Hi Erich
Thank you very much for your reply.
I followed your instruction to update Bootloader.
- power board with reset button pressed:
- green LED blinks
- copy BOOTUPDATEAPP_Pemicro_v111.SDA to the board. When I try to copy by drag& drop, also by Command prompt window. The loading file it's seem very low ( Freezed), and then the led signify error (2 seconds off followed by fast on/off 8 times). I wait , and the file be copied.
- unpower the board, power the board again (wait a few seconds) (IMPORTANT: this step easily gets missed!)
- unpower the board
- power the board again with RESET pressed
- copy the MSD-DEBUG-FRDM-KL25Z_Pemicro_v114.SDA to the board
- wait a few seconds
- power the board normally. => I don't see any signify for success such as the name of the board or led on.
And then i try to update the MSD-FRDM-KL25Z_Pemicro_v105.SDA.
=> The board works fine on this mode , I check the information as below:
Board Name is: FREEDOM-KL25Z
MicroBoot Kernel Version is: 0.01
Bootloader Version is: 0.00
Installed Application: PEMicro
FRDM-KL25Z Mass Storage App
Application Version is: 1.05
Your instruction is quite correctly, but I don't understand why this happened.
Minh.
