FRDM-K64F Silicon Errata for PK20DX128VFM5 & MK20DX128VFM5

[muthurajm]

Hi All,

Need of Silicon Errata Sheet for these microcontrollers.....

PK20DX128VFM5(Pre-Qualified) & MK20DX128VFM5(Market Qualified)

Prequalified version MCU assembled FRDM-K64F(2 NOs-REV C) is Not working for any code that has been locally builded.

The same builded file is working fine with Market qualified MCU assembled FRDM-K64F(1 NO-REV E)

But sample code from Demo package provided by Freescale is working fine on Both REVC and REV E Boards.

Regards,

Muthuraj

Hi Muthuraj,

The second line of the mask print is the silicon number, then you can find the corresponding errata data of the silicon version through the link as below.

Hope it helps.

Hi Jeremyzhou,

Thanks a lot for your help.....

If possible Need your help on debugging the Non working FRDMK64  Rev C Boards with Prequalified OPEN SDA Controller IC.

Issue summary:

1.whatever BIN am building locally is not working on REV C Boards and working fine with REV E Board.

2. Demo package sample BIN is working fine on REV C board also.

Kindly Help:)

Hi Muthuraj,

I didn't have the Rev C board on hand. The issue seems very weird.

And I'd like to confirm with you about whether the BIN can works on Rev C board or not after programmed by JlNK tool without using the Open SDA interface.
Have a great day,

Hi Jeremyzhou,

Thanks a lot....Kindly share the details about this Jink tool like where I can get it & how to use it.

If debugger is needed where I can get that, Because I had searched couldn't find anything relevant to that.

Great DAY:)

Hi Jeremyzhou,

Thanks A lot.....

JLINK tool I will check

Can you please send me some locally builded BIN file for simple LED Blinking using your compiler.

Need Clarification:

1.what might be the difference between the Demo package sample code BIN and locally builded BIN for same application.

2.Shall we replace the Open SDA Microcontroller and after replacement do we need to flash any firmware to make it work as open SDA.

Kindly Help :smileyhappy:

Hi Muthuraj,

You can figure out the way to program the bootloader and firmware after have a brief look through the document whose link has been shared as below.

I've also attached a led_demo file and please check it.

Hi Jeremyzhou,

Thanks for your support:)

Our board(Open SDA V2) wont support this SREC format Kindly provide the same in BINARY format.

Hi Jeremyzhou,

Thanks for your help:)

Same response from the both REV C boards.

Completely Idle!!!

Will check on the REV E board and Let you know, Thanks.

Muthuraj M

[muthurajm]

Hi Jeremyzhou,

Flashed the same code in REV E board.

GREEN LED is blinking....Working fine....

Can you suggest something else to debug this issue.

Regards,

Muthuraj M

[jeremyzhou]

Hi Muthuraj M,

The attached BIN file is generated from the hello_world demo from the KSDK_1.2.0.

And I'd like to suggest that you can debug this demo both on REV C and REV E board to figure out the difference of code execute process such as several  clock sources configuration.

You can go to download the KSDK_1.2.0 through the link as below.

Dear Jeremyzhou,

Thanks.....Already we had tried.

Both the REV C boards are Idle for the BIN file that you had provided.(This is the same thing happening even if we using our compiler and building the code)

But in REV E board GREEN Led is blinking for the same BIN that you had provided......so what might be the difference.

Hi Muthraj M,

I think you misunderstood my opinion, I know the BIN file failed on REV C board.

However when you debug the hello_world demo that I mentioned in last reply, by using step debug that the debug tool supports you will figure out which code line executes, then causes the MCU hangs.

After you find it, then the issue will be clear.

Dear Jeremyzhou,

Thanks a lot......

In the Rev C boards (2Nos) while executing the Program through the debugger it Jumps directly to "RTOS scheduler idle task" and executing the same infinitely.

But the same is not happening with Rev E board, Program has been executing properly.

Hi Muthraj M,

Did the demo you debug from the KSDK1.2.0 which I suggest or local builded?

Dear Jeremyzhou,

Thanks a lot......

yes whatever you had provided only tested on Both the boards.

Led_demo file.

Rev E- Working fine

Rev C- Jumps directly to "RTOS scheduler idle task" and executing the same infinitely.

[jeremyzhou]

Hi Muthraj M,

I was wondering if you can share the screenshot of the code stuck in the RTOS scheduler idle task when you debug the hello_world demo on Rec C board.

I'm looking forward to your reply.

Hi Muthraj M,

Did this phenomenon still happen when you use the Jlink debug tool instead of the OpenSDA interface?
