MCUxpresso GUI Flash Tool program KW38 over Flas size 0x40000 issue

Dear

I want to use GUI Flash Tool of MCUXpresso to programming attach file, but I find it can't work.

But if I use IAR to programming attached file, it seems it will be programming successful.

For example, I use FRDM-KW38 EVB with IAR to programming, the UART console will show

The LED4 will be twinkle white, when I press SW3, LED4 turns to flashing red.

Then I check the Flash memory address, the Flash address 0x40000 will have data.

Then I use GUI Flash Tool of MCUXpresso(v11.5.0 [Build 7232] [2022-01-11]) to programming same file, it will show "Unable to perform operation! Command failed with exit code 1)

Then I unplugged the USB, plugged it back in, and found that LED1 is always on red, I looked at the wiring schematic and confirmed that this should be the Reset pin that is always grounded.

Then I set Attach only and Reset on Connect in Debug Configurations to check memory.

Then I found that only burned to 0x3FFFF, more than 0x40000 are not properly program.

This is the binary file attached.
Anything over 0x40000 has not been properly burned by the GUI Flash tool.

Is it impossible to show more than 0x40000 content that is burned by MCUXpresso?

Thanks,

Kris

Dear Eduardo

I've try use J-Link with MCUXpresso 11.5 can be successfully burned.

And the SDK version is SDK_2_6_212_FRDM-KW38.

Hi,

I apologize for my late response.

Could you please help me with more details about which version of the SDK are you using?

Would it be possible to test the Flash Tool by using a binary file from another example project? Just to confirm this behavior.

The size of the binary file that you attached caught my attention. Is your project based on the shell example from the SDK? Could you please help me with more details about what modifications you made to the base source code?

Regards,
Eduardo.
