Hello everybody,
im using the FRDM K22F since a week and it was fine so far.
Then I was unable to use Interrupts and got erros like "was unable to acces 0X254 e.g.
After a lot of error searching i decided to re-Install Freescale KDS 3.2.0.
Now im not able to connect to the board.
I instaled:
-KDS 3.2.0
-Serial driver
-SDK2.0 Project Wizard
(Downloaded SDK2.0 for FRDM22)
created "Hello World" Example->build with no error
I can see the mbed drive...
After that i get "Error in final launch sequence"
and the Console says:
"Quit (expect signal SIGINT when the program is resumed)
Exception condition detected on fd 0
error detected on stdin"
I chaned the board, so it is brand new.
It would be verry nice if someone could help a bit.
Thanks a Lot
Jochen
Hello Alice,
i dont want to bore you, but i can not bring any file to the board becouse since the "crash" when I tried to update firmware I´m not able to enter Bootloader Mode.
So if I plug in my board via USB connector (the correct one) It happens nothing.
-NO LED is blinking
-NO green debugger LED
-NO mbed drive.
-NO bootloader drive
What kind of screenshot can I send you? I see nothing... :smileygrin:
Sorry for the Problems...

Hello Jochen,
That is too cruel to believe . Does you only copy and past the MBED file of "0221_k20dx128_k22f_0x8000.bin", then the board can not enter into bootloader mode ?
Could you please use your mobile phone recording a video when operate the board running to bootloader mode , then send to me ?
Sorry for the inconvenience to you !

So I tried to update Firmware with another board and have the same result. Its down now.
A Third Bord only shows the bootloader drive out of the Box, and now "mbed" drive.
Now I have one Board left that works. Or lets say, 3 of 4 Boards are not working. I am running out of ideas...
Have a nice Day
Jochen
Hello Jochen,
Sorry i have not the Win10 system , i test it on Win7.
Which file do you drag&drop ? 0221_k20dx128_k22f_0x8000.bin? I attached it .
And if still can not work , could you please use j-link interface ? I also attached the
firmware for j-link "JLink_OpenSDA_V2_1.bin ", the update method is the same .
Hope it helps

Hello Alice,
yes it is the same file, that failes here at my board. How can I bring the j-Link File to the board in the same way, if I don't see the mbed drive or bootloader drive? Should I really try it with my last working board? :smileygrin:
Hello Jochen,
Do not need use the last board, you can use the board you have test .
How do you bring the file of "0221_k20dx128_k22f_0x8000.bin" ? The same as bring J-link file .
The step as below:
If still can not work , please take screenshot about the steps you did , it is better also the hardware you operate ,
give me more information , then i can know your problem clearly .

Hello and thank you for fast answering!
i tried to update the firmware at my first board, but after "drag&drop" the file to the bootloader drive, Windows (10) told me that there is not enough storage. Now the board is dead. That means no green LED next to the RESET button and not USB Drive at my PC. I dont want to kill my secon board as well...
I already tried the piont with the Disconnection bug.
