CCS/TMS570LS3137: File does not match the target endianness, not loaded.

Part Number: TMS570LS3137
Other Parts Discussed in Thread: RM57L843,

Tool/software: Code Composer Studio

Code Composer Studio Version: 8.2.0.00007

I've developed an application which I've been testing on an RM57L HDK for months. But when I try to debug my application on another copy of the HDK I get the following error message:

CortexR4: GEL Output: Memory Map Setup for Flash @ Address 0x0CortexR4: GEL: File: xxx.out Does not match the target endianness, not loaded. Check project build options and target configuration file (ccxml).

To be clear, this error doesn't occur when I debug on another seemingly identical HDK. I've verified that the Hercules Safety MCU Demos do run properly with the new HDK. What am I doing wrong?

    Hi Hugh,

    The RM57L is little endian by default, correct? Is there any way to change the endianness on the device or is that fixed? Assume it is fixed, it may be some strange configuration issue.

    Are you using the same environment (PC) when switching between the various HDKs - meaning the only thing that is changed is the HDK while everything else is the same?

    Thanks

    My understanding is that the processor supports "the word-invariant big-endian [BE32] format."  

    Yes, identical environment. The only thing that changes is the HDK.

    Are you using the TMS570LS3137? You mentioned the RM57L HDK, which has an RM57L843 - a Cortex-R5F based device

    Ki-Soo,

    Wow, am I an idiot! You are absolutely right. The RM57L HDK has the RM57L843 device, whereas the TMS570LS31x HDK (the one I've been using for a while) has the TMS570LS3137, of course. I was fooled by the fact that the two boards look identical. Thanks for pointing this out to me.

    Glad to hear you figured out the issue. Yes the fact that the boards look nearly identical is certainly confusing. I wish they was an easier way to identify the device other than trying to read the tiny (and hard to read) lettering on the device packaging itself!
