Cannot debug (stuck in BadRomLink exception) CC2650 SimpleBLEMulti example in IAR.

Other Parts Discussed in Thread: CC2640

In IAR EW ARm 7.40, I am trying to debug and step through the SimpleBLEMulti example on a SmartRF06 eval board using the CC2650-7ID 1.2 module.

It builds and downloads, but when I enter the debugger I am permanently stuck in the error handler:


ti_sysbios_rom_cortexm_cc26xx_CC26xx_badRomLink__E:

0x188e: 0xe7fe B.N ti_sysbios_rom_cortexm_cc26xx_CC26xx_badRomLink__E; 0x188e

This suggests the there must be something wrong with the builder or linker settings, but I can't figure it out. Anyone know what's wrong?

Additionally, I don't know if this is related, but there was an initial error where if I try to debug, an error pops up: "the debugging session could not be started. Either the debugger initialization failed or else the file..." The extra image was not built, and I don't know how to change to options to build it. I went into Project-->Options-->Debugger-->Images and unchecked "Download Extra Image". Does anyone think this is related, or can I leave it undownloaded?

    Hi Cindy,

    It looks like there is something wrong in your build system. What version of our stack are you using? v2.0 or v2.1?
    I just built and loaded the project using IAR 7.40.2.

    Here are some suggestions for fixing your problem:
    - Try deleting <$BLE_STACK_INSTALL>\Projects\ble\SimpleBLEMulti\CC26xx\IAR\Application\CC2640\configPkg and <$BLE_STACK_INSTALL>\Projects\ble\SimpleBLEMulti\CC26xx\IAR\Config\src, where BLE_STACK_INSTALL is the location you installed your BLE stack.
    - Erase the flash of your dev board using SmartRF Flash Programmer 2
    - Rebuild the project in IAR and attempt to load again, remember that the Stack should be loaded before the app.

    Thank you Sean,

    The problem is likely that I didn't load the stack first (silly me). However, I am now getting build errors trying to build the stack (v2.1). I tried a new install of the v2.1 stack and SimpleBLEMulti patch, but the same thing still happens. Does anyone have an idea what's wrong? Here's the build log:

    Sorry to play give a mouse a cookie, but do you know what is the default program that was loaded onto the SmartRF06 Eval Board and CC2650EM module? And where to get it? I overwrote it when I downloaded the SimpleBLEMulti app.

    Cindy,

    I am not sure exactly what application the boards ship with but my guess is SimpleBLEPeripheral. The .hex image for this project (and many others) can be found in C:\ti\simplelink\ble_cc26xx_2_01_00_44423\Accessories\HexFiles. Use SmartRF Flash Programmer 2 to re-flash the board.

    Also to my knowledge, the Multi demo is not yet ported to v2.1, but we are working on it now.

    Thanks Sean.

    I found the default program, which doesn't have the source. The HEX is available in this thread:

    Thank you Sean,

    I tried the Multi demo with the 2.0 Stack and everything works fine now.
