CW 10.6 flash programmer problem

DK1BN — Wed, 11 Jun 2014 16:34:50 GMT

Hello,

I have a working code (.S19 file -SH32 ) and tried to program it with the flash programmer under CW 10.6 . Before we used CW 6.3 (classical) and we had no problem. We used the hiwave.exe debugger.If I use the "flash to target" under 10.6 all seems to be ok. But there seems to be a problem with the baudrate of the serial port of the MCU(1200bd). I get only garbled characters back. It looks like there is something wrong with the MCU clock. I tried version 10.3,10.4, 10.6 with the same results. There is no problem flashing the .s19 file with "hiwave.exe" of CW 6.3.

Programming adapter used " P&E Multilink Universal"

Here is log file under 10.6

fl::target -lc "LC for Simple Flash"

fl::target -b 0x80 0x400

fl::target -v off -l off

cmdwin::fl::device -d "MC9S08SH32_FLASH" -o "32kx16x1" -a 0x8000 0xffff

cmdwin::fl::image -f "C:\\Users\\walter\\Downloads\\treg232\\treg232.s19" -t "Auto Detect" -re on -r 0x8000 0xffff -oe off

Hello Walter,

I assume you use the internal clock source. I suspect the problem could be related to internal clock trim registers (ICSTRM - TRIM and ICSSC - FTRIM).

NVTRIM, NVFTRIM includes factory or custom trim values in Flash - these are copied into TRIM/FTRIM after reset.

I guess that hiwave.exe debugger does trimming while loading the s-record whereas Flash Programmer does not.

Can you possibly try to compare NVTRIM / NVFTRIM in cw 6.3 vs. CW 10.6?

Hope it helps.

Stan

Hello Stan,

Yes,we are using the internal clock. I think you are correct the hiwave.exe debugger does the trimming while loading the s-record and afterwards the baudrate is correct.

I will check NVTRIM/NVFTRIM. But how is it possible then to program a .s19 file(CW 6.3) under CW 10.x w/o transferring the whole project to 10.x if there is no trimming using the flash programmer (CW 10.x)? How is the trimming accomplished in 10.x?

Regards

Walter

Answer by Freescale Support:

"Thank you for contacting us about this issue.

This problem with the flash programmer not trimming the S08 devices was

already reported to our developers with internal ticket number

ENGR00278719. Unfortunately, they determined not to fix it due to other

product priorities. I am very sorry for this inconvenience. However this

issue is not present when programming the device using CodeWarrior debugger.

And as other alternatives, below you have some suggestions:

1) Using P&E PROGHCS08. This software is not for free, but it does not

have the problem about the trim value. In fact there is a dedicated

command for programming the trim:

http://www.pemicro.com/products/product_viewDetails.cfm?product_id=27

2) Using a Cyclone programmer. This tool can also program the trim at

production.

3) By means of hiwave. As you mentioned, the issue is not present with

this software tool.

I hope my response helps to clarify. If you still have doubts, please

let me know.

Have a nice day!"
