Thanks for your prompt reply.
I confirm I have STM8S103K3 prototypes.
Waiting for good news then.

Hi,

i have the same problem. If i want to debug or flash
the STM8S103K3T6C$U1
i get the error message "No response to the DTC".
Is there already a patch for this problem?

Hi,

I have made a patch but there have been some issues and it is still under validation by MCart.
If you want to give it a try, you can take the latest version here:
ftp://... <<<< Edit: this file was wrong. see new version below >>>

Keep in mind that these are test files, not guaranteed to work and potentially introducing more problems than they solve. (that means save the old files before using these!) Anyways, any feedback is welcomed.

Best Regards,

Vincent

Well, it looks like there is (again) a problem with our new ftp server.
Here is the file on the old server:

Hi Vincent,

the first debugging steps with the patch are working fine.

Thanks!

Hi,

Thanks for your feedback.

MCart found a problem with Option Bytes in the previous patch.
Here is the new version:
ftp://217.71.112.106/temp/ST/patch_090303_STM8S103K3.zip

Hi Vincent,

the debugger RLINK programmes the default values of
the option bytes. RFlasher7 programmes the values i
defined in the asm-file.
How can i tell the debugger to program my values?

I've installed the newest patch above.

Hi,

The debugger programs the Option Bytes fine on my PC. There are a few things to take care of though:

The debugging cannot work if read or write protections are set.

It is your responsibility to make sure that the values in the complement bytes are consistent with the 'normal' ones.

What values are you trying to program in the Option Bytes?

How do you observe that they are not programmed? (in the memory view? in the behavior of the chip?)

Vincent

Hi,

i want to map the TIM1_CH1N of the STM8S103K2T6 to PC3.

The option bytes are:

-------------------------------------------------------------------
;This file contains the values to program in the option bytes.
;You can change the values below according to the device datasheet.
;Be careful to respect the complement bytes,
; or the default values of the option bytes will be used.

;See the device datasheet for more information on the meaning of each bit.

end
------------------------------------------------------------------

At debugging i can measure the TIM1_CH1N signal at PB0.
To verify the option bytes i read out the chip with RFlasher.
In the code window at 0x4800 i see that the debugger programmed
the default values.
Then i used RFlasher to program the hex file to the chip.
After reading the flash memory of the chip i see at 0x4800 my
option bytes.

How can i attach files in a post?

Hi,

Are you using the STM8S103K2 or the STM8S103K3?

The patch I sent is only for the STM83S103K3. I don't expect it to work on the K2. Please confirm and if needed I will send you a patch that also handles the K2.

Best Regards,

Vincent

Hi,

i am using the STM8S103K3T6C$U1

Hi,

I can reproduce this problem, but I will need the intervention of some colleagues to solve it, so I cannot send you a patch before next week.

Thank you for reporting the issue.

Best Regards,

Vincent
