56800E Flash programmer, USB TAP and 56F8002

Gibson — Fri, 26 Feb 2010 01:02:28 GMT

Hi,

I'm currently using CodeWarrior 8.2.3 and USB TAP for flashing the 56F8002 on my application board. Now I want to pass it to the production guys with the 56800E Flash Programmer. My problem, the DSC stay in reset (or debug) mode after programming using the Flash Programmer. I disconnected the USB TAP and powerup the board but no change. I read the user guide three time but that didn't gave me a clue.

Is there a known problem with the 56F8002, USB TAP or the 56800E Flash Programmer?

Here is the details:

Hardware : T30 IBM think pad

Software : Wondows XP SP2, Code Warrior 8.2.3, 56800E Flash Programmer 1.1.1.1

56800E Flash Programmer:

Erasure Mode: unit

Leave device in debug mode > uncheck

Wait for device to power up > uncheck

Lock device after programming > uncheck

56800E Flash Programmer settings:

Device Configuration File: 568002_flash.cfg

JTAG Clock Speed: 800kHz

Verify Programmed WORDs only > uncheck

Use Remote CCS > uncheck

Port # 41475

Configure to use device > checked : CodeWarrior USB TAP

CCS Timeout : 5 seconds

When I hit the Prgram button, everything seem ok.

Programming details:

Using Configuration File: C:\Program Files\Freescale\CodeWarrior for DSC56800E v8.2.3\M56800E Support\initialization\568002_flash.cfg

Reading File C:\Project\output\sdm_pROM_xRAM.elf.S...

S-record ID: PROGRAM&DATA

Connecting to CCS...

Connected to local CCS server at port 41475

Configured to use CodeWarrior USB TAP

Placing the device into debug mode, please wait...

Flash unit #0 (P:0x000800-0x001FFF) Erased, and Checked Blank

Flash unit #0 (P:0x000800-0x001FFF) programmed, 547 words written

Flash unit #0 (P:0x000800-0x001FFF) Verification Passed CRC32 (0xc56c810d)

Exiting Debug Mode...

Thanks for your help.

OK, so let me make sure that I am clear on what the problem is. The board works great with the debugger, but once you try using the board in stand-alone mode (board uncabled from the development system, and powered up) it does not work? If that is the case, there is some critical device initialization that is being left out or the interrupt vector table is not being installed into the flash properly. The quickest way to determine where the problem lies is to find and example program that has a flash target (as well as a debug target). Select the flash target, build and download the program, and see if that works. If it does, then that confirms that the tools are not broken. If they are not broken, then try building your program with a flash target. (The Flash target settings may have been generated for you automatically if you used the New Project wizard to build your project.) Download that, and see if it works. If not, compare the program that does work with yours to spot the differences. Don't forget to to check the linker command files.

Hello Tom,

Sorry if I didn't answer earlier, I have been shifted on an other project for a couple of months. Now, I back on my 8002 project.

The board works great in the debugger and in stand-alone only if the flash is program with CW. If I use the 56800E Flash programmer, the board don't want to start. At first, I was suspecting the generation of the S-Record file but I follow the instruction in the user's guide.

Even if it's functional using CodeWarrior for programming the flash of the 56F8002, it's not pratical.

Thanks

Gib

It sounds like problem is not in the generation of an S-record. The suggestions in my previous post are still valid: there's something not being initialized in your code that the CodeWarrior debugger is handling for you. Is your build target set to one with flash? Can you generate an example program with the wizard, output an S-record file, then try that in the Flash Programmer?

As you suggested, I made some test with a simple program and the same thing happen. After Flash programmer exit from debug mode, the "Run/Pause" LED on the USB TAP is green and the board seem to be in reset. I tried to flash the .efl file instead of the S-Record file. The simple program start ok. My application's program start to but is missing some part. Basicaly at power-up, the board suppose to send a small srting on the SCI and then activate some output in reaction to an input.

To resume:

With CodeWorrior : Program ok, start ok, run ok

With Flash programmer (S-Record) : Program ?, start no, run no

With Flash programmer (.efl) : Program ?, start ok, run half (missing string)

I must find what is the missing initialization. When I use Processor Expert, there is no real target selection.
