EKLM4F120XL

hello guys,

I am using Stellaris EKLM4F120XL evaluation kit which is almost equal to Tiva board.At first I used to run any code and it used debug successfully with IAR Embedded workbench.After I ran qs-rgb programme given in stellarisware.It also ran successfully.but after that i ran led blinking programming of my own there was error in downloading:

 Verify error at address 0x000000E2, target byte: 0x00, byte in file: 0xD8

Verify error at address 0x000000E3, target byte: 0x00, byte in file: 0xFF

I tried to erase flash using LMFLASH Programmer.But it still doesn't work.And there was increment in number of errors.

There is any way i can stop this??

    Hi Vishal,

         Post that blinking program that you made, so others can review it.

         Try the LM Flash Programmer Debug Port Unlock Utility (select Blizzard Class). See, post below for further info.

         JTAG Communication Failures

    Vishal,

    Can you post the entire project here? One of us can take a look at it and suggest a few pointers.

    Regards,

    Ok here i am posting.My programme is very simple.I have used simple pointers to turn on all the bits of RGB LED.

    int main() { *((unsigned int *)0x400FE608U) = 0x20U; *((unsigned int *)0x40025400U) = 0x0EU; *((unsigned int *)0x4002551CU) = 0x0EU; *((unsigned int *)0x400253FCU) = 0x02U; *((unsigned int *)0x400253FCU) = 0x04U; *((unsigned int *)0x400253FCU) = 0x08U; return 0; }

    As you can see it is very basic code.No complications

    Now here the errors after formatting flash:

    Inclusion of each/every, "Verify error" may have been bit much - n'est pas, mon ami?  (beyond 1st 100 or so - eyes teared...)

    If you say so - then direct register writes into 0x4002.xxxx, 0x400F.xxxx - is, "very basic, no complications."  (appears the equally, basic use of "comments," clarifying your code objectives - escaped concern.)  "Usual suspects" when JTAG becomes disrupted are a mismatch between board's xtal value & value chosen via your SW, and or JTAG pins (PC0-PC3 repurposed - deliberately or by accident) - yet results in board "lock-out."

    You spoke about Flash Erasing - which is not the "Unlock Procedure" - found under Utilities/other (tick Blizzard) and follow all of the usage guidelines.  (i.e. pay attention to reset instruction)

    That JTAG speed @ 500KHz seems high - and had you intended to switch to AHB (fast) bus?

    We also run IAR but via J-Link - note 100KHz speed in our successful exchange, below.  (and via SWD)

    Dear  ,

    I am a beginner.I don't know much about MCU stuff.I am new to this field.I don't have knowledge of JTAG much.Can you explain in detail how to solve this?

    Well yes - but Ms Cozart has already done that - generously adopting some few tips/guides from this reporter.

    http://e2e.ti.com/support/microcontrollers/stellaris_arm/f/471/t/143216.aspx

    Your posted code - using both Direct Register rather than StellarisWare & targeting 0x4002.xxxx & 0x400F.xxxx may not be especially wise for a beginner.  Great attention to detail must be supplied - thus a very thorough read & comprehension of those critical registers is mandated - prior to any transaction.  Even a single miscue - inflicted upon one lone register bit - can produce the misfortune you now suffer...

    Thanks for the help.I will try everything to get out of this mess.

    I think I have got the problem.

    The board is working fine with stellarisware projects.In all of those project files,"Startup_ewarm" is common.I read it and it makes some changes in the board to enable IAR extension.And had some code in it.I didn't get the code much.And after if i try to run my code then debugger shows the errors.But if i again load the stellarisware project of qs-rgb,it works fine.

    Here i am sending you a link which are the files of qs-rgb project of stellarisware:

    https://drive.google.com/folderview?id=0B4XnLYjho101eGFhMlJMcGttNTQ&usp=sharing

    check all "startup_ewarm" and ewarm stuuf.If anyone can help in this.
