Compiler/EK-TM4C123GXL: Can't access ROM_ functions

William Herschel

Part Number: EK-TM4C123GXL

Tool/software: TI C/C++ Compiler

Hello,

The ‘hello’ example has #include "driverlib/rom.h" and references to ROM_ functions are resolved. My project has the same #include statement but any reference to ROM_ functions gives unresolved symbols. It’s because the ROM_ functions are greyed out in the driverlib in my project, but not in the hello project. I don’t know why they are grey. Is there a way of un-greying them? (It's the same part for both projects).

Thanks

    I have answered my own question in the time delay between continents. After much anguish and looking at other posts it appears that the Symbol TARGET_IS_TM4C123_RB1 was missing in the Predefined Symbols of the Properties page. But anyway this forum is invaluable. Many thanks.

    Hello,

    Bit of a 'senior moment or distraction' - perhaps?     (Young staff here suspects 'comments/postings' was intended.)

    And made more so - by your kindness & effort in clearly describing & then reporting your 'FIX!'   (thus closing the loop - to the benefit of MANY!)

    It should be noted that such 'Time Delay between Continents' has (just) become (very) REAL (i.e. quantified) - with Qantas announcing, 'NON-STOP, sub-20 hour flights, NYC to Sydney!'

    Details: Brand-new Boeing 787-9 flew non-stop from New York to Sydney in 19 hours and 16 minutes.    The 787-9 departed JFK (NYC 21:27 Friday night) ... landed at Sydney 19 hours and 16 minutes later  (SYD 07:43 local time on Sunday morning!)    {having crossed the International Date Line.    Proves quite an ordeal - being entombed w/in a metal tube - for so long... we are told that the cb1 firm's 'bathroom counters' over-flowed!    (better they than the ceramic structures!) ... limitations likely imposed by our 3 digit (Li-Ion Battery V. measure) being 'Pressed into Count Service...'}

    Hello William,

    Glad you were able to find the solution through the Forums, sorry that we were not able to assist sooner directly.

    Hello Ralph,

    A benefit of the time difference is that the well-known syndrome of stepping back for a moment and then seeing clearly now (as Johnny Nash sang) solves many problems.

    All the best

    Hello cb1_mobile,

    You could be right with your first remark. The last time I was in Sydney was thirty years ago and I was writing a program to shut down a VAX 11/780 computer if the air conditioning failed. The room could get to 50C when it did.

    Best wishes

    William
