Hi, I'm trying to load official .s19 demo to my MCF51JM128 but only white screen appears. I can't use BDM cable and my SW5 settings are all right. How to fix it?

Hi Piotr,

Sorry for your difficulty.

When you plug in USB cable, it is enumerating as USB MSD?  Do you see "Bootloader mode: waiting for S19 file..." displayed on LCD?

If yes to both please try using my "precompiled S19" files to test your display.

Here is my sw1 configuration for reference:

Hi!

I have same problem. Your demos work great, but when I try to compile the latest demo from eGUIs package only white screen show up. I use CW 10.6. May I ask you to show us your source files (1 project would be enough to compare diffrences)? .

Thank you! This is very helpful, but only to regain bootloader. I want to design my own application using MCF51JM128, but as mentioned earlier Official Demo provided by CW10 results only in white screen ;/

Hi Piotr,

I had to dust off some old old project files to find something that compiles with CW10.6 and is targeted for working with the TWR-LCD bootloader on the JM128.

Attached is ZIP.

Open the ",project" in the following path:

TWR-LCD Demo Projects\CW MCU 10\HelloWorld_MCF51JM_SPI_BL

Before you try to clean and build you can try the S19 file in the sub folder with respect to the above project path:

MCF51JM128_Internal_Flash\HelloWorld_MCF51JM_SPI_BL.elf.S19

Hope this helps.

Regards,

David
