KBOOT V1.2

Hi,

 

I am testing KBOOT V1.2 on my FREEDOM K64F platform. I am using KDS 3.0.0 and KSDK 1.2.0 environment.

1) I open the existing bootloader project for K64F without copying option. Then, I generated the *.elf file and works fine.

2) I am using P&E multilink USB to write *.elf to my target board and is running properly.

3) I am using PTB16&17(UART0) as my communication channel.

4) I am running blhost on PC, and using the command "blhost -p COM1,19200". There is no any reply from bootloader on K64F.

5) I am using fixed baud(19200) instead of auto baud detection, and connect to Hyper Terminal, I can't see the data on Hyper terminal.

6) Then, I try to use blhost, and no reply as well...

7) Another question. There are the following calls in bootloader. Could you tell me what the function will be called because I can't find the entrance?

 

s_scuart_byte_receive_callback(kFramingPacketStartByte);

 

 

s_scuart_byte_receive_callback(kFramingPacketType_Ping);

 

 

 

Could anyone tell me where I did wrong, and how to use blhost to talk to bootloader on K64F?

 

Thanks,

 

Christie
