see if I could find any other conversations from the community attempting this type of thing in the past and I've come up empty. 

    I'll leave the thread open in hopes that maybe someone from the community has looked into this type of configuration before.  

    Thanks,

    JD
