Hi,

 

Here is a notice when using blhost to program KL03.

 

Issue Background:

To program KL03 by blhost.exe, user will get the flash is in security state as below message:

 

Input 1: blhost.exe --p com47,38400 -- get-property 17

 

Respond Message:

ping responded in attempt(s)

Inject command 'get-property'

Response status=0 <0x0>Success

Response word1=1 <0x1>

Flash Security State = SECURE

 

 

Input 2: blhost.exe --p com47,38400 -- flash-erase-all

 

Respond Message:

Ping tesponded in 1 attempt(s)

Inject command 'flash-erase-all'

Response status=10001 <0x2711>Command disallowed when security is enabled

 

 

The symptom is similar to programming fail by BDM in some cases. The solution is down BDM speed.

So set the baud rate speed down to 9600 with each command and the problem is gone.
