5213 - "Application record checksum failed" message @ boot

[Ridgeglider]

One of my students has built a PCB to accept a 5213 module.

He's switched the monitor to boot to Com1 instead of the default Com0. With the Mod5213 on his new PCB, he has downloaded known-good code to the monitor via MTTTY and the "fla" command. He gets the message below at boot:

Waiting 5sec(s) to start 'A' to abort
Application record checksum failed.

Toast? Suggestions? I told him to try downloading to the module with it attached to a standard 5213 Dev board. Not sure yet how he made out. Have not run across this error message before.

tell him to go to C:\nburn\MOD5213\original folder and download the "MOD5213FApp_APP.s19" file into it. this way you know you have a valid file for it.
dont forget to remove and restore power to it, before doing so. this sometimes resolves other issues that a simple reset does not.

Another possibility is that the application download had errors. The error you show means the application (not the boot monitor) has a cksum failure. You need to have flow control enabled if downloading to the 5213 at 115,200. You could either enable the flow control, or try downloading at a lower speed, like 9600.

I am ridegliders student, the one getting the "record checksum failed" message.

Still trying to establish comms with a newly installed copy of Eclipse.....

Now flashing Netburner's code (MOD5213_A2D_APP) through MTTY is working fine but I can't load the very same example code through Eclipse. When I try I get the same "record checksum failed" message.

Any suggestions?

What did you do in Mttty that corrected the problem?

I went back into the monitor's setup dialog and switched the boot port from 1 to 0. Then flash loaded my code through UART0.
