S08SH bootloader

davidr7 — Sun, 22 Sep 2013 08:24:18 GMT

Hey , I tried to run the bootloader for S08SH and it doesn't run. I used the configuration for PortB and I got the FC (ACK) in the PC software.

Afer it always sends ACK again and not continue, I tried to debug it and I saw that the func READ doens't Work ( maybe the problem is in other place). What should I check ?

Thanks David

Hi David,

Hope you are talking about SCI bootloader in AN2295.

Firstly please use the latest AN2295SW, now is AN2295SW_Rev1.

I tried SH32 via SCI(PortB), everthing works fine. That can prove the code is no prolem.

Did you change baudrate? the defaults is 9600.

Hey,

I used the latest version that I found in the forum , if you can please give me a link to the new I will appreciate it.

The correct microprocessor model is : MC9S08SH8CTJ

I use PortB also and I get the first ACK (FC).

The Baudrate is the same ( 9600 ).

After the ACK it says unknown protocol.

What should I do next?

Thanks David

Hi David,

Sorry for so long delay.

In AN2295SW,there is not project for S08SH8 with PTB ports. Only SH32 has such project.

How did you develope your project?

Hey Weiping Xu

I used the next datasheet ( http://www.freescale.com/files/microcontrollers/doc/data_sheet/MC9S08SH8.pdf ) .

You can see in page 28 in PDF file ( not document page) the correct figure ( Figure 2-2. 20-Pin ) , you can see that that port B is Rx/TX.

Also I get the first FC .

I hope I answered your question , How can we continue from here?

Thanks David

Hi David,

That wasn't my mean. I meant there was no corresponding target in the project of AN2295SW.

I added one target named S08SH8-TB1RB0(TxD/RxD) in the bootloader project from AN2295SW. please check the attachment. and select the target as the picture below.

Please have a try, if still get problems, please let me know.
