MSP432E401Y: [ERROR_MESSAGE]There is invalid TFTP Read Request in the packet received!

Part Number: MSP432E401Y
Other Parts Discussed in Thread: UNIFLASH

This has been asked here before a few times, but no resolution has been given.

I am trying to follow the instructions exactly as given here (MSP432E4 Boot Loader (ti.com)) to use the Bootloader and an Ethernet link to update the application image on an MSP432E401Y evaluation board, but I am getting the above error message when using the BSL-Scripter tool (Task 4 - Step 6):

MAC address of the board is correct, as is IP number of the server (laptop).

I can see in Wireshark that the board sends out a BOOTP request but the BSL Scripter never responds to it.

Firewall on the server (Windows 10 laptop) is off.

Please let me know how to fix this issue.

It's been a while, but I recall that BSL-Scripter reports a timeout as a "bad packet" (which isn't the same thing at all).

I suspect the relevant problem is that BSL-Scripter isn't getting its BOOTP response to the MSP432E board, for whatever reason. Do you maybe have more than one firewall? (AVG, e.g., has its own separate firewall.)

Hi Steffen Reymann,

I'm having the same problem as you.
Did you manage to find a solution to this problem?

Hi Nuno, make sure the MSP flash memory is completely empty before starting the update process. That seemed to solve the issue.

Hi Steffen Reymann,

Could you please give me details on how to clear the MCU memory? I wasn't able to found this option in CCS when I was following the TI tutorial.

Hi Nuno, I'm not sure it's possible via CCS. You can use Uniflash: under "Settings & Utilities" you have the option "Erase Entire Flash".

In CCS, right-click your project and click Properties > Debug > MSP432E4 Flash Settings. The default setting should be "Erase main memory only".

Hi Steffen Reymann and James Evans,

Thank you for your inputs.

Despite this I was unable to overcome my problem even after erase entire flash memory.

I Will try on a different PC on next weeks.
